3.12 Hose to pipework:
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 fittings that are compatible and will provide a water
tight connection.
Ensure the pipe is free from all score marks and deformities in the area of the
insertion depth (Fig. 9) 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 insertion depth on the wall of the
pipe with a soft pencil at a distance of
31 mm from the end to be inserted
(Fig. 9).
3. Check in the mouth of the
fitting that the ‘O’-ring, nylon
washer and collet are in
position as shown in Fig. 10.
4. Push pipe firmly into fitting,
until pencil mark is level with
the top of the collet and the
pipe stop resistance is felt.
Pull on pipe to check it is
secure and correctly fitted.
5. To release the joint, push pipe firmly into fitting, hold collet down and gently
remove pipe. If the system has been filled with water care should be taken to
isolate pump and towels used to absorb spilled water.
