What does leak detection in Rhyl include?
An ADI Leak Detection Rhyl engineer traces the leak from the surface and marks it before anything is dug up. You get a written report for your insurer, and we repair plumbing, heating, water mains and swimming pool leaks.
- Non-invasive methods: The leak is traced from the surface, so walls, floors, tiles and driveways are opened only at the marked point, and only if you want the leak repaired.
- Acoustic listening: Ground microphones pick up the sound of water escaping beneath the surface.
- Thermal imaging: The camera reads the heat pattern of a hot water leak through plaster and screed.
- Tracer gas: Hydrogen tracer gas is introduced into the isolated pipe and detected at the surface above the escape, through screed, timber, tile or ground.
- Moisture meters: Pin and pinless meters measure the spread of damp around a leak, separating a live leak from an old stain.
- Trace and access report: Every investigation ends with a written report by the engineer who attended, with photographs and video, written for trace and access and escape of water claims.
- Find and fix: Plumbing, heating, water mains and swimming pool leak repairs are guaranteed; roof and structural causes are located and reported in full.
- WaterSafe approved: ADI Leak Detection is a WaterSafe approved contractor.

Which leak detection service does your leak need?
If you are unsure which one you need, describe your leak when you call and the advisor will tell you.
Water mains leak detection traces the supply pipe from the boundary stop tap to the house through tarmac, block paving, soil and concrete.
- Methods
- Acoustic ground microphones, tracer gas, pressure testing
Central heating leak detection traces pressure loss through heating pipework hidden under floors, screed or plaster.
- Methods
- Tracer gas, thermal imaging, pressure testing
Acoustic listening and thermal imaging locate plumbing leaks inside walls, under floors and above ceilings before opening up.
- Methods
- Acoustic listening, thermal imaging, tracer gas, borescope
Bathroom leak detection tests shower trays, wet room formers, sealed joints and the pipework behind them.
- Methods
- Thermal imaging, moisture meters, borescope
Ceiling leak detection traces a ceiling stain back to the leaking roof, bathroom or pipe.
- Methods
- Thermal imaging, moisture meters, acoustic listening
Swimming pool leak detection tests the liner, filtration pipework, pumps and pool structure one system at a time.
- Methods
- Tracer gas, pressure testing, dye testing, underwater inspection
Roof leak detection checks slate, tile, flashing, gutters and flat roof membranes from the ground, roof and air.
- Methods
- Thermal imaging, moisture meters, drone inspection
A drain camera inspects foul and surface water drains from the chamber out.
- Methods
- CCTV drain survey, acoustic listening
Irrigation leak detection tests sprinkler and garden irrigation networks zone by zone without trenching the lawn.
- Methods
- Acoustic ground microphones, tracer gas, pressure testing
Is leak detection covered by insurance in Rhyl?
Most buildings policies include trace and access cover, which pays for finding the source of an escape of water and for the damage caused getting to it. Check your policy for the trace and access limit, because limits vary.
The engineer who found the leak writes your report, with photographs and video for your insurer. The claim itself is yours to make: we do not handle it, and a leak on the street side of the boundary may need a call to Dŵr Cymru Welsh Water instead.

Where does ADI Leak Detection Rhyl work?
Rhyl’s documented Victorian townscape and slate roofs help frame enquiries about older buildings. The team investigates water loss by following the symptoms within the property’s current layout. Explain which rooms are damp, what lies above them and whether water use changes the problem.
High Street, Sussex Street and Wellington Road also form part of the recorded commercial core, where an enquiry should identify the particular unit and entrance needed for access. Rhyl’s conservation account records nineteenth-century expansion followed by the conversion of boarding houses into flats.
Victorian and Edwardian buildings appear alongside brick, render, grey rubble stone and older stone terraces, giving the town a broader range of historic fabric than the slate roof covering alone.

How do you book a Rhyl leak survey?
Call 01745 296013, Monday to Friday, 7:30am to 6:30pm, or send the form and a technical advisor will call you back.
Rhyl enquiries can use the town council’s neighbourhood names, from Bodfor and Foryd to Trellewelyn and Tynewydd. Add the affected part of your property and whether the problem concerns a water supply, heating circuit, roof or drain. Those details help the office discuss an appropriate investigation.
If water is actively running, isolate the stop tap. Take a meter reading now and another in an hour: the rate of loss helps the advisor pick the right survey first time.
Same or next day depending upon engineer availability.

What happens when you call ADI Leak Detection about a leak?
ADI Leak Detection Rhyl discusses properties in the town’s named wards, including Bodfor, Derwen and Tynewydd. Give the precise location within Rhyl and the access needed to inspect the reported water loss.
Why does my boiler keep losing pressure?
Your boiler keeps losing pressure because water is escaping from the sealed heating system. The water leaves through a leak on the heating pipework or a radiator, often out of sight under a floor, or through a boiler fault, such as a failed expansion vessel that makes the pressure relief valve discharge water outside. If a heating engineer has ruled out the boiler, central heating leak detection finds the hidden leak with tracer gas, thermal imaging and zone by zone pressure testing.
Does ADI Leak Detection fix the leak as well as find it?
Yes. Leak repairs cover plumbing, central heating, water mains and swimming pools, with every repair guaranteed. ADI Leak Detection Rhyl locates and reports roof and structural leaks for a roofer and does not carry out roofing work.
Should I call ADI Leak Detection Rhyl or Dŵr Cymru Welsh Water?
Leaks on public land, and on Dŵr Cymru Welsh Water’s side of the boundary stop tap, are Dŵr Cymru Welsh Water’s to fix and should be reported to them. Leaks inside the property, and on your own supply pipe between the boundary and the house, are the property owner’s responsibility, and that is the work we do. Report a leak to Dŵr Cymru Welsh Water on 0800 052 0130, 24hrs a day, 7 days a week, or online at dwrcymru.com.
