The British greywater diverter
Designed to make every bath go further
Give every drop
a second life.
Most people are more comfortable watering the garden with clean drinking water than reusing bath or shower water, even though drinking water is the resource we should be trying to save.

Estimated litres reused
6,172,500litres reused per year
Over six million litres given a second life.
Based on historic Watertwo sales and current online orders, we estimate that Watertwo valves could be helping customers reuse over 6 million litres of water per year.
This estimate is based on 4,115 valves and a conservative figure of 1,500 litres per valve per year, allowing for seasonal use, wet weather and intermittent customer use.
A small intervention in a wasteful routine
Clean water arrives at your home, does one job, then disappears. Watertwo interrupts that story.
No app. No dashboard. Just a practical British-made idea you operate when the water is suitable for prompt garden reuse.
Three turns.
One better destination.
Watertwo fits to standard 40mm bath waste pipework and gives suitable water another way out.

Water worth using twice
Your garden already has a water source. It’s upstairs.
Useful through dry spells, hosepipe restrictions and ordinary weeks alike—especially for households watching a water meter.
