STANDARD SPEEDFIT FITTINGS
MAKING A GOOD CONNECTION
Push pipe up to stop
PREPARE THE PIPE
Fittings and pipe should be kept clean bagged and undamaged
before use.
HOW SPEEDFIT WORKS
Pipe mark indicates
full insertion.
Secondary Seal
Ensure the pipe is free of score
marks. Cut the pipe square.
When using Speedfit Barrier Pipe
cut along an insertion mark. We
Speedfit Fittings have a unique grip then seal construction made up of a collet with stainless
steel teeth to grip the pipe and an ‘O’ ring to provide a permanent leak proof seal.
Standard Speedfit connections are made in the same way
as Twist and Lock.
Use of the Superseal Pipe Insert ensures a double ‘O’ ring seal.
recommend the use of JG Pipe
Cutters.
Pipe Cutter
JG TS
Push Pipe up to Pipe Stop. If the Speedfit Pipe has been
cut correctly the insertion mark on the pipe will be level
with the collet head.
An ‘O’ ring at the head of the insert and the shape of the stem, provide a secondary seal against
the bore of the fitting. A combination of this and the main ‘O’ ring ensure a good connection.
Speedfit
Barrier Pipe
The stem of the insert gives greater rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.
To prevent damage to the ‘O’ ring
remove all burrs and sharp edges.
When connecting Speedfit Pipe
use a Superseal Pipe Insert. A
twisting motion will aid insertion.
The insert should only be used
with Speedfit Pipe.
Pull to check connection
is secure and test the
system. Our recommended
test procedure is shown
in our Technical Checklist
on page 29.
The head of the insert has been designed for ease of insertion.
The additional benefit of Twist and Lock Fittings is that a twist of a screwcap locks the pipe in
position and gives increased compression on the ‘O’ ring for even greater security.
TO DISCONNECT
NEW TWIST AND LOCK FITTINGS
Ensure that the system
is depressurised.
Gap between Cap
and Flange
Grips before it seals
The screwcap on Twist
and Lock Fittings will
need to be turned back
to the unlocked position.
Pipe mark indicates
full insertion
Push the collet square against the face of the fitting by
using fingers or with the help of our collet release tool.
The fitting should be in the ‘unlocked’ position, this is
shown with a small gap between the screwcap and the
body flange.
With the collet held in position the pipe can be removed.
Stainless steel teeth
grip the pipe
The fitting can be used again without the need for
replacement parts.
Push the pipe fully into the fitting, up to the pipe stop. If
the Speedfit Pipe has been cut correctly the insertion
mark on the pipe will be level with the collet head. The ‘O’
ring on the Superseal Pipe Insert provides a secondary
seal against the bore of the fitting. A good connection
has been made.
WHAT NOT TO DO
Don’t use hacksaws to cut the
pipe or leave burrs on the end of
the pipe.
If you are not using collet
clips, ensure that the
screwcaps are in the
locked position.
Don’t use
damaged or
scored pipe.
Pull to check it is secure. It is good practice to test the system
prior to leaving the site or before use. Our recommended
test procedure is shown in our Technical Checklist.

Twist the screwcap until it

This increases the ‘O’ ring
seal around the pipe and
locks the pipe into position.
Don’t forget to push the
pipe fully into the fitting,
past both the collet (gripper)

and the ‘O’ ring.
Fitting may be gripped but not
sealed if pipe is not fully inserted.
Do not insert fingers into the fitting as the stainless steel
teeth may cause injury.
Remember to pressure test the completed installation

TAP CONNECTORS
STOP END
SPEEDFIT MANIFOLD
The unique feature of the
Speedfit Concept, the ability
to disconnect the fitting
should you want to, means
the Speedfit Stop End not
only provides a permanent
leakproof seal, but can be
readily removed to allow
work to restart or to allow
an extension to a system.
Thus, the fitting is especially
useful to allow water to be
turned back on, overnight for
instance, or if a job has to be
interrupted for another reason.
Speedfit manufacturer a wide range of connectors
including conventional straight and bent tap connectors.
Speedfit have introduced an innovative 22mm x 10mm 4
way manifold. Departing from the usual manifold design,
this new product has 4 in-line 10mm outlets, offering a
neater envelope size and therefore a much smaller
installation space.
PIPE STOP DISTANCES
Stops are located at the following distances from the end
of the fitting:
Other benefits include better flow characteristics and a
more even distribution of hot water.

