Inlet

Our standard underdeck tank comes fitted with a 300mm leaf strainer inlet in the centre at one end of the tank. 

Outlet

A 25mm brass outlet is fitted at each end of the tank at a height of 43mm from the base of the tank.

Overflow

Outlets and overflows are sealed and will need to be drilled out by using a holesaw to your requirements.

Included with your tank purchase is a 25mm ball valve, leaf strainer (fitted) and Mozzie Stoppa (not fitted) connection to be fitted anywhere you like.
