The Fernco Grate Seal is a specially designed, one-way rubber valve that fits straight into an existing waste outlet.
Once the valve is fitted it will prevent hazardous sewer gasses, airborne bacteria, soap suds, vermin and noise from making their way out of the drainage system and into habitable areas.
The one-way valve, does not restrict flow through the drainage system, the flow rates achieved by the Grate Seal can easily cope with the maximum allowable flows from plumbing fixtures.
