How Flood Guard Drain Sealers Work

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. The Flood-Guard float then rises to seal off the drain opening until the water recedes.


A screwdriver and a couple of minutes are all you need to install a Flood-Guard. Remove the strainer or plug cover if present and push flood guard directly into pipe (oil or grease can be used to assist). Be sure float is screwed on tightly. Once in place, it can prevent property damage and a very messy clean-up job. Please note: the flood guard should be cleaned regularly to make sure that float moves freely.

For extreme, extended pressure (for instance, where home-made seals have popped out of the line,) we can also supply standpipe models. Please call for details
