INSTALLATION OF
SUBMERSIBLE PUMPS
1. Use Teflon tape on the pipe
to pump connection.
2. Secure the power cable to the
delivery pipe with cable ties.
3. Place pump into tank.
4. Davey recommends the fitting of
floating inlets to submersible pumps
to minimise any possibility of sludge
intake. Part number to suit pump
D42A/B is FI-42.

IMPORTANT
Do not pull on power lead. Fit a
rope to handle for lowering and
raising pump.
Submersible pumps inside tank.
Provided the pump is sitting in sufficient
water the pump will self prime and push
air out of the taps and appliances that are
used at the other end. To let this air out
without causing damage it is important
that:
• All taps connected to the rainwater
system are turned on
• Toilets connected to the system are
flushed so the cistern fills and any air
is cleared from the line.
