GrateTrench™ Bulkhead Floor Drain

Odorless Floor Drain

GrateTrench™ has a unique valve system that opens automatically to let water in and closes when water is not present. Only two teaspoons of water is needed to open the drain valve. A closed valve system will not allow odors from stagnant water to rise and permeate the home. GrateTrench™ closed valve system also minimizes entry of harmful radon gases.

GrateTrench™ can be connected to any sub-floor drainage system or sump-liner.
