Water mains leak detection in Fence Houses
Water mains leak detection finds hidden leaks in underground supply pipes using acoustic ground microphones, tracer gas and pressure testing.

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 Fence Houses 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 Northumbrian 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 Northumbrian 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 Fence Houses?
Water mains leak detection in Fence Houses starts with the supply to the affected building.
- The settlement crosses the Tyne and Wear and County Durham boundary, with part of Fencehouses in Little Lumley parish.
- The team needs the property location and the water-loss symptoms together, rather than the council name alone.
- Describe the outside route where it is known, the position of the stop tap and any wet ground beside the building.
- Woodstone Village and High Dubmire both have DH4 addresses, so identify the locality as well as the postal district.
How does ADI Leak Detection Fence Houses 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 handles water and sewerage for Fence Houses?
Northumbrian Water is identified for water supply and sewerage at Fence Houses. The settlement’s council boundary does not by itself establish who is responsible for a particular pipe. Check the affected connection with the provider, and describe whether the reported escape concerns the supply into the property or drainage leaving it.
Who maintains the private water supply pipe?
The homeowner or landlord maintains the water pipes on the property, including underground pipes in the garden or driveway and pipes inside the building. This can include pipework laid in another owner's private ground.
Who maintains a shared water supply pipe?
Where several properties share the private supply pipe, the owners share responsibility for maintaining and repairing it.
What happens after a water mains leak is found?
Water mains leak repairs by ADI Leak Detection Fence Houses are guaranteed. If the leak is on Northumbrian 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

If you are unsure which investigation you need, describe what you can see when you call and the advisor will tell you.
Same or next day depending upon engineer availability.
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 Fence Houses?
Your side of the boundary stop tap is yours and the street side is Northumbrian 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 Fence Houses finds water mains leaks with acoustic ground microphones, tracer gas and pressure testing.
