Over pressure?

Author: Cdffyrfytr (OR)

My hot water will drain water through the pressure relief at the top which I have going to a bucket. It will fill a five gallon bucket in two weeks and my shower which is on the other side of the hot water heater, inside the house constantly drips also. Do I have the hot water cranked up to high. This is the second hot water heater and the both did this. Could it be a back flow problem. Thanks for your thoughts.

Author: packy (MA) get a hose valve gauge and screw it on the drain for the water heater. open the drain and read the perssure. leave it on overnight and monitor the highest reading using the lazy hand on the gauge. could be an expansion issue which will require an expansion tank.

Author: Cdffyrfytr (OR) Thanks for the advice, the house was built in 1953 and our last addition the plumbers used Pex? pipe. I am needing to replace the rest of original plumbing. Should I stick with that or use something different. Is that where my expansion is possibly coming from?

Author: Paul48 (CT) If there is a PRV (pressure reducing valve)on the incoming line to the house, there should also be a potable water expansion tank between it and the water heater.It creates a closed system and doesn't allow for expansion. Just a thought.
