and 40 to 50 mm thick.

Pipe connection to hot-water cylinder
Use 22 mm pipes to and from the pump.
• The expansion pipe from the hot-water cylinder should always
rise in order to prevent trapped air.
• The outlet pipe from the pump to the shower valve should rise,
where possible, to prevent trapped air.
• Pipes from the pump to the shower valve should go up and
over, rather than under floor.
• Do not fit any other outlets in the inlet pipes to the pump. See
fig. 12.
• Use dedicated supplies to hot and cold water.
• Avoid blanked-off pipes.
• Avoid restrictions in the flexible hoses.
• Secure down all pipes to minimise noise and vibration.