stop distance
The 22mm and 10mm Speedfit push-fit connections make
for a fast and easy installation, even in confined spaces.
The range also offers a special and
unique Tap Connector that only
requires a simple hand tightening to
connect up a terminal tap, mixer or
float valve. An integral seal within the
fitting avoids the need for further
sealant. The connectors are useful
when replacing existing brassware or
in other confined spaces.
Stop end
Whilst designed as a heating product, the manifold can
also be used in a mains pressure hot or cold domestic
plumbing system, to feed bathroom or kitchen taps and
mixers. This allows for a more efficient installation as
every terminal fitting has its own dedicated supply.
Stop ends are also useful when pressure testing a system
before appliances are connected.
COLLET COVERS
STEM ELBOW
Coupling up to a supply is easy. The
pipe is simply pushed home into
the Speedfit connection and is
instantly secured, without the need
for specialist tools.
Use a collet cover or collet clip to provide added security
against pipe disconnection, e.g. the fitting coming into
contact with rigid surfaces and behind dry-lining walls.
Designed to simplify pipe connection
in restricted spaces. The Speedfit
Stem Elbow provides an instant swivel
fitting so pipe can be orientated in
any direction.
Collet covers for use with standard Speedfit fittings, are
available in white or in red or blue to allow colour coding of pipes.
APPLIANCE TAP
A special 10mm version gives a neat
connection from concealed plumbing to
a radiator.
Collet cover
The Speedfit range includes an Appliance Tap for
the permanent connection of washing machines and
dishwashers, thus enabling complete water isolation to
the appliance.
FLEXI HOSES
COLLET CLIPS
Collet clip
SERVICE VALVE
Manufactured to a quality you would expect from Speedfit,
our range of Flexi Hoses has 40 different patterns.
The Speedfit range of brass
chromium plated service
valves can be used on both
hot and cold water services
and central heating. Push fit
connections mean much
reduced installation time,
especially in confined spaces.
A simple push fit connection of the supply pipe and a
plastic thread on the outlet to marry well with the plastic
thread on the hose means the Speedfit Appliance Tap is very
easy to install. The large round handle is easy to grip and turn.
Available in lengths from 150mm to 1,000mm, ends are
either push fit to union nut or push fit to push fit, including
hoses with an integral service valve operated by a 1/4 turn
screwdriver slot.
Collet clips are available in grey and white for use with
standard fittings to prevent accidental pipe
disconnection.
SUPERSEAL PIPE INSERT
Apart from being aesthetically pleasing the new white
hoses offer more flexibility and a larger through bore
for better flow characteristics.
The Superseal Pipe Insert has been developed to be used
with Speedfit Barrier Pipe and Speedfit Fittings to provide
an extra line of defence when installing a Speedfit Push
Fit System.
Red or blue collet clips provide colour coding of pipe on
twist and lock fittings.
The valves, in 10 to 22mm,
have a 1/4 turn open/close
mechanism operated by a
screwdriver slot or a lever.
They are not designed to prevent accidental release and
should be fitted when the fitting is in the locked position.
The insert has it’s own ‘O’ ring which, with a stem sliding
within the inside of the pipe, gives a secondary seal
against the inside of the fitting.
Tap connector patterns have
a union nut to connect
direct to a tap or floatvalve.
Lever operated valves are
supplied with both a blue
and a red indice.
More specialist patterns
have been designed to help
the installation of monobloc
mixers to a 15mm supply.
Sold in pairs, each hose in
the pair has a different
spanner location to ease
connection of the threaded
end into the monobloc’s
inlets.
The ability of Speedfit products
to twist whilst in situ
allows the screwdriver slot
operating valve to be turned
out of sight, helping to avoid
unauthorised tampering.
RELEASE AID
The Speedfit Connection, when made with the insert, has
a number of design features.
The action of pressure in a system could increase the grip
of the collet. The release aid allows a firmer grip on the
collet whilst removing the pipe.
Sliding the stem of the insert into the pipe gives greater
compression of the main ‘O’ ring on the pipe and greater
rigidity of the length of pipe within the fitting, reducing the
chance of leaks if a side load is applied.
Release aid
Speedfit x Speedfit
A connection is easier to make because the head of the
insert has been designed for ease of insertion.
Mechanism twists out of sight
The hoses are suitable for cold water up to 10 Bar and
hot water (65˚C max) up to 6 Bar and approved by WRAS.

