Water Mains & Supply Pipes in Portsmouth
A leaking supply pipe wastes water you are billed for and can undermine what sits above it. Moling lets us put in a new run without digging up the whole garden.
What you are actually dealing with
The pipe running from the boundary stopcock to your property is your responsibility, and on older properties around Portsmouth it is often lead, old iron or early plastic that has reached the end of its life. The first sign is usually pressure dropping off, a damp patch that never dries, or a water bill that has quietly doubled.
We trace the line, confirm the leak location and give you the choice between a spot repair and a full replacement. Where the run is long or the existing pipe is lead, replacement is almost always the better value answer.
Most replacements are done by moling — a pneumatic head driven underground between two small pits, pulling the new pipe behind it. Two holes instead of a trench, finished in a day, lawn and driveway intact.
What the job covers
- Supply pipe leak detection
- Lead pipe replacement
- Mole-driven pipe renewal
- Boundary stopcock and meter work

- New supply installation
- Pipe location and depth tracing
- Pressure testing and sign-off
Method
How we handle water mains
Trace
The existing run is located and the leak pinpointed using acoustic correlation before a single spade goes in the ground.
Options
Repair versus renewal priced clearly, with the likely lifespan of each set out so the cheap option is an informed choice.
Install
New MDPE pipe moled into position between entry and exit pits, connected at both ends and pressure tested.
Finish
Pits backfilled and reinstated, supply proven, old pipe capped off and decommissioned.
Questions
Water Mains — the usual questions
Straight answers, including the ones that mean we do not get the job.
A simple meter test with the internal stopcock closed will normally tell us. If the leak turns out to be the water company's, we will tell you and you should not be paying us to fix it.

Blockages rarely clear themselves and broken pipes never do. A phone call costs nothing and usually tells you whether this is urgent.
