What are the signs of a water mains leak?
A meter turning with every tap off, rising bills or wet ground can indicate a leak. ADI Leak Detection Rhoose locates and marks the leak before digging begins.
A supply pipe leak is underground, so the signs below are usually all you see of it:
- The meter dial moves when every tap and appliance in the house is off
- A Dŵr Cymru Welsh Water bill that has climbed with no change in how much water you use
- Pressure that drops away when more than one outlet runs
- Wet ground, sinking block paving or a patch of lawn that stays green in July
- A Dŵr Cymru Welsh Water leak notification letter through the door
If the water is going from the garden watering pipes, irrigation leak detection tests those. A falling pool level calls for swimming pool leak detection to test the pool shell and circulation pipework.
Where do water mains leaks occur in Rhoose?
Water mains leak detection in Rhoose investigates unexplained loss from the supply entering a property.
- Detached houses and bungalows account for 49.2% of accommodation in the Census 2021 built-up area. Tell the team where the accessible meter and stop tap are positioned and whether any branch serves garden fittings.
- Acoustic checks and pressure testing can help examine the relevant sections. Explain where an extension, drive or shared entrance covers the expected route and who can open any separately controlled space.
- Alongside Rhoose's detached majority, semi-detached accommodation represents 28.9% and terraced accommodation 13.7%. The respective rounded counts are 865 and 410, compared with 1,470 detached homes.
- These figures describe houses and bungalows together within the Census categories.
How does ADI Leak Detection Rhoose find a water mains leak?
The engineer isolates and pressure tests the supply pipe, listens along its route with ground microphones and confirms the leak with tracer gas before marking it. Once the position is found, the engineer explains it on site before any repair is discussed.
The pipe is usually a metre down and the sound of it travels, so tracing it first helps you avoid unnecessary digging.
Pressure testing confirms and measures water loss from the mains pipe. The engineer first isolates the supply at the boundary stop tap, then tests the pipe before tracing the leak.
Acoustic ground microphones pick up the sound of water escaping beneath the surface. The engineer moves them along the pipe route in short steps.
Hydrogen tracer gas is introduced into the isolated mains pipe and detected at the surface above the escape. The engineer uses this method where ground noise or a slab affects the search.
The water mains leak position is marked on the ground and measured back to a fixed point, so whoever digs knows where to open up.
Which company provides Rhoose’s public water supply and sewerage?

What happens after a water mains leak is found?
Water mains leak repairs by ADI Leak Detection Rhoose are guaranteed. If the leak is on Dŵr Cymru Welsh Water's side of the boundary stop tap, the report identifies that so you can pass it to them.
Every leak detection visit ends with a written report by the engineer who attended, with photographs and video, formatted for trace and access and escape of water insurance claims.
- The leak position marked on site and explained before you decide anything
- Photographs and video in the written report

What do people ask about water mains leak detection?
Four questions come up before a water mains survey: how long it takes, who owns the pipe, whether the driveway gets dug up and how the leak is pinpointed underground.
How long does a water mains leak detection visit take?
It depends on the property and how much of the system has to be tested, so the advisor gives you an estimate when you book.
Who is responsible for a leaking water main in Rhoose?
Your side of the boundary stop tap is yours and the street side is Dŵr Cymru Welsh Water’s, and the report says which side the leak is on.
Does finding a water mains leak mean digging up the driveway?
Water mains leak detection traces the pipe from the surface with acoustics, tracer gas and a pressure test. Digging happens once, at the marked point, only if you want the repair done.
What is leak noise correlation?
Leak noise correlation is a way of estimating where a leak sits on a buried pipe. Two sensors are clamped to fittings at either end of the run, the leak noise reaches each one at a slightly different moment, and the time difference gives a distance along the pipe. ADI Leak Detection Rhoose finds water mains leaks with acoustic ground microphones, tracer gas and pressure testing.
