Isolate before you locate
A property can have several buried water lines, and knowing which one is leaking removes most of the search.
Work through them with valves. Shut off the irrigation supply and watch the meter. Then the feed to the garage or outbuilding. Then the house itself.
Each one you close either stops the meter or does not, and that answers which run has the problem without touching a spade.
Irrigation is worth checking first, because those lines are buried shallow, get damaged easily, and produce exactly the symptoms people assume mean a failing main supply.
Read the ground
Buried leaks leave surface evidence, and it is worth looking before paying for equipment.
A patch of grass that is greener or growing faster than everything around it is being watered from below. In dry weather the contrast is unmistakable.
Ground that stays soft when the rest has dried out.
Water surfacing on a path or driveway, often some distance from the actual break, because water follows the easiest route through the soil before it emerges.
That last point matters: the wet patch marks where the water got out, not necessarily where it left the pipe. It narrows the area rather than marking the spot, which is why tracing and acoustic location still earn their keep.
Does this sound familiar?
Problems this service solves
- A wet patch of ground with no visible source
- A buried line to a garage or outbuilding leaking
- An irrigation supply line that has failed
- A line damaged by root growth or ground movement
- A run damaged during landscaping or excavation
Signs you need underground water line repair
If more than one of these is true, the problem is usually past the point a plunger or a store-bought cleaner will fix.
- Ground stays soft or wet in one area
- Grass grows faster in a distinct strip or patch
- Water pressure has dropped at an outbuilding
- The meter moves when nothing indoors is running
What to expect
How the visit works
Isolate to narrow the search
Shutting off branches one at a time, an irrigation zone, an outbuilding feed, tells you which line is leaking before anything is dug.
Trace the route
Line tracing establishes where the pipe actually runs and how deep, which is rarely where it is assumed to be.
Locate utilities and dig once
Gas, electricity and communications are marked, then one targeted excavation is made at the located point.
Repair, test and reinstate
The failed section is replaced, pressure tested before backfilling, and the ground restored.
What's included
What you get on every job, whoever we send.
- Branches isolated to identify the line first
- Route traced rather than assumed
- Utilities marked before any ground is opened
- Tested before the hole is filled in
Questions
Underground Water Line Repair questions
How can a leak be found under a lawn?
By narrowing it before digging. Isolating branches one at a time, the irrigation, the feed to an outbuilding, the house, shows which run is losing water. Line tracing then establishes where that pipe actually runs and at what depth. Acoustic equipment picks up the sound of pressurised water escaping, which travels well through soil. Between them the position is usually narrowed to a small area, which turns a trench into a single hole.
Why is one patch of grass greener than the rest?
Because it is being watered continuously from below. A leaking buried line puts a steady supply of water into the soil around it, and grass responds. It is one of the more reliable outdoor leak indicators, particularly in dry weather when the contrast is obvious. The leak is usually near that patch but not always directly beneath it, since water follows the easiest path through the soil before it surfaces.
Should the irrigation system be checked too?
Yes, and it is often the answer. Irrigation lines are buried shallow, they are frequently damaged by digging and root growth, and a leak on one produces exactly the symptoms people attribute to their main supply: wet ground, a rising bill, a moving meter. Isolating the irrigation supply and watching the meter is a quick way to include or exclude it before anything else is investigated.
