Additional 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.
