100,000 Litres

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 Australian 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.

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

HOW RAINBANK WORKS

1. When there is demand for water

from your toilet, washing machine or

garden tap, RainBank senses

this demand and checks the level of

water in the rainwater tank.

Note: demand must be greater than

1.5 litres per minute or mains water

will be delivered.

2. If there is rainwater in the tank

RainBank switches on the pump.

The pressure of the pump is

sufﬁcient to overcome the pressure of

the mains water inside RainBank

and this moves a plunger and allows

the rainwater to ﬂow.

Note: mains water pressure is not

restricted.

3. When there is no longer a demand for

water, RainBank detects that water

has ceased to move inside the pipes,

switches off the pump and waits for

another water demand.

4. If RainBank senses a water

demand and detects insufﬁcient water

in the rainwater tank it will

automatically allow the mains water

to ﬂow.

5. If there is a power failure during a

demand for water RainBank will

automatically supply the mains

water as backup.

What are the advantages of

RainBank over conventional

air-gap systems?

• RainBank is totally hands off for

your customer and needs no

maintenance or adjustment.

• RainBank is easy to install.

• RainBank does not require mains

water to be re-pressurised and

therefore saves energy.

• RainBank is WaterMark approved

- this means plumbing inspections

will be approved & your plumbers

insurance should cover installation

faults.

• RainBank will provide mains water

as backup when:

- there is no rainwater

- there is no electricity to run pump

- the pump has been removed for

servicing. Air-gap systems rely on

pumps to pressurise all water

and do not function without

them.

BEFORE YOU START

IMPORTANT:

• Because it involves mains water,

RainBank may only be legally

installed by a licensed plumber.

Ensure mains water pressure is

limited to 600kPa.

• If you are in doubt about any aspect

of your RainBank kit’s suitability,

check with your Davey Dealer. For

help in locating your closet dealer

call the appropriate Davey Customer

Service Centre listed on the back of

this booklet.

• RainBank is designed to handle

clean rainwater and mains water. It

should not be used to interconnect as

part of a bore water, dam water,

grey water, stormwater or recycled

water system.

Other things we recommend to

maximise the performance and

serviceability of your RainBank.

• Fit a ﬁrst ﬂush system if possible to

divert the initial run of water from the

roof that may contain dirt and

pollutants.

• Fit a strainer to the top of your tank

inlet to stop leaves entering the

system.

• Use at least 20mm or 3 ⁄4 inch

plumbing to and from RainBank to

reduce the effect of pipe friction.

Galvanised pipe not recommended.

• Clean ﬁlters inside cabinet regularly.

• While RainBank does have an in-built

DUAL CHECK back ﬂow prevention

valve, some water authorities require

an additional external back ﬂow

valve to be plumbed into the mains

water delivery line, to prevent any

possible contamination of mains

water by rainwater, particularly if the

tank is partially or fully submerged.

Check with your local water authority

for their plumbing guidelines on

rainwater tanks.

INSTALLATION INSTRUCTIONS

Things you should be aware of:

• Before installing RainBank please

read all instructions carefully as

failures caused by incorrect

installation are not covered under

warranty.

• The pumping of abrasive materials

will damage the system and void the

warranty.

• Some insects such as small ants ﬁnd

electrical devices attractive for

various reasons. If your controller or

pump is susceptible to insect

infestation you should implement a

suitable pest control plan.

• Limit mains water pressure to

600kPa.

• All pipe work and ﬁttings should be

labelled in accordance with local

standards such as Australian

Standard AS/NZS 3500. This standard

requires that all pipework containing

rainwater is marked with green

‘rainwater’ tape or stickers at 1

meter intervals and every outlet that

may deliver rainwater is to be

permanently signed with ‘Rain Water’

signage or a green tap marked ‘RW’.

• Mains electrical connections and

checks must be made by a qualiﬁed

electrician and comply with applicable

local standards. The 12 volt

connections need not be carried out

by a qualiﬁed electrician, but should

be done in compliance with applicable

standards.

• In accordance with AS/NZS

60335.2.41 we are obliged to inform

you that this controller and any pump

controlled by it is not to be used by

children or inﬁrm persons and must

not be used as a toy by children.

• Davey recommends a 2mm hole in

the pipe work just above the pump

outlet to clear air from the pipe work.

NOTE: Please be advised that a

disconnection incorporated in

the ﬁxed wiring is to be provided.

1. Run mains water plumbing, rainwater

plumbing and power supply through

external wall according to the following

dimensions.

2. Cut ø365-375 hole in tank top. Ensure

that the hole position coincides with

a clear area for pump to reside on

tank ﬂoor. Pump should be placed

in a position on tank ﬂoor which has

adequate dimensions so as not to

restrict the movement of the ﬂoat

switch.

3. Cut pump stand pipe so that pipe end

is approximately 50mm from tank top

in installed position.

4. Connect a cable or chain to the

submersible pump – so that it can

be lowered into the rainwater tank –

important – handling the pump

by straining the power lead will

damage the pumps water seals

and cause premature failure not

covered by warranty.

5. Connect PVC (DN25) to the pump

outlet and lower assembly into the

rainwater tank. Cable tie pump power

lead to the pipework.

6. Cable tie power lead from pump to

pipework and bundle excess cable to

base of the Evolution MkII.

7. Arrange pump so that stand pipe

aligns with Evolution MkII inlet at

base of primary ﬁlter chamber.

8. Remove primary ﬁlter lid and ﬁlter

from the Evolution MkII housing to

expose four Phillips head screws in

chamber base.

9. Fasten Evolution MkII to tank top

using self drilling sheet metal screws

using the 7 locations provided.

10. Fasten the four screws in the base

of the primary chamber in order to

clamp stand pipe in position. Ensure

screws are tight by repeating the

tightening pattern.

11. Reinstall the primary ﬁlter and lid.

12. Connect Mains and outlet plumbing

to Evolution MkII ensuring correct

orientation. If plumbing ﬁt out is

incorrect, the use of ﬂexible hoses

is suggested to connect to the

Evolution MkII.

13. Open Mains water valve and check

for leaks.

14. Switch on power to RainBank and

check for ﬂashing green light – light

will ﬂash ten times as it boots up.

15. Open a tap downstream of RainBank

to clear lines of air and check for

leaks. Requires a ﬂow rate of at least

10 litres in 1 minute to expel air.

16. Press manual override button on top

of RainBank to start pump and ﬂush

air from rainwater lines. There must

be rainwater inside the tank – this is

an important part of commissioning

the system.

17. Close tap and check for leaks.
