Water was flowing from the overflow pipe of my electric water heater. I turned off the valve where the water flows into the tank. That stopped the flow, of course. Is there anything I can do to fix the problem and turn the water back on? Also, if I leave the heater the way it is until a repairman comes will anything be damaged?
Electric water heater– turn off the electric breaker to the heater. You will burn up your heating elements. The overflow is called the T&P relief valve. That has popped. Push the flip lever back down and see if it blows again. If it does turn down the temp. If that does not fix it purchase a new one.
If the pipe coming out of the T&P is pvc-cut it in half, and also purchase a coupler of the same size(should be 3/4″). Unscrew the pipe from the old T&P. Unscrew the bad T&P–caution water may come out but only to that level. Screw the new t&p into the same place. Screw in the pipe you removed from the old t&p and then use the couple to attach the drain back together.
If PVC-use pvc glue If copper-you will have to sweat the drain back together.