PIPE AND PIPE ACCESSORIES
These systems are very different from more conventional
domestic hot water and central heating systems.
When using compression fittings with Speedfit Pipe, a
Standard Pipe Insert (prefix TSM) must be used to
withstand the compressive pressure of the olive. The olive
must be located within the the length of the pipe insert
and the pipe fully inserted into the fitting. The connection
should not need more than 2 full turns after the olive has
gripped the pipe. JG Speedfit recommend the use of soft
copper olives.
Speedfit Products cannot be used on ring main systems.
The exception would be those systems designed for
domestic situations which have an intermittent
temperature of less than a maximum of 65ºC. This is in
accordance with BS7291 Parts 1 and 3 Class S.

Water meters (and other devices) can contain check
valves that prevent the expansion of heated water back
down the main supply from a combi boiler. If plastic pipe
is to be used, a suitable expansion vessel must be fitted.
This is especially important to consider if a water meter is
fitted retrospectively. Speedfit do not recommend the use
of plastic pipe on the main supply between a water meter
and a combi boiler if an expansion vessel is not fitted.
Speedfit fittings can be connected onto chromium plated
copper pipe if the chromium plating is completely
removed to the full depth of the fitting. To ensure
maximum grip, the fitting of a collet clip is recommended.

INSTALLING PIPEWORK
IEE Guidance Note 7 provides useful guidance on the
design of electrical installations where there is increased
risk of electric shock. It recognises that the requirement
for supplementry bonding may be relaxed where metal
taps and plastic pipes supply other bathroom fittings.
Speedfit pipe should be connected to circulating pumps,
motorised valves in accordance with the section in this
book headed, “Connecting Plastic Pipe To Compression
Fittings”. If Speedfit pipe is not mounted on a supporting
structure, the pipe must be clipped close to the components’
connections to ensure adequate support and to assist in
the reduction of vibration.
SPEEDFIT BARRIER PIPE
Speedfit Barrier Pipe is manufactured to BS 7291 Parts 1,
2 and 3 Class S and is Kitemarked.
CONNECTION TO CYLINDER & WATER
HEATERS CONTINUED
It is made up of 5 layers, the
centre of which is a blue
coloured oxygen barrier
which prevents the ingress
of air into the system, thereby
reducing the effect of corrosion
on metal components.
Similarly a metal bath or radiator not connected to an
extraneous-conductive-part is not required to be connected
to the local supplementry conductors.
Unvented pressurised cylinders can be installed using
Speedfit Pipe and Fittings. However, insertion depths on
compression joints that form part of the cylinder must be
checked prior to installation and the use of standard pipe
inserts (Prefix TSM) is recommended.
For heavier equipment, ensure that appropriate metal
brackets provide full and independent support of the
components and that it does not rely solely on the pipework
for support.
In accordance with current U.K. Building Regulations
(Part G), discharge pipes from temperature and/or pressure
relief valves must be run in metal pipework.
WATER HEATERS
Earth Lead
Because of it’s low thermal conductivity, when carrying
hot water, Speedfit Pipe is cooler and therefore safer to
touch. Relatively low heat loss through radiation means that
a system retains it’s heat longer and delivers hot water
more quickly and with less wastage than a metal system.
Speedfit recommend that mains supply pipework to unvented
water heaters (up to 15ltr capacity), be run in metal pipes.

