Operation
The AcquaSaver valve will always prioritise the use
of rainwater over mains water when rainwater is
available and will automatically switch to mains
water in the event of the rainwater tank running low
or an electrical failure.
When rainwater has been replenished, or power
has been restored to the pump, the AcquaSaver
valve will always automatically prioritise back to
rainwater.
The pump is only active when rainwater is being
drawn from the rainwater tank; it does not operate
when the AcquaSaver valve has switched to mains
water position.
The pump's controller will start and stop the pump
when it detects a demand, for example, flushing a
toilet.
The operating mechanism of the AcquaSaver valve
is a unique patent design. It works by hydraulic
water pressure created by the pump to close the
mains water inlet, ensuring an extremely reliable
mechanism using few moving parts, no electronic
components and no energy consumption.
Maintenance
The AcquaSaver valve does not require
maintenance; however, there are things you can do
to ensure its most reliable operation:
– Fit a Y-Strainer
– Clean your gutters
– Clean the inlet strainer on the rainwater tank
