Signs Your Premises Need a One-Way Water Valve
If your washrooms experience any of the following problems, Grate SealⓇ can provide immediate results:
- Airborne bacteria that start in and spread from biofilm that grows on the underside of the grate in basin wastes, between the water trap seal and also in floor wastes.
- Cross-contamination issues.
- Vermin, such as rats, mice, and cockroaches entering the premises through floor wastes.
- Regular build-up of mould.
- Strong odours.
- Complaints from staff or the public regarding the state and smell of your washrooms.
- Ongoing maintenance costs.

How Grate SealⓇ Works
The product is a single-unit seal, which is inserted between the basin and the basin waste to prevent any aerosol bacteria and biofilm from entering the basin’s wash area.

Combining Grate SealⓇ with Sterisan Basins

Gentec one-way valves are fully compatible with this sink, thus offering a two-pronged, thorough solution to enhancing infection prevention and control.