UNVENTED PRESSURISED CYLINDERS
Speedfit Pipe and Fitting
Unvented Pressurised Cylinders can be installed using
Speedfit pipe and fittings. However if the safety
parameters of the cylinder exceed those of the pipe and
fittings it is possible to fit a pressure reduction valve on
the out going hot supply pipe. This will not interfere with
any other cylinder safety devices demanded by
regulations as they are all fitted in the incoming side of the
cylinder. Run a short length of copper pipe from the
cylinder connection (about 150mm - 300mm) then fit a
Honeywell DO5F pressure reduction valve. This will
protect the pipe and fittings from excessive pressure in
the event of boiler / cylinder malfunction. The factory
fitted temperature / pressure relief valve on the cylinder
will discharge below 100˚C therefore protecting the pipe
from excessive temperature.

For general guidance on pipework sizing, please refer to
BS6700 and BS5449 or the Institute of Plumbing
Engineering Services Design Guide. Speedfit fittings are
suitable for connection to pipe sizes within 0.1mm of
nominal size.
Several types of joists are available and Speedfit recommends
that specific manufacturers details are consulted.
However, the following can be used for general guidance.
To prevent surface damage to the plaster caused by
expansion and contraction of Speedfit pipes, it is
important to ensure that all Speedfit pipework is
channelled into the wall and protected with appropriate
sleeving. Alternatively, the pipework can be surface
mounted and boxed in if required for aesthetic appearance.

Unlike I beam joists, pipe can be cabled anywhere within
the open Web as no drilling is required. However, the top
and bottom flanges must not be notched. Avoid
damaging the outside diameter of the pipe as you cable
Speedfit Conduit Pipe is supplied
in either 15mm or 22mm in coil
lengths of 25m or 50m. The flexible
convoluted pipe has an outside
diameter of 24mm and 30mm.
PIPEWORK INSULATION
The insulation requirements for Speedfit pipe are the same as
those for copper and should comply with BS6700 and BS5422.
It is also possible to bend Speedfit Pipe using a standard
pipe bender. The pipe should not be heated with a
blowlamp or hot air gun.
through the metal cross web members
.
CONCEALED PIPEWORK
Minimum bend radii for Speedfit pipe are as follows:
The flexibility of Speedfit pipe gives it the ability to be
threaded through concealed or inaccessible spaces
without disruption to surrounding structures, making
major savings in installation time.

EXPOSED PIPEWORK
10mm 15mm 22mm 28mm
On long exposed runs of pipework, the expansion of
Speedfit pipe when warm (1% on length between 20 to
82°C) can cause it to sag between clip fixings. When this
is undesirable, pipework can be boxed in or replaced with
rigid copper pipe. Speedfit pipe and fittings are stabilised
to withstand limited exposure to ultra-violet radiation in
sunlight but are not designed for permanent direct
exposure. Under such conditions painting or lagging is
required. Pipe and fittings should also be lagged to
prevent frost damage.

