This page is here to help homeowners in Walton on Thames who may be experiencing a mains water leak, including high water bills, water meter movement, leaking supply pipes, and leaks between the water meter and property.

Unexpectedly high water bills, a constantly moving water meter or a notification from your water supplier can sometimes indicate a mains water leak affecting buried supply pipework between the meter and property. Walton on Thames (KT12) includes a mix of detached homes, period properties, riverside developments, family housing and modern residential neighbourhoods where water supply pipes often run underground between the property boundary and the home.
The mains water supply pipe is responsible for carrying water from the water company’s network into the property. In Walton on Thames, these pipes commonly run beneath driveways, gardens, pathways and outside areas before entering the building. When a fault develops within the supply pipe, water can escape continuously underground without obvious signs appearing immediately at the surface.
Our mains water leak detection Walton on Thames service uses acoustic listening technology, tracer gas testing and specialist leak location equipment to trace leaks within buried supply pipework. These non-destructive methods allow us to identify the exact leak position accurately while helping minimise unnecessary excavation and disruption. We carry out mains water leak investigations throughout Walton on Thames and nearby areas including Hersham, Molesey and Weybridge, while our wider service operates across the county through our Mains Water Leak Detection Surrey service.

Mains water leaks can be difficult to locate because the affected pipe is usually buried underground between the water meter and the property. Many homeowners first become aware of a problem after receiving an unusually high water bill, noticing water meter movement when no water is being used, or being contacted by their water supplier.
The Leak Hunter specialises in locating leaks on incoming mains water supply pipes. Using non-invasive leak detection techniques, we accurately trace the source before excavation or repair work begins, helping to minimise disruption and avoid unnecessary guesswork.
Once the leak has been confirmed, we can advise on the most appropriate solution and carry out any required repairs.
Common Signs of a Mains Water Leak
Many homeowners in Walton on Thames contact us after noticing a sudden increase in their water bills, unexplained water loss, or unusual activity on their water meter. Because mains water supply pipes are buried underground, leaks can often develop without obvious visible signs.
You may benefit from mains water leak detection if:
Your water meter continues to move when all taps and appliances are turned off.
Your water bill has increased unexpectedly.
Your water supplier has notified you of unusually high consumption.
You have noticed wet ground, standing water, or soft areas in the garden.
Water is appearing around driveways, paths, or external hardstanding.
You have experienced a reduction in water pressure.
You suspect a leak on the pipe between the water meter and your property.
If any of these symptoms sound familiar, specialist testing can confirm whether the problem originates from the incoming mains water supply pipe and identify the location of the leak before excavation begins.
Not sure what’s causing the issue? Our engineers can review the symptoms and advise on the best next step.
Every mains water leak investigation in Walton on Thames begins with confirming that the problem is affecting the incoming supply pipe rather than internal plumbing within the property. Once this has been established, we use specialist leak detection equipment to narrow down the location of the leak before any excavation is considered.
The exact methods used depend on the pipe material, installation depth, ground conditions, and the symptoms present. Investigations may involve acoustic leak detection, tracer gas testing, pipe tracing, pressure testing, and other non-invasive techniques designed to locate mains water leaks accurately.
Our objective is to identify the source with as little disruption as possible. By confirming the location before repair work begins, unnecessary excavation can often be avoided and access can be limited to the affected area only.
Mains Water Leak Repairs
Once the leak has been located in Walton on Thames, we can advise on the most appropriate repair based on the condition of the pipework, the location of the leak, and the surrounding ground conditions. Every repair is planned around the confirmed leak location, helping to minimise unnecessary excavation and disruption.
Where possible, access is limited to the affected area only. This may involve exposing a small section of the supply pipe for repair, replacing a damaged section, or carrying out more extensive work where the condition of the pipe makes replacement the better long-term solution.
Following repair, the pipework can be tested to confirm the leak has been resolved before reinstatement takes place. Our aim is not only to find the leak, but to provide a complete solution that restores the integrity of the water supply and gives homeowners confidence that the problem has been properly resolved.

Mains Water Leak Detection FAQs
How do I know if I have a mains water leak?
Common signs include unexpectedly high water bills, water meter movement when no water is being used, wet ground, reduced water pressure, or being contacted by your water supplier about unusual water consumption. Specialist testing can confirm whether the leak is affecting the incoming supply pipe.
Can you find a leak without digging?
In many cases, yes. We use non-invasive leak detection techniques to locate mains water leaks before excavation is considered. The aim is to identify the affected area accurately and minimise unnecessary disruption.
Do you repair mains water leaks once they have been found?
Yes. Once the leak location has been confirmed, we can advise on the most appropriate repair and carry out the work required to restore the integrity of the supply pipe.
Will my driveway or garden need to be excavated?
Not necessarily. Every effort is made to locate the leak accurately before excavation begins. If access is required, it is normally limited to the area surrounding the confirmed leak location.
Am I responsible for repairing a leaking supply pipe?
In most cases, homeowners are responsible for the section of pipe running between the external water meter and the property. We can help confirm the leak location and advise on the most appropriate next steps.
Can you provide documentation for insurance claims?
If requested, we can provide a detailed trace and access report suitable for insurers, confirming the leak location, the testing carried out, and any repairs undertaken.
