Are you considering a Lead Water Pipe Replacement?

London Lead Water Pipe Replacement Experts.

In certain scenarios, replacing the water paper completely is a more effective solution than carrying out water leak repairs. Old pipes can become problematic as they corrode with age and risk further leaks occurring. Damaged or corroded pipes can lead to hidden leaks that reduce the water pressure to your home, causing problems with your washing machine, power shower, dishwasher and central heating system.

By replacing the supply pipes completely, the possibility of further leaks is reduced and can become more cost effective than continuing to repair old pipes. During the process, we use a thrust bore mole to install the pipe which causes less disruption to the surface, resulting in less land scarring. As well as issues with corrosion, older pipes can also fail to provide adequate flow for modern demands due to their narrow design so may benefit from an upgrade.

If you are considering lead water pipe replacement, we offer a free of charge survey. One of Our water engineers will attend your property to assess the site and provide you with a fixed price quotation for increasing the size of the pipe at your property or carrying out lead water pipe replacement for corroded pipework

considering a Lead Water Pipe Replacement

If you require a new water main from the meter to the house, look no further than the mains water supply replacement experts Brennan Moling. Many older homes were originally piped with either galvanised, copper or lead materials, and over time may have developed leaks along the way, particularly common in the water main pipe to the house.

These pipes when leaking or burst may often go unnoticed until you get a large water bill as they are generally under ground and not noticable. Low water pressure, rusty coloured water, and leaking pipes are just a few of the symptoms of poor quality piping. All will lead to pipework replacements.
