Leaking boilers should not be ignored. If left untreated, they can cause serious damage and pose a health risk. It is important to have your boiler inspected promptly by a Gas Safe engineer. This will help you save a lot of time and stress.
A boiler leak can be caused by poor installation, age-related deterioration, or excessive pressure. No matter what the cause of the leak, it is important to get it fixed as soon as possible. Here’s a guide to help you identify and fix a leak.
Why does my boiler leak water?
If a boiler is working properly, you shouldn’t see water leaking from it. But if it does, it could be due to:
- The system’s water pressure is either too high or too low.
- The heat exchanger, which transforms cold water into warm water, has been damaged.
- It is possible that the joints connecting piping and boiler were not properly sealed during installation.
- It is possible that your system is an older one and you need boiler servicing or repairs on certain parts.
A lot of times, a leak can often be repaired without the need to replace the boiler. However, this all depends on the severity and type of the leak.
Common causes for boilers leaking water
Leaking heat exchanger
This happens with older or budget boilers. It is not something you can diagnose by yourself. A professional engineer will come to your home to help you.
Leaking heat exchangers could spell doom for your boiler. However, there are times when it can be repaired. It is often more economical to purchase a new boiler than replace it.
High water pressure
Boilers can become irritable if they are subject to too much pressure. This causes them to fail. The boiler’s pressure gauge should be checked. Anything above the 1 mark or the green bar indicates a problem.
Bleeding the radiators is the best way to reduce high water pressure. Before you begin, make sure that the filling loop taps underneath the boiler are closed. To relieve the boiler’s pressure, use a radiator key to turn the radiators until the water escapes. Bleed the radiator at the highest point of your property, such as a bathroom towel rail. The air will rise through the system and end up there.
Leaking boiler pipes
A boiler leak can be caused by corrosion of the pipes below the boiler. It can also happen due to poor installation. However, this is less common. If the pipes are leaking or wet, this could be the cause of the problem.
To fix the leaking boiler pipes, a qualified gas engineer must be called. You can also help to contain the water by placing a bowl under the boiler to catch it and prevent it from running across the floor below.
Leaks in boilers’ internal parts
Some leaks are not as easy to spot. If your boiler is leaking and you cannot find the source externally, then it’s time to check within the internal systems. The result of sustained pressure and decay inside the system can lead to internal boiler leaks at joints and seals. Water can quickly escape from seals that are damaged.
If you feel comfortable, you can take off the boiler’s cover to inspect it. You can also call an engineer to quickly spot the problem. Seals are usually easy to repair and don’t cost much to replace.
How can you check for leaks due to poor installation
You may not be able to tell if the leak is caused by poor installation unless you are an engineer. Boiler pipes that leak can indicate that your boiler was not installed to the correct standard.
Only a Gas Safe engineer can fix this problem. A new boiler installation may be necessary to correct the problem. Although it may cost more than you expected, this will ensure your safety and that of your family.
Is this an emergency?
An experienced Gas Safe engineer should be contacted if you suspect or spot a leak in your boiler. The leak, no matter how small or large it appears, can cause extensive damage to your boiler and property.
Leaks are often easy to fix and most people can easily clean or drain a radiator. If the diagnosis of the cause of the leak is wrong, it could lead to more problems. If you have any questions, contact the company that installed your boiler system.
What should I do if my boiler leaks oil or gas?
Boilers should not leak oil or gas by design. You should always treat any oil dripping or suspected gas leaks as an emergency. Gas leaks can release carbon monoxide into your home. This gas is completely odourless and should be treated immediately. Landlords are required to have them installed in their rental properties. Carbon monoxide poisoning can lead to death.
You should immediately open all windows and extinguish any naked flames if you feel sick, tired, dizzy, or have a headache.
Leakage of oil can be detected by smelling it. You may also notice stains and pooling on surfaces nearby. To stop the oil from spreading, shut off the tank’s valve or tap, and open all windows. Furthermore, contact a local plumber to assist you if your boiler begins to leak oil or gas as they are experts in a variety of boiler services, including leak detection and repairs.
