congratulations on your purchase of
a high quality australian made Davey
rainbank ® automatic water controller.
rainbank ® is patented and has been fitted
to thousands of homes.
• rainbank ® allows you to use water
from your rainwater tank for your
toilet, washing machine or garden
whenever there is water in the tank.
• If the tank water is exhausted
rainbank ® automatically and
seamlessly switches you over to mains
water.
• rainbank ® has an in-built “dual
check valve” for low hazard back flow
prevention.
RainBank ® can save up to 40% of
your home’s usage of mains water,
which could be up to 100,000 litres
of water a year.
Your actual savings depend on your roof
catchment area, rainfall and the size of
your tank.
RainBank ® may allow you to claim
tank rebates (when installed on
existing homes). Check with your
local water authority.
In some areas of australia, having a
rainbank ® and using rainwater for
your toilet and washing machine allows
you to claim tank rebates paid by state
governments and some councils.
RainBank ® is energy efficient and
cheap to run.
because rainbank ® only works when it is
needed it uses very little energy.
the daily power used to run a rainbank ®
and pump system supplying two toilets in
a three person dwelling is equivalent to:
• a reverse cycle air conditioner for
3 minutes
• a clothes dryer for 3 minutes
• a washing machine for 10 minutes
• a tV or pc for 30 minutes
about raInbank ®
the easY WaY to saVe Water pluMbers tIps
1. Install pump on a level, solid, well drained site (this will reduce noise and pipe
stress).
2. Fit first flush devices to all down pipes to ensure clean water inside the tank (dirty
tank water can stain toilets & clothes).
3. clear swarf from all pipes and holes drilled into the tank (swarf can block valves,
rainbank ® and toilet valves). Fit a 200 micron ‘Y’ strainer before the pump or
between the pump and rainbank.
4. Fit a stop valve on mains water line before rainbank (makes servicing easier).
5. Fit a stop valve between pump and tank outlet (makes servicing easier).
6. check with local council plumbing teams for backflow requirements.
7. keep pipe work well braced as vibrations can become noisy.
8. Fill rainwater tank above float switch with garden hose to check system.
9. Make sure pump is full of water (primed) before leaving site. Flush all air outof
system by running pump with an outlet downstream open.
