The Floor Gap

Created to alleviate the problem of sewage or drain water backflow into a water softener.

Floor Gap

We started working with water softeners in 1979.  We never could find a great solution for an air gap for the floor drain, so we built one.  The purpose of the air gap is to ensure that there will never be any back flow of sewage or drain water sucked into your water softener.

Introducing the Splash Guard

The Splash Guard is a custom designed ring that slips inside any existing Floor Gap and is meant to be attached directly onto the drain to reduce the splashing that occurs when the water Softener runs its regeneration cycle.