Pipework can be “cabled” through drilled holes in joists
and rafters. Therefore, pipework can be installed after
floorboards have been laid, working below the floor
before the ceiling is installed.
with Clips 100mm 175mm 225mm 300mm
For bends of radii smaller than those shown, standard
elbow fittings are recommended.
TIMBER FRAMED CONSTRUCTION
This makes site work far safer as the installer does not
have to balance on open joists with the risk of dropping
tools or equipment on other people below.
Speedfit is well suited for timber frame construction.
Ensure that the structural integrity is not compromised
when installing the pipework.
PIPE SUPPORT AND CLIPPING
There are two types of pipe clip in the Speedfit range.
Firstly, a nail clip is used for fixing to timber
when running concealed pipe work i.e.
underfloor or in a roof space . This clip takes
less time to fit and is compact which allows
pipework to be fixed close together when
space is at a premium.
Speedfit pipe
Joist
If the pipe passes through an external wall, care must be
taken not to damage the vapour barrier and should be
installed on the inside of the thermal insulation layer.
CHEMICAL EFFECTS
Clips
Only water or oil based paints should be used. Do not
allow Speedfit fittings to come into contact with cellulose
based paints, paint thinners or strippers, solder flux or
acid based descalents or aggressive cleaning products. If
there is a risk of any chemical treatments coming into
contact with Speedfit, please contact the Technical Advisory
Service first to check compatibility.
If this is not possible, the use of conduit should be specified
at the design stage.
This will also eliminate the risk of damage by floorboard
nails. There is no need for dry runs since pipe can be cut
and connections made in-situ.
The second type uses a screw and therefore
takes a little longer to fix. When pipes are
required to cross over, it is possible to add
a spacer to the clip. This will give room
between the pipe and the wall to allow the
pipes to cross over. If pipework needs to be
insulated, using the spacer will give room for
the lagging to be applied.
STEEL FRAMED CONSTRUCTION
Rigid pipe, such as copper, can only be fed under floor in
short lengths. However, Speedfit pipe, being flexible, can
run from one fitting to another without having to install a
connector in between.
Speedfit is well suited for steel frame construction and
care should be taken when installing the pipework.
FLUXES AND SPEEDFIT
All runs should be installed through preformed holes in the
structure and protected by a rubber or plastic grommet.
JG Speedfit does not recommend that fluxes of any type
come into contact with our pipe and fittings. However, if
fluxes are to be used in an environment where Speedfit
is installed then we recommend installers use non-acidic
and zinc chloride free fluxes such as Fernox Flux.
Speedfit needs no jointing materials, eliminating the risk of
fire from the use of a blowlamp, solder and flux
.
Where clipping of pipework is restricted, cable ties may
be used to secure the pipe.
Pipe clips should not be fitted any closer than 60mm from
the end of the fitting to allow for expansion. Pipes should
always be adequately supported to prevent undue stress
or side load on the fittings.
TRADITIONAL JOISTS
Instructions on the drilling of joists is given in the Building
Regulations Approved Document A, and summarised as
follows:
As with all installations, make sure that any pipework passing
through walls and floors does not affect the fire resistant
properties of the structure.
ACOUSTIC
RECOMMENDED CLIP SPACING
For surface mounted pipes
1. Holes should be no greater than 0.25 of the depth of the joist.
2. Holes should be drilled at the neutral axis.
Properly installed, Speedfit pipes are virtually silent in
operation and do not resonate; they absorb the acoustic
vibrations and pressure waves created by cavitations,
water hammer, float operated valve oscillation and other
hydraulic effects. The inherent flexibility of Speedfit pipe
effectively eliminates these troublesome problems, including
those that occur when, due to thermal expansion, metal
pipes rub against structural members and where long,
straight runs of rigid pipe amplify water borne noise.
DRY LINED WALLS

most commonly used to feed radiators.

During the commissioning of a heating system, all air
must be removed from the system before the boiler is
allowed to fire. This will ensure pockets of air do not
cause localized overheating within the system as this
could have a detrimental affect on the pipework and
boiler.
RADIATOR SYSTEM AND HEAT GRADIENT
By contrast, radiators transfer heat from a relatively small
area at a much higher temperature than the space being heated.
The radiator system heats mainly by convection. This
results in the floor being the coolest place in the room,
with the mass of warm air at ceiling level.
UNDERFLOOR HEATING
PROTECTION AGAINST RODENTS
The Speedfit Underfloor Heating System has been designed
to be as quick and easy as possible to install with component
parts manufactured to UK and European standards.
When used in locations vulnerable to rodent attack, all
plastic pipes and fittings should be adequately protected
within sealed ducts.
For further advice on chemical flushing agents and
inhibitor treatments, the following manufacturers should
be contacted: Fernox Manufacturing Ltd., 01799 550811
or Sentinel Betz Dearborn Ltd., 0151 420 9595.
Underfloor heating provides the most comfortable even warmth
of any heating system. It is economical to run and virtually
maintenance free. The principle has been with us since
Roman times but is still the system of choice in some
European countries, accounting for 70% of installations.
Speedfit products along with other materials such as
electrical cables may be damaged if rodents are present.
If vermin infestation is suspected then a rodent exterminator

