$55.00 Add to cart

The GS01 Grate Seal® is a specially designed rubber, one-way valve that is easily retro-fitted into 4" or 100mm and 3" or 80mm 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.

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, concrete, waterproofing, etc. 

Simply cut along the marked line to convert from 4" or 100mm to 3" or 80mm (GS01 model only).

Attention Tony! Thank you for your help and prompt attention to my enquiry regarding the Grate Seal. The product has been received and was easily installed. What a great invention that immediately overcame a stinking problem that I had endured for quite some time. Kind regards.

Since moving into our brand new apartment only 5 months ago, we have had an unpleasant, smelly drain in the ensuite. Recently I heard a great ad on the radio which said that there was a simple and inexpensive product that would rid us of this unwanted odour. I jumped on the website which was very informative and short videos explained how easy it was to install the grate seal. It has totally solved our problem. Special thanks to Tony for providing an easy solution to our smelly drain and for his outstanding after sales service. I totally recommend this product!

My laundry floor waste in my unit kept on foaming up with suds. As soon as we installed Grate Seal, no more foaming suds! So easy and simple to install.

I have used this product in all my rental properties and my tenants couldn’t be happier with the results. NO MORE SMELLS!
