3. the switch will not work properly if it
is not properly orientated. Make
sure the word “up” is seen at the very
end of the switch body. now tighten
the compression nut to expand the
seal (as shown below).
4. ensure that the switch is still correctly
orientated. With the word “up”
visible, screw on and tighten the
sealing nut to finish the installation of
the float switch.
STEP 4 - CHECK PIPE WORK
Make sure the final assembled position
of your rainbank
®
will align well with the
mains and rainwater pipe.
the pump and rainbank
®
should be
assembled so that the mains water
supply to the unit and rainwater outlet to
toilets and laundry connect easily to the
plumbing on the same level.
STEP 5 - CONNECT PUMP TO
RAINBANK
®
connect your pump to the rainbank
®
1. screw rotary coupling into outlet of
pump (teflon tape not required).
STEP 6 - CONNECT PIPES
connect the rainbank
®
to the mains water
and delivery pipe plumbing.
IMPORTANT
• to allow easy connection it is strongly
recommended that you have flexible
copper pipes that allow some
movement so that they can line
up exactly with the mains water and
rainwater outlet. these pipes must be
3 ⁄4 inch in diameter.

Tighten Compression Nut
bellow deforms
inside tank
maximum tank wall thickness of
25mm. It is not suitable for concrete
or very thick plastic walled tanks.
there is an alternative float switch
that can be lowered into the top of
these types of tanks (Davey part
number 13961).
Work out the correct position for
the hole for the float switch. With a
corrugated profile tank wall this is
on the upper flat section of the profile
as shown below.
Work out the correct location of the float
switch relative to the pump outlet.
the float switch location should also be:
• at least 40mm above the pump inlet.
• placed away from the rainwater entry
into the tank so that the incoming flow
does not interfere with the operation
of the switch.
before cutting the hole check again
that the 5m lead from the float switch
will reach the rainbank
®
and plug
comfortably into it.
1. Drill a 22mm hole in the side of the
tank in the correct position. a spade
drill is the best tool for this job.
ensure all swarf is removed from the
hole. If installing the switch in a
corrugated tank you should make sure
that it is installed on the flat section
between the radii as shown below.
2. ensure the compression nut is
loosened so that the sealing grommet
is not expanded. remove the sealing
nut and insert the switch into the hole
as below.
Centre hole on flat section of profile
Diameter of hole must be 22mm.
