Boiler Leaking Water: How to Repair It

A boiler is a demanding appliance. It requires more attention and maintenance than most other home appliances. Older boilers are more vulnerable to myriad types of leaks. Although new boilers are more evolved, they too are susceptible to leaks. Here are some common causes of boiler leaking water that should help you to understand the problem.

Water Pressure Fluctuation

Regardless of the type of boiler you have, it will have a pressure outlet pipe. This is a relatively small pipe that is at the side of a boiler without any fittings. This pipe may drip at times. This is designed to reduce the pressure inside the boiler by letting some water flow out. If the drips are rare and if they are contained, you don’t need to worry. But if you find the dripping to be continuous and it is getting worrisome, then you need to step in. Do not block this pipe or cap it off. This will increase the pressure inside and you may have a problem more severe than a normal boiler leaking water.

If you don’t allow pressure regulation, the boiler could explore or it can collapse. Be worried when the pipe drips endlessly and allow a copious amount of water to flow out. This indicates the outlet pipe is overreacting or there is something else wrong with the boiler. In most cases, you simply have to reduce the pressure the tank is being exposed to. Reach out for the pressure gauge, which is at the side of the tank and regulate it.

Damaged Seals

There are boiler seals which may allow more water to flow out when the seals are not in optimal condition. You may want to replace the boiler seals if they are damaged or worn out. You must be sure that it is the seals causing the leak and not some other component. Get a plumber if it is a little perplexing.

Cracks in the Boiler Body

This is common in very old boilers. New boilers should be able to stay in proper condition for years before there are fatigues due to stress. The cycle of heating and cooling will always have a bearing on the metal. Expansion and contraction can cause splits, cracks or fissures and those may facilitate leaks. The problem may also be of loose joints. You may want to tighten loose joints or call your boiler supplier if you cannot figure out the exact reason.
