What's in
your water?
You hear about water problems.
But nobody tests at your tap. We do.
“I just assumed our water was fine. I'd never even thought to question it.”
New Forest parent
“We had a filter fitted years ago. I had no idea whether it was actually doing anything.”
Hampshire homeowner
“I knew about lead pipes in the news. I didn't think it applied to our house.”
New Forest parent
A lab-accredited test. At your kitchen tap.
A test kit arrives by post. Fill the bottle at your kitchen tap, send it back, and receive lab-accredited results. We test 9 parameters including lead, copper, nitrate, iron, manganese, nitrite, pH, hardness, and total dissolved solids.
You get quantitative readings - actual numbers, not just positive or negative.
Every test builds a structured exposure record for your home - timestamped, versioned, and yours to keep. It becomes your household's baseline.
Three steps. No appointments.
One clear answer.

Family-run. New Forest-based. Built on something we couldn't find anywhere else.
WaterGraph started because we wanted to test our own water - and found there was no simple, affordable way to do it. No one testing at the tap. No ongoing monitoring. No clear answers.
So we built it. We're a family-run company based in the New Forest, and we believe everyone deserves to know what's in their water - not just once, but over time.
We're not a lab. We're not a utility. We're your neighbours, building the infrastructure that should have existed already.
Every home that tests adds to a shared picture of your watershed. Your data helps your neighbours understand their exposure. Their data helps you.
The more households that participate, the more credible the scores, the harder it is for contamination to go unnoticed, and the more useful the map becomes for everyone - including the institutions that should be paying attention.
Your individual data stays private. The map shows anonymised, aggregate exposure patterns at watershed level.
£30. Delivered to your door. Lab-accredited results.
