Pipework Connections (Hot)
When a hot water cylinder or storage tank is used, ensure the pipework size from the
cold water storage to the hot water storage is of adequate size and a minimum of 28 mm.
The pump must be supplied with a dedicated feed direct from the hot water
cylinder or storage tank.
Ensure the pipework size from the hot water storage tank to the pump is of adequate
size and a minimum of 28 mm. The supply must be air free and connection to the cylinder
can be via an Essex flange, or by one of the following methods shown in Fig. 8.
When the method of connection is to be made via the expansion pipe, the cold water
cistern should be at least 1.5 metres above the top of the hot water cylinder.
NOTE: Care should be taken in the design of pipework runs, to minimise the risk of air
locks in pipework.
Pipework Connections (Connection between pump and shower valves or taps)
This should run as far as possible in 22 mm copper tube. Any bend requirements should
be achieved by hand drawing the tube or by use of the appropriate bend fittings. Pipework
should only be reduced to 15 mm copper if necessary when entering the terminal fittings.
By this method the maximum performance of the pump will be maintained. All pipework
should be securely clipped.

(Release And Connection Of Push-in Connectors)
WARNINGS: (Push-in Connectors)
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.
