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
waterin 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 and
needs no maintenance or adjustment.
• RainBank is easy to install.
• RainBank does not require mains
water to be re-pumped 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.
