test the operation of rainBank ® .
1. With the mains connected and the rainwater tank empty turn on one of
the taps in the laundry that feed the washing machine or flush the toilet.
Mains water should flow normally. The pump should not turn on. When
this is completed turn off tap.
2. Fill the rainwater tank with sufficient water to activate or cover the float
switch.
3. check that the pump is correctly primed and there are no air locks that
will interfere with its operation as per the davey instructions. this is
essential for the proper operation of the unit. see the instructions on how
to do this for all types of davey pump in the Priming section on page 26.
4. Turn on a tap or flush a toilet in the rainwater system. The pump should
run and deliver rainwater. allow to run for several minutes to clear air
from pipes.
5. Remove the float switch connection from the RainBank ® – this should
stop the pump and confirms that the float switch and power connections
have been made correctly - refit the float switch connection. Press the
manual override button to operate the pump if needed.
6. check for leaks around rainBank ® , the pump, pipework and fittings.
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.
IMPORTANT: It is highly recommended that an isolation valve be fitted to
where the mains water enters RainBank ® and between the pump and the
rainwater tank. This facilitates easy removal of the unit if required without
turning off the household water or losing stored rainwater.
NOTE: Do not instal additional suction check valves on RainBank ® systems
except where a foot valve is required (eg. suction lift installations). In the
case of suction lifts, to allow for the correct operation of your RainBank
®
and for movement of the tank and pump which may occur over time, the
suction pipe must have a length of flexible suction hose from pump to
top of tank. This hose can be braided hose, reinforced suction hose or
polythene pipe at least 1 metre in length.
