Hi,
I have a 40 Gallon Water Heater that runs on Natural Gas. Since Last night, the hot water throughout the house was only luke warm. I have now noticed that the overflow pipe was gushing with water running down the drain. I had to shut-off the inlet valve to stop it from overflowing. But as soon as I did that, there is NO water when I turn the hot water tabs on in the house.
Earlier this evening I tried flushing any sediments out by connecting a garden hose and draining the water in the heater. The water was clear and seemed to flow nicely. But everytime I turn of the inlet pipe through its valve (and as soon as I turn it on), the water seems to start gushing from the overflow into the drain. There is no leakage at the Pressure valve.
Any help is greatly appreciated.
Thanks.
