– Your hot water heater operates at a high temperature and a high pressure.
– All water heaters are equipped with a TPR valve (temperature pressure release) which lets pressure escape if it gets too high.
– The TPR valve should have a discharge pipe attached to it that ends about 6 inches from the floor. It is very important to have this discharge pipe attached to the TPR valve. If there is no pipe attached, and you are standing near the valve when it lets off excess pressure, you will be badly scalded by steam and burning water.
– A properly functioning water heater will occasionally let off water through the TPR valve. If the pressure release valve is not functioning properly, it is possible for the water heater to become over-pressurized and actually explode.
Compare the diagram below with your water heater. If you do not see a discharge pipe, for your safety, you need to remedy the situation immediately. (Also if you see rust, corrosion, etc., it’s time to get your water heater inspected before a major failure and catastrophe occurs.)