Advisory Service.
should take appropriate action
.
BIOLOGICAL
The Speedfit System has water being pumped from a
boiler to a pump pack, where it is mixed to approximately
50ºC then distributed via a manifold to heating circuits
made using Speedfit Barrier Pipe. The pipe is laid in
concrete or suspended just below the surface of the floor.
No taste, colour, odour or toxicity is imparted to water by
Speedfit components, nor do they promote
microbiological growth.
Floor
18°C
In accordance with BS7291: Part 1 Clause 6.7, the opacity
of both pipes and fittings allows insufficient light to pass
for the growth of algae
In concrete floors, the pipe is laid on insulation and then
covered with a screed on which can be laid almost any type
of floor covering.
FEATURES & BENEFITS
We take pride in the quality of our products and all complaints
are investigated thoroughly. If you have a problem with a
Speedfit Product please return both fitting and pipe to us
for investigation. We will need at least 50mm of pipe to
ensure an accurate analysis. If there is a suspicion that the
pipe is faulty, please provide marking details from the pipe.
The Speedfit Underfloor Heating System offers many benefits
to the consumer. These include:
Tests within the Water Regulations Advisory Scheme,
have approved Speedfit pipe and fittings to BS 6920 for
water quality.
For timber floors, spreader plates are laid between the joists
and the floor decking or on the underside of the floor.
Speedfit Pipe is pushed into the grooves on the plates.
Installation
It is simple to install, requiring the minimum of installation
effort and little maintenance.
SYSTEM TESTING
The floor area is typically warmed to between 25ºC and
28ºC, providing an even distribution of heat at only slightly
higher than room temperature. The system is controlled
by one or more thermostats which signal the Pump Pack
when heat is required.
On completion of the plumbing and heating system it is
essential that system checking and a hydraulic wet test
takes place. Connections to boilers, radiators and
sanitary ware should first be capped or plugged.
Comfort
The system uses radiant heat, the most comfortable form
of heating, to give a good even distribution of warmth
over the whole room.
COMMON PROBLEMS AND IDENTIFICATION
Problem: Burst or melted pipe.
Testing should be carried out at
2 bar for 10 minutes followed by 10
bar for 10 minutes.
Pipe will be distorted showing either a ‘Parrot beak’ look
or a long opening with the edges of the pipe melted in a
wave shape.
Space
UNDERFLOOR HEATING SYSTEM
The system in unobtrusive and space saving which means
every square metre of floor and wall space can be fully
utilised giving freedom of interior design.
An Underfloor Heating System heats mainly by radiation.
Radiant energy is emitted by the floor giving an even
distribution of heat. No cold spots, hot ceilings or cold feet.
This testing combined with other
relevant checks, should reveal most
system problems. Any components
within the system not designed
to take these pressures should
be disconnected.
Identification: A ‘Parrot beak’ will have been formed by
the pipe bursting due to the water freezing. If the Pipe has
a melted appearance it will have been subject to a
temperature in excess of 128 degrees Celsius. This will
have been caused by direct contact with a heat source
such as a blowtorch or flue pipe or by water or steam
within the system rising above safety levels.
Noise
Compared to radiator systems the system is virtually silent running.
The overall effectiveness of an UFH heating system can
be seen below.
Health
Dust is minimised reducing the problem of house dust
mites. Reduced numbers of hot surfaces and sharp edges
minimise risk of burns or injury.
The heat is concentrated where it is most needed for
comfort and efficiency.
Before carrying out a pressure test
ensure all Speedfit pipe and fittings
are installed correctly. Speedfit
Barrier Pipe is printed with insertion
marks to help ensure full insertion
has been achieved.
Problem: A fitting or part of a fitting dissolved - the fitting
may have blown off the pipe and may have missing
component parts.
Economic
Underfloor Heating Systems are designed to operate at
lower temperatures than radiator systems, resulting in
reduced energy consumption and lower heatloss from the
building structure.
Ceiling
18°C
Identification: The fitting will have failed because of a
chemical attack. The most common attack is from acid
based solder flux running down into the fitting during
soldering of a nearby copper fitting or flux coming into
contact with the fitting in some other way.
Remember pressure testing is NOT a substitute for
making sure fittings are clean and free of any grit, dirt or
swarf and the pipe is correctly inserted (see Making a
Good Connection, on page 06.
Control
The system is easy to control and the small temperature
difference between the floor and air means the system is
virtually self - regulating.
Problem: Weep from fitting.
SYSTEM COMMISSIONING AND FLUSHING
Environment
Identification : The pipe has not been fully inserted up to
the pipe stop or one or both of the ‘O’ rings have been
damaged by burrs or sharp edges on the end of pipe. See
‘What Not to Do’ on page 06.
Floor
24°C
With existing systems, flushing prior to the use of Speedfit is
essential to remove any harmful contamination or chemical
residues from elsewhere in the system.
Underfloor heating is suitable for use with the most energy
efficient and environmentally friendly heating systems
including condensing boilers, solar power and heat pumps.
For the installation of central heating systems flushing
procedures must be in line with BS7593 code of practice
for treatment of water in domestic hot water heating systems.
Problem: The fitting has blown off the pipe. Fitting is
missing the collet, the pipe insert is still inside the fitting
after the pipe has come out.
FLOOR FINISHES AND COVERING
The Speedfit Underfloor Heating System is suitable for
most floor finishes, including ceramic tiles, carpets, vinyl
and laminate.
Flux residues used in the soldering of capillary fittings are
very corrosive. Dirt and grit, which can enter the system
when Speedfit pipe is being pushed through underfloor or
across a roof space, must be removed.
Identification: If this happens on first fix, the most likely
reason is that the pipe has not been fully inserted into the
fitting, up to the pipe stop, and the system has not been
pressure tested.
The thermal resistance of floor covering will have a marked
effect on the performance of the heating system.
Advice on the use of floor coverings and their effect on
the performance of a system is laid out in the Speedfit
Underfloor Heating Manual.
If the collet (gripping device) is missing everything will
blow out. If the collet is there and the pipe support is still
inside the connector but the pipe has still blown out, this
means that full insertion had not been accomplished.

