These Aqua Source Aquadrift 4″ Bottom Drains are perfect for gravity fed installations in fibreglassed ponds. The Aquadrift is precision machine cut to the highest standard, providing a bottom drain you can rely on.

Suitable for direct connection to 4″ pressure pipe or standard 110mm waste pipe when used with suitable connectors. The Aquadrift comes fitted with a separate 1" pressure pipe air connection which allows air to enter the drain independently from the water pipe outlet. The separate connection means the unit can be installed without the use of air hose to the bottom drain, instead simply use the appropriate connector after your air pump.

The membrane and backing plate on the Aquadrift Bottom Drain fits into a recess in the specially manufactured rubber dome . The recess in the Aquadrift Bottom Drain prevents the membrane from becoming detached. The complete assembly is secured to the Aquadrift bottom drain by means of a threaded stem, which also provides the air inlet.
