DESIGN SECTION
Introduction
Equator is the culmination of extensive world-wide
research into fitting and system design, material
composition and performance capabilities. The result is
a uniquely designed fitting, patent pending, offering the
following benefits:
• Fitting
is fully de-mountable and reusable
• Fitting
is tamper proof. Only through use of the de-
mounting tool can the system be disassembled
• Excellent
• PE-X
chemical resistance
gives good temperature resistance, more so than
many other
non-thermosetting plastics used in the building industry
• Long
term durability
Manufactured from cross-linked polyethylene (PE-X),
which is a high engineering grade polymer, Equator
offers excellent performance capabilities, and its
benefits, both practical and financial, present a real
alternative to copper systems.
For over 30 years PE-X pipe has been dominant in
underfloor heating applications throughout Europe.
Excellent chemical resistance, long term durability and
performance capabilities make PE-X an ideal material
for hot & cold and central heating installations.
Equator has been designed to meet, and in many cases
exceed the requirements of BS 7291: Parts 1 & 3: Class S.

Notes
1 When joining two or more manifolds together, it is
necessary to achieve correct tightness of the thread,
and at the same time to ensure alignment of the
manifold bodies. To ease this problem, installers
are recommended to use a WRAS approved
anaerobic paste sealant. These modern sealants
require much less torque yet will still provide an
effective seal, after the chemical has set.
2 If it is necessary to remove a valve stem from the
manifold body, it is recommended that a 15mm box
spanner or ring spanner is used, to avoid damage
to the brass hex-shaped stem.
3 These dimensions are in mm, and are for general
information only. Marley reserves the right to make

Heating applications
For central heating systems
the plain manifolds, without
valves, are normally used. A
radial pipe configuration from
a central location is typically
designed using these
manifolds, see opposite for a
typical flat layout using this
type of configuration.
The designer should consider
whether air vents and drain
cocks located at the manifolds
would be required. When the
manifolds are located at low
level on the same floor as the
radiators, it is unusual to
provide drain taps on each
radiator circuit, providing the
main circuits, boiler and water
in each radiator can be emptied
from suitably placed drain
cock(s) located elsewhere.

NB.
Further Equator technical assistance
If a pipe end pulls out of a push-fit socket, i.e. because it was only partially inserted, the fitting must not be re-used
as the grip ring may have become damaged.
In the event of a complaint on a suspected faulty fitting, both the fitting and the jointed pipe end must be retained.
The pipe length should not be less than 100mm long.
If after investigation of the fault no cause can be established please contact the Marley Plumbing & Drainage
technical hotline on 01622 852695.

Recommendation
Protecting PE-X from UV damage
PE-X pipe and fittings must be protected from UV degradation as prolonged exposure to
sunlight could affect the longevity of the material.
Products stored internally or within sealed product packs or installed within the building will
not be at risk.
Short-term exposure to UV on building sites will not affect the PE-X products.
•
Do not store bare PE-X products outside.
•
Do not install PE-X product outside without insulation.
•
Storing and handling pipes
In hot climates where insulation is unnecessary, do not install PE-X product outside without
painting or covering to prevent UV damage.
Cut lengths of pipe should be stored flat on a pipe rack, with continuous support.
Coils may be stored either on edge or stacked flat one on top of the other, and provided with
suitable racking to ensure stability. When coils are vertically stacked, the stack height must not
exceed 2m.

Storing and handling fittings
Fittings should be kept within the polythene bags wherever possible and stored in suitable racking.
Note
Do not push fingers into the push-fit
sockets, the sharp stainless steel grip
ring could be dangerous
Bare fittings should be stored in a clean dirt free environment.
When handling or storing bare fittings do not allow any objects to slide into the socket to
avoid damage to the joint internals.

Appendix K
Use of Equator with other systems
GUIDANCE ON MIXING OF EQUATOR WITH OTHER PLASTIC SYSTEMS
•
The random mixing of push-fit systems throughout an entire new project should be considered as bad practice.
•
Connections to other push-fit systems where necessary (such as jointing to existing services, or when connecting to equipment
supplied with other connectors) should be regarded as reasonable, in which case the guidance below should be observed.
•
The following guidance is issued in good faith, however the installer should be aware that both the Marley 30 year guarantee and
any other push-fit manufacturer’s warranty would only be valid where ALL jointing components are from one jointing system.
Recommended Pipe Support Sleeves for 15mm Connections
Hep2O
Polyplumb
OsmaGold
Speedfit
Equator
pipe
Use an Equator sleeve (others have a smaller O.D. and may not give adequate
support to the pipe).
Use an Equator or
Speedfit Sleeve.
Equator
socket
Use the sleeve relevant to the pipe, but as the sleeve length is shorter than the
Equator sleeve, the pipe adjacent to the joint must NOT be curved in any way. (An
Equator sleeve would be a very tight fit, and would expand the pipe O.D. which
could then cause O-ring damage).
Use an Equator sleeve
(Speedfit sleeves are not
chamfered and could
damage the Equator O-ring).
Recommended Pipe Support Sleeves for 10, 22 & 28mm Connections
Hep2O
Polyplumb
OsmaGold
Speedfit
Equator
pipe
It is recommended that an Equator sleeve is used, although the sleeve relevant to
the pipe could be used.
Use an Equator or
Speedfit Sleeve.
Equator
socket
Use an Equator sleeve (other sleeves are shorter than the Equator sleeve and may
lead to problems if the pipe is curved adjacent to the joint).
Use an Equator sleeve.
(Speedfit sleeves are not
chamfered and could
damage the Equator O ring)
Use of Spigot Ended Fittings
Brass
Spigot
Ended
Fittings
Only use Equator spigots in Equator sockets, and do NOT use Equator spigots in other brands of sockets. (Each brand of
spigot has a grip ring groove which is located specifically for that particular joint style).
Plastic
Spigot
Ended
Fittings
Some other brands of spigots have a grip ring groove; do not use these in Equator Sockets.
Use of other brands of spigots which do not incorporate a metal support sleeve, are not recommended for jointing to
Equator sockets.
Connections to PVC & cPVC Solvent Welded Systems
Connections to existing PVC & cPVC pipework can only be achieved by using a suitable solvent weld x BSP adaptor, then use an Equator BSP
adaptor to connect to the thread.
Non-Standard UK Size Plastic Systems
Some plastic piping systems are designed as non-standard UK sizes such as 16mm, 20mm, 25mm, etc. Push-fit connections to these systems
using Equator should NOT be attempted.
