If you spot water accumulating anywhere near the water boiler, you should be concerned. Any sign of water leakage from a boiler is an indication of a serious issue. Here are five reasons a boiler may be leaking and how to stop it.
A water boiler has a valve that helps to keep the temperature and pressure inside the boiler within a safe range. If the valve is leaking water, this means the temperature or pressure is exceeding safety standards. This could be because of sediment in the system, or because the valve has failed. Open the valve for one to two seconds to allow it to release the sediment trapped in the boiler. If doing that doesn’t stop the leaking, the valve needs to be replaced.
If you spot water around the boiler and there are rust stains on the side, that is usually an indication of corroded connections between the water pipe and the inlet and/or outlet connections of the boiler. Check the connections for corrosion or signs of rust and, if they are present, make an appointment for a plumber in Harrow from Plumbers 4 U to replace them.
Replace Drain Valve
Water leaks from a boiler could indicate the washer in the drain valve has corroded and no longer forms a tight seal, or that there is sediment stuck in the valve that doesn’t allow it to close all the way. This problem usually appears after cleaning sediment from the tank. You can try to stop the leak by running water through the system again to clean more of it out. However, a plumber will probably have to replace the washer or valve to correct the problem.
Check the Threads
Anywhere there is a threaded connection on a water boiler, there is a potential for a leak. This could be because the gasket used to seal the connection is bad or there is corrosion. Stopping leaks involving these connections may just be a matter of replacing the gasket and using plumbers tape to stop leaks when reconnecting the ends. This could be around the anode rod at the top of the boiler, the hot water elements, or the thermostat.
If you spot water on the floor under the boiler, you should inspect the tank for leaks. If the insulation is damp around the burner, water is leaking from the seams of the boiler, or there is water present around the heating element door, then the tank is leaking and needs to be replaced.
