Why is My Boiler Leaking Water? 3 Things to Check

Even a small leak from your boiler can be a nuisance and one that points to more serious issues with the unit. When your boiler is leaking, it is best to reach out to the professionals to get help. However, if you want to take a look at the boiler and see if you can spot the problem yourself, there are a few things you can check.

Before you get started looking at why your boiler might be leaking, take steps to secure your safety. Turn off the water supply to the home, turn off the boiler, and approach cautiously.

1. Fittings and Seals

On the lines bringing water to and from your boiler, there are many fittings and seals. You’ll also find seals on valves, such as the pressure relief valve and the water supply valve. Any of these fittings or seals might be the source of the leak. You may be able to tell which by simply examining them to see if they are wet. Loose fittings and seals may be able to be tightened to stop the leak.

However, sometimes they are a sign of a more serious problem. For example, a leaking pressure valve might be an indication that the pressure is too high in your boiler . In this case, tightening the fitting is just hiding the problem. You should reach out to a professional to make sure that your leaking fittings or seals are not the sign of another problem and to ensure they are tightened or fixed correctly and without compromising the safety of the unit.

2. Corrosion

Corrosion can also cause leaks in boilers. However, it can be hard to know whether the corrosion caused the leak or resulted from the leak as water exposure will speed up the process of corrosion. Sometimes corrosion can eat away at the actual tank of the boiler, which can cause very serious leaks that are immediately apparent. Or, corrosion might develop in other areas of the boiler.

Corrosion typically cannot be fixed and you will likely need to replace boilers that have developed serious corrosion. This is another reason to get boiler leaks fixed quickly, to avoid this leak from damaging the whole unit beyond repair.

3. Other Things Near the Boiler

It is possible that the water isn’t coming from the boiler at all. If the source of water is not immediately apparent on the boiler, take a look around it to see if you can spot something else that could be leaking. If you still can’t figure it out, your HVAC technician can help you rule out your boiler and other appliances as the source of the leak.

Invest in Boiler Maintenance

Regular boiler maintenance can help you avoid leaks and ensure you get a full lifespan from your unit.
