Rainwater enters the tank through the INLET on the lid of the water tank.
Typically the inlet fits a 400mm diameter strainer (other sizes include
300mm and 400mm).
Select Water Tanks supplies a 400mm
inlet with strainer and light guard as
standard. The light guard prevents
your rainwater from exposure to Ultra
Violet light which encourages algae
Each water tank requires an OVERFLOW connection point installed at the
top of the wall, directly under the lid.
Water tanks with a capacity of 10,000 or less
are fitted with a 90mm PVC corrugated overflow body. Larger tanks are fitted with a
100mm overflow body.
A mosquito proof gauze is supplied with each
overflow. This also prevents frogs, toads and
vermin from entering the water tank.
Each water tank is fitted with a 25MM OUTLET and ball valve at the base of
the tank.
Best practice for larger tanks is to also include a HIGH SUCTION FITTING.
This is a 50mm outlet and ball valve installed another corrugation above.
This allows for efficient water balancing when other tanks are connected.
The HS Fitting also protects the pumps and internal water appliances as it
draws only clean water from above the sludge / anaerobic level.
