Irrigation and sprinkler leak detection in Cardiff
Irrigation leak detection finds leaks in buried irrigation pipes using acoustic ground microphones, tracer gas and pressure testing.

What are the signs of an irrigation leak?
A zone losing pressure, a green stripe in dry weather or climbing water use can indicate a leak. ADI Leak Detection Cardiff tests each zone and marks the leak before anything is dug.
An irrigation leak is buried in the garden, so these signs are usually the first you know of it:
- A zone that has lost pressure or stopped reaching the far heads
- Boggy ground or a green stripe on a lawn that stays through dry weather
- The controller running normally while the water use keeps climbing
- A pump cycling on and off with nothing calling for water
- Damage after landscaping, fencing or tree work
A falling pool level needs a separate swimming pool leak detection investigation to test the pool shell and circulation pipework.
Where do irrigation leaks occur in Cardiff?
Irrigation leak detection in Cardiff traces a hidden escape from the system supplying your garden or premises.
- Identify the affected zone, any visible wet ground and whether water continues to escape when the controls are off. Acoustic listening and tracer gas can help locate a concealed leak where the system allows those tests.
- For a business in Cardiff Gate or St Mellons, explain who can isolate the irrigation supply and authorise access to the relevant outdoor area. Give the site entrance and the actual unit rather than a correspondence address.
- Cardiff’s coverage includes named localities from St Fagans and Llandaff in the west to Rumney and St Mellons in the east. A full property address lets the office arrange the investigation in the right place.
- The findings follow your pipe layout and symptoms, helping you focus repairs on the section that is losing water.
How does ADI Leak Detection Cardiff find an irrigation leak?
The engineer pressure tests each zone, traces the pipe route and listens for the leak with ground microphones, using tracer gas where the pipe runs under paving. Once the position is found, the engineer explains it on site before any repair is discussed.
An irrigation system is a lot of buried pipe with a lot of joints, and it leaks quietly into ground that is meant to be wet.
Pressure testing checks each irrigation solenoid zone separately after isolation, usually identifying the failing circuit.
The leaking irrigation pipe route is traced across the garden, narrowing the search to that line.
Ground microphones pick up the sound of water escaping from irrigation pipes through soil, gravel and turf.
Tracer gas locates irrigation leaks beneath paving, decking or dense planting where sound gives a less clear result.
The irrigation leak position is marked and measured back to a fixed feature, with photographs for the landscaper.
What happens after an irrigation leak is found?
Irrigation pipe repairs can be carried out by ADI Leak Detection Cardiff if you want the work done. Otherwise the marked position and report let a landscaper or irrigation installer open one hole instead of a trench.
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
How do you arrange irrigation leak detection in Cardiff?
Send the form with your postcode and a technical advisor will call you back, confirm the service and book the visit.
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 irrigation leak detection?
Irrigation owners ask how long the survey takes, whether the system can be tested switched off and whether the lawn gets dug up.
How long does an irrigation 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.
Can an irrigation leak be found with the system switched off?
Irrigation leak testing needs the zone pressurised for the leak to make a noise, so testing takes place live, one zone at a time.
Does irrigation leak detection mean digging up the lawn?
Irrigation leak detection traces the pipe from the surface and marks the leak without digging up the lawn. Only the repair opens the ground, at one spot.
