Hose to Pipework
1. Stuart Turner recommend only the use of their 22 mm flexible hoses.
The hoses are fitted with plastic push-in connectors, which must only be connected
with the following:
a) 22 mm diameter copper pipe to BS EN 1057 - R250 (half hard) - Table 3.
b) 22 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.
STEP 4 PUMP CONNECTIONS (Release and connection of push-in connectors)
WARNINGS:
 Do not use stainless steel, chrome or nickel plated pipe with Stuart
Turner push-in plumbing connections.
 Do not introduce solder flux into the joint or surrounding area as
connectors will be attacked and may fail.
All solder joints should be completed and flux residues removed
before final connection to push in connections, either on flexible hose
or pump head.

Do not allow contact with oil or cellulose based paints, paint thinners
or strippers, acid based descalents or aggressive cleaning agents.
Disconnection
To break the joint, push the pipe into fitting, hold collet down and gently remove pipe by
pulling out of collet (Fig. 13). If the system has been filled with water, care should be taken
to isolate the pump and towels used to absorb spilled water.
Hose to Pump
The pump inlet and outlet ports have factory assembled fittings which are specifically
designed for connection to the G ¾ female running nuts on the flexible hoses. The hose
end is fitted with a rubber sealing washer which is held captive within the nut assembly.
Locate the hose into position and screw the nut fully onto the fitting by hand. finally nip
tight with a spanner (4/5 Nm) for a water tight seal
(do not overtighten).

Note: When tightening or loosening the
hose nut assembly, the anti-rotation
flats provided on the inlet and outlet
fittings should be used for placement of
a second spanner as shown. This is to
prevent complete assembly rotation.
It may be necessary to partially rotate
the reed switch clamp assembly on the
outlet fitting to avoid damage during
placement of the second spanner.
