Homeowners panic when they see water where it shouldn’t be, and you are likely no different. Even though you might be prepared to act when you notice some drips beneath your sink, it’s a different story when there is water underneath your boiler.
Whereas your water heater is the storage tank that heats water that runs through your plumbing, the boiler is used to help heat your home. Hot water, or sometimes steam, circulates through the home and provides heat through your radiators. The boiler can also heat the air used in a forced air system.
Because of this, it is far more likely that you would use your boiler more during the winter. However, there is no specific season for an unfortunate leak, and finding water under your boiler could happen.
To minimize the damage both to your boiler and your property, address this problem as soon as possible. One of the probable causes for the leak is corrosion. When either the tank, pipes or valves deteriorate, water will escape. Those parts will need to be either repaired or replaced, depending on the severity of the corrosion.
Ideally, your boiler should keep an even the amount of pressure, but that pressure could increase. An accumulation of calcite or limestone can force the pressure to rise toward dangerous levels, which then leads to leakage. To prevent the tank from rupturing, that water may leak from the valve and relieve some pressure.
Last, the cause could be from years ago. Either the boiler is old and past its prime, or the installation process was not adequate. Each of those circumstances will lead to leakage and may require a full replacement.
Addressing water under boiler issues should happen as soon as they’re noticed. Finding the source of the leak takes priority, and you can take steps to help stop and prevent more water from emerging. That leak may come from the discharge tube from the pressure release valve, the drain valve at the bottom of the tank, or from the tank itself.
You should then prevent further damage by disabling the water supply running to the boiler, and the power. Boilers are tricky systems for homeowners to deal with by themselves, so call a professional.
