Using two inlet ports, the Drainwave® collects grey water from general household use (sink, shower, washing machine, etc) and combines this outside the house with black water from the toilet. The combined waste water leaves the Drainwave® and surges through the pipe network to the main sewer line to minimise blockages.

The Drainwave® provides to all water product companies, especially toilet manufacturers an ability to move to the next generation of water saving products - the worldwide future.

• No change to the users lifestyle or convenience.
• One moving part and little or no maintenance for the life of the product.
• Inexpensive to install and maintain.

Drainwave is watermarked under ATS 5200.499 – Technical Specification for plumbing and drainage products – inline sewer dosing device (SDU)
