Finding a boiler leak can really ruin your day, and somehow it always happens at the least convenient time. Although, let’s admit it, who is ever ready to face a leaking boiler without worrying about their budget and safety?
The good news is, a boiler leak will rarely pose a danger to your household but you still need to address the problem as soon as possible. In most cases a Gas Safe registered engineer will have to take a look, if a fault is suspected.
The first thing you can do to minimise damage is turn off the hot and cold water supply to the house. Do this the moment you notice the leak, and swiftly call an engineer.
What could have caused your boiler leak?
Problems with pressure
In this aspect boilers are very much like humans – they will cry (leak) and break down, if the pressure is too much. If you notice a puddle forming daily under your boiler it could be a sign the outlet pipe is working too hard, and water is dripping out. As tempting as it can be, don’t just patch the dripping pipe, as this can cause pressure to build up and lead to an explosion.
What you can do in this case is check if the filling loop tap under your boiler is firmly closed. This will be a silver flexi pipe with one or two black taps – check that they’re firmly closed and tighten them up if not. Next you can bleed your radiator system – trust us, it is not that hard.

Boiler seals damage.
The boiler seals are essentially the parts that keep your boiler together. They expand as the heat rises to withstand pressure. If a seal is damaged, it is not an expensive part to replace but it is also possible that the problem includes the boiler pump, which could add up a more significant charge.
Ultimately if your boiler is not nearing the end of its life a replacement will be beneficial but it’s always best to speak to a qualified engineer.
Corrosion could be the culprit
If you notice the boiler leak is coming from the pipes underneath, corrosion is a likely culprit. When water is combined with metallic parts from the system it will naturally corrode copper piping, and cause water to escape. If the corrosion is extensive and occurred over years and years, this is a big sign it might be time to say goodbye to your boiler, and start thinking of a new one.
If the boiler is less than seven years old it is worth discussing with an engineer, whether it can be saved – you’ll need to think of the cost of the current repair plus any future repairs, and compare it to the price of a new boiler. Our expert engineers can help.
Your boiler expands with the hot water and occasionally it’s possible for the joints to become lose. This problem can be solved with a simple tightening of the joints. However, if the issue persists the next day, there might be a more serious underlying issue.
Wear and tear
Sometimes we just have to admit a boiler is prone to wear and tear like any other appliance, and its life will eventually come to an end. As the time passes the metal shell will become damaged from the daily usage and start cracking and leaking water. This is a sign a new boiler should be on the way.
