General Wire S-4FH Drain Standpipe Flood Guard, 4"
Flood-Guard™ operates like a check valve to seal off water back- up caused by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. For extreme, extended pressure (for instance, where home-made seals have popped out of the line), we recommend our standpipe models. The 4" Standpipe Flood-Guard is threaded to receive 1-1/2" IPS pipe.
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.
