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

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.

protect from the weather

Don’t create air locks!

Fit isolation valves

prime pump before switching on
