150mm (6") Stainless Steel Tiles with Non-Return Valves


The conventional floor drain was historically used for drainage during the washing of floors, the emptying of old mop buckets and gravity-drained washing machines. Presently with dry floor-cleaning techniques and washing machines that pump waste water directly into the drainage system, their role has changed. Today, they primarily serve as emergency drains. Meaning they drain water that results from a water emergency due to an overflow, a blockage or water appliance malfunction. However, emergency drains are not used frequently and the requirement to use a water seal severely restricts their functionality.

The Problem

Conventional floor drains adopting a water or liquid seal all tend to suffer from the same generic problems; siphoning, odours, evaporation, blockages and pest entry. This poses a huge hygiene problem and can leave a negative perception in the open spaces concerned.

The Solution

The Hygiene Drain is a simple, multi-patented and cost effective solution for both new build and retrofit applications. Hygiene Drain is an accessible, completely closed system and takes away the need for utilising liquid seals. It simplifies the installation process and provides a hygiene seal between the open space and the drainage system.

The key benefits of The Hygiene Drain are as follows:

  • Tile can be fitted into a new or existing floor drain
  • The tile outlet will go inside 110mm/4" Pipe
  • Non Return Valve prevents sewer gases entering the rooms where there is back pressures and odours from pipes.
  • The non return valve will ensure retention of a seal even under extreme symphonic conditions
  • Tiles are manufactured from Heavy Duty Stainless Steel (austenitic 1.4301SS)
  • Tiles are fitted with a removable stainless steel mesh filter & valve for cleaning purposes and maintaining pipe work
  • Two types of valve available. Spring Loaded Rubber & Silicone Valve Seals
  • Available in either Brushed or Polished finish

How it Works

The functionality of The Hygiene Drain is simple and ingenious. The Hygiene Drain sits watertight inside the drain. It's chosen seal stays open when water is flowing, but closes when the water stops. When the seal is closed, it successfully resists any emission of sewer gases, even under extreme symphonic conditions.

Installation Procedures

Whilst on each installation the installer many encounter a few variables, the generic process is as follows:

  • Identify if the plate is suitable when comparing to the existing drain
  • Remove the old floor drain
  • Cut down white extension piece to appropriate size
  • Seal to floor drain with appropriate sealant
  • Fit floor drain and extension into existing void
  • Using appropriate sealant (recommended use of quick dry cement) to fix floor drain in position
  • Cordon off area to allow for area to dry
  • Flow test

Recommended Routine Maintenance

As the new Hygiene Drain no longer relies on a water seal to maintain its integrity, there is very little(if any) reactive maintenance required.

Recommended planned preventative maintenance is as follows:

  • On a monthly basis, check the grate and valve seals
  • Clean these parts if necessary
  • Replace seals every 6-12 months where heavy detergents are used
