Water Heater Leaking From Boiler Drain

A leak in the drain valve at the bottom of the water heater is another common issue.

Water heater leaking from boiler drain.

After draining or flushing a water heater it is common for the drain valve to fail to close completely. While you can repair similar valves such as garden spigots it s not a good idea to attempt a repair on a water heater drain valve. First you ll need to stop the flow of new water into the tank and drain it so you can work. Another reason your hot water heater may be leaking from bottom could be due to an internal leak.

And water to leak slowly from the water heater overflow pipe gushing pipes and overflow at the bottom of the tank. To turn the water feed off on a toilet cistern use the isolation valve. A leaking water heater drain valve is not always a complicated problem. It water appears to be leaking from the valve try tightening it with a wrench until it is snug but be careful not to over tighten it.

Sometimes the valve gets bumped and becomes loose or the moisture is caused by something other than the drain valve. Or may be leak in the drain pipes of the hot water system overflow pipe water heater running. Flush the toilet to drain the water. Overtime if the tank is not regularly flushed out this build up can cause the tank to rust and spring a leak.

If the repair isn t successful you ll have water. Like all water valves the drain valve on your water heater can wear out and leak often this happens after you drain the water heater as part of the regular maintenance of the unit but it can happen anytime. Water heater drain valves are used to drain the hot water from the tanks which is a common maintenance task done to remove built up sediment. One of the most common causes of water heater leakage is a loose drain valve.

Turn off the water to the coil and check if the pressure stops rising. This is a valve located on the water pipe that leads into the cistern. In most cases a build up of sediment is the leading cause of this. This drain valve can be capped with a hose cap or you can replace the drain valve completely with a new valve.

Sometimes this coil will develop a pin in it and this causes pressure to seep into the boiler and leads to leaks in the pressure relief valve. It s always a good idea to confirm the source of the water before assuming it s the drain valve though. Some boilers have a tankless water heater or what is also known as a hot water coil. Leaking may be cause by the old pipes or by the water heater overflow pipe of hot water heater pipe leaking.
