This is the 3rd most common leak in a house. Surprisingly it is common to find a few leaks on a newly installed appliance. This does not always mean you have had a botched job, so don’t panic straight away.
Most boilers come with a 10 year lifespan. If your boiler is around this age and starts to leak, it could telling you it’s starting to corrode. Once this happens, damage is likely and once you start changing parts, new efficient parts can put more pressure old and tired areas of the boiler, thus perpetuating the cycle of repairs.
Our advice is by-all-means fix the problems but when you have several repairs in a relatively short space of time and the boiler is more than 10 years old, it may be more cost effective to install a new one.
Here are a few main parts that can either leak or create leaks and why:
If your boiler pressure is too high, this may create a leak as the excess pressure needs to purge and release water to stop it from imploding. You can lower the boiler pressure yourself and it only takes up to 10-20 minutes. The best way to do this is by, bleeding a radiator or a drain valve
Wear and tear of the pipe connections can result in joints becoming loose from expanding and contracting overtime. This isn’t a big deal in terms of repairs but the joints will need to be sealed as soon as possible to protect other areas of the boiler from corrosion.
Finally, a leaking boiler could quite simply be caused by poor installation; this is often the case when water is coming from a pipe fitting.
It can be hard to spot potential leaks when installing and can take a few hours to show. If you notice moisture on the pipes or below the boiler, call the engineer back to rectify the job.
If your engineer is being evasive, you should be able to report him/her to the GasSafe Register and they will be able to help.
There are many more reason why a boiler can leak. If you do discover a leak for any reason, please follow these steps below until help arrives.
1. Turn off the water supply
2. Switch off the heating
3. Wipe up any water and use a container collect drips or streams
4. Contact a qualified engineer – don’t wait!
