Help and guidance on a leaky boiler
Firstly, you should never try and fix a leaky boiler yourself. Instead, shut off the boiler and call the experts. It is also illegal for anyone to use a gas appliance if they think that it might be dangerous!
A leaky boiler could be something serious and should be looked at by a Gas Safe Registered engineer as soon as possible.
Boiler leaks usually tend to mean that an internal component could be broken, such as a valve or seal. If left unattended, it could lead to rust and corrosion, or may even cause a short circuit within the electric components. Therefore, you need to contact your trusty engineers immediately when you spot the leak.
An expert engineer will look at the boiler and determine exactly where the leak is coming from – the bottom or from inside.
What could cause a boiler leak?
There’s a number of reasons why your boiler may start to leak. Here are just a few examples, all of which should all be fixed by a Gas Safe registered engineer.
If the leak is coming from the pressure valve, it might mean that the boiler pressure is too high. It should be between 18 and 21 PSI. When the pressure exceeds this, the relief valve will leak water to stop the appliance from blowing up.
It could also be leaking from the temperature valve. This means that the boiler temperature might be too high. It could be caused by a fault with the temperature probe.
The leak could be coming from the boiler pump seals. They may need replacing, or the pump could require resealing.
Badly fitted pipes could cause leaks from the boiler. Repairs to a badly fitted machine might be possible but sometimes a replacement may be required.
One of the main causes of a boiler leak is corrosion. Corroded tanks and pipes can lead to a weakened system and cause leaks to occur. If a valve has corroded it can be replaced. If the corrosion is more serious, a new boiler might be more economical in the long run.
