Water Tank Outlet Fittings | Water Tank Connection Fittings
All Our Stainless Steel Water Tanks Come with Three Standard Inclusions. Upon ordering your tank(s) you will be asked to place on a diagram where you want the fittings located.
Rainwater Inlet
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 500mm). 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.
Mosquito-proof overflow
A 90mm or 100mm sized mosquito-proof overflow fitting at the top of the tank wall, directly under the lid.
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.
Ball value
A 25mm outlet fitting together with a tested ball valve which is placed at the bottom of the tank.
Additional Water Tank Fittings
Best practice for larger tanks is to also include a High suction (HS) fitting. This is a 50mm outlet and ball valve installed on the 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.
You may also wish to purchase a Bucket Height Tap for example, where the tap is placed high enough from the base, to allow gravity feed of water, into a bucket placed under the tap.

- 50 mm outlet male or female
