Water Supply Pipe Replacement

Complete replacement of underground water supply pipes, from the property boundary to the building, across Southampton and Hampshire.

When a supply pipe is old, leaking in several places or made of lead, replacing it is often the best long-term solution. We replace underground water supply pipes from the property boundary all the way to the building, and we take care of both the external and the associated internal works.

What's included

  • Replacement of old or deteriorating supply pipes
  • New MDPE water supply installations
  • Replacement of leaking underground pipework
  • New points of entry into properties
  • Installation of internal stop valves
  • Connection to existing internal pipework
  • Flushing and testing on completion

Replacing a supply pipe isn't just about the pipe in the ground. The new pipe has to enter the building, be fitted with a stop valve and be connected to your existing plumbing. We handle the whole job, so you don't need to arrange a separate plumber for the internal connection.

Less digging with hydraulic moling

Where ground conditions allow, we can install the new pipe using hydraulic moling rather than digging a trench along its whole length. This can mean far less disruption to driveways, paths and lawns. Where trenching is needed, we reinstate the ground neatly.

FAQs

Supply pipe replacement questions

Will my water be off for long?

We plan the work to keep the time without water as short as possible. In most cases the new pipe is laid first, then the supply is switched over at the end.

What pipe do you use?

New supplies are installed in MDPE (medium-density polyethylene), the standard blue pipe used for underground drinking water supplies.

Do I need to tell my water supplier?

It depends on the work and on your supplier's requirements. We regularly coordinate private supply pipe works with water suppliers and can advise you on what's needed.