Performance. The fittings are manufactured from tough plastic
material well able to meet the stringent requirements of the water
industry. They have been approved by the WRAS and, as such,
have passed the ʻpull out testʼ where a force shown below is applied
to a connection between MDPE pipes and a fitting for 5 minutes
without the connection failing.
Connection to copper pipe. 450mm is the minimum distance to make
a solder connection on copper pipe inserted into a Speedfit Fitting. Ensure
that any residual flux solder does not come into contact with the fitting.
Concrete and masonry. Speedfit pipe and fittings can be laid in concrete
and masonry providing they are installed in conduit pipe with access boxes
for the fittings. This is to enable the pipe to expand and provide accessibility
for both pipe and fittings. As stated in Water Regulation Scheme 2.7 and BS
8000 : Part 15, fittings and pipe should be removable for possible replacement.
Insulation is also recommended to protect against heat loss and the effects
of frost.

Collet Covers. Collet covers provide added security against pipe
disconnection, e.g. the fittings coming into contact with rigid surfaces
and behind dry-lining walls. They are offered in white as standard and
in red or blue to provide colour coding of pipe.
Collet Clips. Grey collet clips are used with standard fittings to prevent
accidental pipe disconnection. Red or blue clips provide colour coding
of pipe. Red and blue clips should not be used to prevent accidental
release of pipe.
System testing. To ensure the pipework and fittings have been installed
correctly, whether it be on a new or extended system, it is essential that the
system is checked and hydraulically wet tested. Testing should be at 2 bar
for 10 minutes and 10 bar for 10 minutes. This testing, combined with other
relevant checks, should reveal installation problems and is regarded as good
plumbing practice. However, system testing should not be regarded as a
substitute for correct installation (see also “Making a Good Connection”).
System flushing. As is usual practice for any plumbing installation, flushing
of the system prior to the use of Speedfit is recommended to remove any
contaminants/chemical residue from elsewhere in the system.
British Gas Service has accepted the John Guest Speedfit fittings as being
suitable for open vented and sealed central heating systems and as eligible
for acceptance onto its service contracts.
Vermin. Speedfit products will need special protection in vermin infested areas.
Maximum Torque figures (BSP & BSPT). Plastic threads are not generally as
strong as brass threads. Customers and end users should be aware of this
when choosing products for their applications. Overtightening of plastic threads
will cause undue stress and eventual cracking and leakage. The maximum
torque figures for BSP and BSPT threads used on Speedfit plumbing products
in mating threads conforming to the relevant BS or International thread
standards are shown below.
Collet Clips. White and Grey collet clips are used with standard fittings to
prevent accidental pipe disconnection. Red or blue clips provide colour
