$55.00 Add to cart

The StubGS01 Grate Seal® is a specially designed rubber, one-way valve that is easily retro-fitted into 4" or 100mm drains and floor wastes preventing sewer gases, airborne bacteria, soap suds, vermin and noise from making their way out of the drainage system into habitable areas. At only 120mm deep, it is perfect for installations where a more shallow Grate Seal® is required. 

As a Watermark® approved product, the one way valve does not restrict flow, and the flow rates achieved more than cope with the maximum allowable flows from plumbing fixtures such as showers. Unlike other products on the market, a water seal is not required for Grate Seal® to be 100% effective making Grate Seal® a permanent and maintenance free solution. 

 Grate Seal® is produced from an antimicrobial polymer compound making it durable and resistant to breaking down and allowing it to be used in a wide variety of applications, including the medical and commercial field. Grate Seal® is supplied at a low cost considering the problems that are resolved without having to remove or replace tiled surfaces.

This product is amazing, I tried a number of other products (and spent a lot of money) and found this is by far the best. Just purchased another one for a 50mm drain. Thank you, Ty
