PIPE CONNECTIONS
For best performance use P.V.c. or
polythene pipes at least the same
diameter as the pump’s inlet and
delivery outlet openings. larger
diameter pipe may be used to
minimise resistance to flow when
pumping longer distances.
use unions at pipe connections to enable easy
removal and servicing. Use sufficient tape to ensure
airtight seal and hand
tighten only. to prevent strain on pump threads
always support heavy inlet and outlet pipes. If
there is a likelihood the water supply may contain
solid particles such as pieces of plant or vegetable
matter, a filter should be installed before the pump to avoid blocking of
water ways. lay suction pipe at a constant gradient to avoid air pockets
which may reduce pump efficiency.
use unions at pipe connections to enable easy removal and servicing.
Use sufficient tape to ensure airtight seal and do not over tighten. To
prevent strain on unit threads always support heavy inlet and outlet pipes.
NOTE: Suction leaks are the largest cause of poor pump performance and
are difficult to detect. Ensure all connections are completely sealed using
thread tape only.
Do not use pipe thread sealing compounds on any part of this pump. ONLY
use Teflon sealing tape.
NOTE: Prior to installation remove the transport plugs from the inlet, outlet
and lamp end cap.
Do not use pipe thread sealing compounds (especially hemp) on any part
of this unit. ONLY use Teflon sealing tape.
RainBank ® controllers can only be connected to mains water, by a qualified
