Flood Guard - Help Prevent Basement Flooding

4" Stand Pipe Model
(3" model is not threaded)

Flood-Guard operates like a check valve to seal off water back-up by overloaded sewers. Water flows normally through the drain until the sewer begins to back up. Then the Flood-Guard ("Float Model") float 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. Once in place, it helps prevent property damage and a very messy clean-up job.

The 4" Stand Pipe Flood-Guard is threaded to receive 1-1/2" IPS pipe. On the 3" 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.

Frequently Asked Questions

Q. "My floor drain has an inside diameter of 2 3/4 inches. Will any of these Flood Guards work in my pipe?"
A. The manufacturer currently only makes FloodGuards for the sizes shown, so for your size of pipe, none of these would work. The 2" model would be too small and the 3" model would be too big.

Q. "Will these Flood-Guards completely prevent flooding?"
A. Due to the nature of floor drains the float style Flood-Guard can become blocked open by debris, allowing back-up water to enter; they must be checked periodically. There is a limit to how much flooding these can help to prevent, based on various circumstances such as; head pressure, nearby drains, outlets, sinks, and many other things that we aren't able to easily list. This device may will also mask other important plumbing issues that should be taken care of, so do be careful. Also, be sure to inspect the Flood-Guard regularly as all mechanical devices will eventually fail; proper maintenance and inspections can help mitigate any failure.
