General Pipe Cleaners 4FH Flood Guard, Stainless Steel, For: 4 in Float Model

Flood guard prevents basement flooding. It operates like a check valve to seal off water back-up caused by overloaded sewers. The flood guard can be installed in minutes. A screwdriver and a couple of minutes are all you need to install a flood guard. Once in place, it can prevent property damage and a very messy clean-up job. For extreme, extended pressure (for instance, where home- made seals have popped out of the line,) we recommend our standpipe models. The 4 in standpipe flood guard is threaded to receive 1-1/2 in IPS pipe. On the 3 in model, the pipe is slipped through the rubber gasket before the screws are fully tightened. Gaskets are made of molded rubber and all metal parts are plated or stainless steel.
