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.
4 m
5 m
5 m
100,000 Litres
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 most 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
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.

• RainBank
®
must be installed and serviced by a licensed plumber.
• Check with your local water authority on water restrictions when your rainwater tank is connected to mains water.
• Do not enter a empty rainwater tank - they may contain hazardous gases.
• Before installing RainBank
®
please read all instructions carefully as failures caused by incorrect installation are not covered under warranty.
• 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.
• The pumping of abrasive materials will damage the system and void the warranty.
• 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.
• Secure all openings to the rainwater tank and make sure the wiring, plumbing and the RainBank
®
unit are protected from access by children and pets.
• Water freezing inside the RainBank ® will damage the unit. Locate your
RainBank
®
and pump so that they are not susceptible to freezing.
• 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.
• Over time the relevant position of the home or RainBank ® and the rainwater tank may change slightly. In order to reduce the stresses on pipework such movement may result in, it is recommended that a length of flexible pipework from pump to RainBank
®
be installed. This pipework can be a braided hose or polythene pipe or similar.
• Limit mains water pressure to 900kPa.
• Under Australian Standard 3500 collecting/storing rainwater in a buried tank is considered a medium level hazard. Even though RainBank
®
has a built-in dual check back flow valve, you may be required to fit additional backflow protection valves to satisfy this requirement – check with your local council as to their guidelines on rainwater tank installation and backflow prevention.
• 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’.
• 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.
• There is no need for a separate float switch as this comes attached to the submersible pump and does not plug into the RainBank® unit.
InStALLAtIon tIPS
other things we recommend to maximise the performance and serviceability of your RainBank ® .
• Install cabinet on a solid, well protected wall (this will reduce noise and pipe stress).
• Fit first flush devices to all down pipes to ensure clean water inside the tank
(dirty tank water can stain toilets & clothes).
• 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.
• Clear swarf from all pipes and holes drilled into the tank (swarf can block valves,
RainBank
®
and toilet valves).
• Check with local council plumbing teams for backflow requirements.
• Keep pipe work well braced as vibrations can become noisy.
• Fill rainwater tank above float switch with garden hose to check system.
• Make sure pump is full of water (primed) before leaving site. Flush all air out of system by running pump with an outlet downstream open.
• Advise the customer to clean filters inside cabinet regularly.

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 feeds the washing machine or flushes the toilet. Mains water should flow normally. The pump should
not
turn on. The
‘status’
light should glow
‘red’
to indicate that mains water is being used. When this is completed turn off tap.
2. Fill the rainwater tank with sufficient water to activate the pump.
3. Check that the pump is sitting in sufficient water (above the level of the float) to self prime and let air out without causing equipment damage ensure:
• All taps connected to the rainwater system are turned on.
• Toilets connected to the system are flushed so that the cistern fills and any air is cleared from the line.
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. The
‘status’
light will now glow
‘green’
.
5. Check for leaks around RainBank
®
, the pump, pipework and fittings.

MAIntAInInG RAInBAnk
®
RainBank ® does not need maintenance but there are things you can do to ensure its most reliable operation.
• Fit a “first flush” system that ensures the first run of dirty rainwater does not go into the tank.
• Clean your gutters and first flush devices ‘Y’ strainers and filter regularly.
• Remove branches that over hang your roof.
• Have a strainer fitted to your rainwater tank inlet and regularly check this for leaves and twigs, etc.
• You should also check for debris in the bottom of your tank a few times a year and clean this out if necessary. A first flush system will greatly reduce the need for this action.
• Davey pump motors are fitted with an automatic thermal overload switch that stops the motor if the motor gets too hot to avoid damaging it. This automatically re-starts the motor when the temperature within the pump has dropped to a safe level. Constant tripping of this switch indicates a problem e.g. Low voltage at pump, etc.
• This automatic thermal overload switch can start the pump without warning.
Always disconnect the controller and/or pump motor from the electrical supply before maintenance or repairs.
• Care should also be taken when servicing or disassembling pump to avoid injury from hot pressurised water. Unplug the pump, relieve the pressure by opening a tap on the discharge side of the pump and allow any hot water to cool before attempting to dismantle.
• Do not use petroleum based fluids or solvents (e.g. oils, kerosene, turpentine, thinners, etc on the plastic or seal components).
• Do not use hydrocarbon based or propelled sprays around the electrical components of the controller.
• During servicing use only approved non petrochemical based o-ring and gasket lubrication. If unsure consult your Davey dealer for advice.
