Water main repairs and installation are essential when an underground supply pipe leaks, bursts, becomes restricted, or needs upgrading for a new property or development.

Many people use the term “water main” to describe the underground pipe that supplies clean water to a property. In practice, responsibility depends on where the pipe sits. Public water mains are normally managed by the water company, while private supply pipes on private land are usually the responsibility of the property owner.
Drains24 can help with private-side water pipe repairs, replacement and installation. This includes leaking supply pipes, burst underground water pipes, damaged pipework, poor-flow pipework, and new private water main installation for homes, developments and commercial sites.
We can also advise when a problem may need to be referred to the local water supplier, especially where the issue appears to sit outside the private boundary.

Drains24 can support new water main installation for new housing projects, property developments, self-build homes, extensions, conversions and private sites that require new underground water supply pipework.
A new water main installation may be needed when:
For new housing projects, correct planning matters. The pipe route, trench depth, access, connection point, ground conditions and future maintenance access all need to be considered before installation begins.
Drains24 can help with private-side installation work and coordinate practical preparation where a water authority connection or approval is required.
Older underground water mains can cause repeated issues. Some old pipes restrict flow, leak underground, affect water quality or become unreliable as they deteriorate.
Drains24 can help remove, disconnect or replace old private water supply pipework where it is no longer suitable. In many cases, replacing the old pipe provides a better long-term result than carrying out repeated small repairs.
Old water main replacement may be recommended when pipework is:

Older properties can still have ageing underground water mains made from materials that are now considered outdated or unreliable. These pipe types often cause low pressure, leaks, poor flow or concerns over water quality.
Lead pipes were commonly used in homes built before 1970. They can pose a health risk, especially where drinking water passes through the pipe before reaching taps inside the property.
Lead pipework can also become soft over time. Underground pressure, ground movement and age can squash or deform the internal bore, restricting water flow and reducing pressure.
Unpainted lead is usually dull grey and feels soft compared with copper or steel. If lead pipework is suspected, it should be inspected professionally and replaced where appropriate.

Galvanised iron and steel water mains were common before the 1950s. These pipes can corrode internally as they age.
As corrosion builds up inside the pipe, the available bore becomes smaller. This works much like cholesterol narrowing an artery: the pipe may still be present, but the flow through it becomes severely restricted.
Common signs include poor water pressure, rusty water, slow flow and repeated pipe failures.

Black alkathene was an early plastic pipe material introduced during the 1950s and 1960s. Although it was once widely used, many early black alkathene mains are now reaching the end of their useful lifespan.
As the material breaks down, it can become brittle, unreliable or contaminated internally. Some failing black alkathene pipes may release black particles or cause discolouration in the water.
Where this type of pipe is failing, replacement is often the most sensible long-term option.

If you have a blocked drain, slow drainage or overflowing outside drain, Drains24 is ready to help.
We provide fast, reliable drain unblocking services with a focus on long-term results.
A damaged or ageing underground water pipe can cause problems before a major burst appears. Early signs should not be ignored, especially if the pipe supplies your home, business or development site.
Common signs include:
If you notice any of these signs, it is better to investigate early. A leaking or failing underground pipe can waste water, damage surfaces and create more expensive repair work if left unresolved.

Drains24 can help with a range of private underground water pipe issues. The exact solution depends on the pipe material, condition, location, access, depth and whether the pipe needs repairing, replacing or newly installed.
Our service can include:
We always aim to recommend the most sensible option. Sometimes a localised repair is enough. However, where old pipework is failing, replacement may offer better long-term value.

A burst underground water pipe can cause disruption quickly. Water may damage driveways, gardens, foundations, commercial yards or shared access areas. It can also interrupt the water supply to the property.
Drains24 provides fast support for urgent water pipe problems. If you suspect a burst, turn off the internal stop tap if safe to do so, avoid digging near unknown underground services, and call for help.
We can assess the issue, advise on the next step and attend where private-side repair work is needed.

Drains24 supports domestic, commercial and development projects. Underground water pipe problems can affect houses, rental properties, shops, hospitality premises, offices, workshops, industrial units, managed sites and new housing projects.
For homeowners, we focus on clear advice and practical repairs. For landlords and property managers, we help reduce disruption and keep tenants informed. For developers and contractors, we can assist with private water main installation, old pipe removal and new supply pipe routes.
