3. Check in the mouth of the fitting that
the ‘O’-ring, nylon washer and collet
are in position as shown in Fig. 13.
4. Push the pipe firmly into the fitting,
until pencil mark is level with the top
of the collet and the pipe stop
resistance is felt. Pull on the pipe to
check it is secure and correctly fitted
5. To release the joint, push pipe firmly into the fitting, hold the collet down and gently
remove pipe. If the system has been filled with water care should be taken to isolate
the pump and towels used to absorb spilled water.
If you have any concern either about using push-in fittings or should the joint leak on final
test, isolate the water supplies and contact Pump Assist on 0844 98 000 97.
Hose to pipework (Release and connection of push-in connectors)
1. The hoses are fitted with plastic push-in connectors, which must only be connected
with the following:
a) 15 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3.
b) 15 mm plastic pipe to BS 7291 part 1 and part 2 (Table 1), or part 3 (Table 1) plus
internal support sleeve*.
* The internal bore of the plastic pipe must be supported against collapse with the
pipe manufacturers recommended support sleeve (pipe insert).
c) Appropriate plumbing fitting that provides a leak tight connection.
Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 12) and cut the pipe square, removing all burrs and sharp
edges to prevent damage to the sealing ‘O’-ring.
2. Prior to inserting pipe into fitting, mark the insert
depth on the wall of the pipe with a soft pencil at
a distance of 31 mm from the end to be inserted
(Fig. 12).
