How Watertwo works
One simple valve.
Two routes for water.
Watertwo is fitted to suitable external bath or shower waste pipework. You choose whether the water continues to the drain or is diverted towards your garden.

The basic idea
Drain when you need to. Divert when the water is suitable.
Normal drain route
Leave unsuitable water on its normal route to the drain—for example when household products or circumstances make garden reuse inappropriate.
Garden route
Operate the valve to direct suitable bath or shower water through its outlet towards a water butt or suitable irrigation arrangement.

From bathroom to garden
Bathe. Divert. Water.
1
Use the bath or shower
Use suitable products and decide whether that water is appropriate for prompt garden reuse.
2
Operate the diverter
The Watertwo valve is operated from an accessible position using its pull cords.
3
Direct the outlet
A suitable hose carries the diverted water towards your chosen water butt or irrigation arrangement.
Why reuse water?
Make useful water go further
Available regularly
Bath and shower water is generated throughout the year, not only when it rains or during a hosepipe ban.
Useful for the garden
Suitable water can be directed where it is useful instead of immediately entering the drainage system.
Especially relevant on a meter
Reusing suitable water can help metered households get more value from water they have already paid for.
Responsible greywater use
Suitable water, used promptly
Greywater is not drinking water. What it contains, where it is used and how long it is stored all matter.
The finished guidance section will cover suitable household products, hygiene, plants and soil, storage limitations, irrigation methods and current restrictions. Until then, avoid unsupported assumptions and use the normal drain route whenever the water is unsuitable.
- Never treat greywater as drinking water
- Reuse suitable water promptly
- Consider soaps and bath products
- Follow current guidance and restrictions
Before you order
Will it fit your home?
The current valve is intended for suitable 40mm ABS waste pipe. Check the pipe size, access and outlet route before cutting anything.
