: Our County increased water pressure and our pressure relief valve on our 20 gal. electric water heater blew. The 60 gal. water heater did not blow. We have replaced the valve three times believing we had faulty valves, and it continues to leak even when the electricity is off. Any suggestions?

Don,
Yes, install a pressure reducer if the pressure is over 80 PSI.
Then install an expansion tank on the cold water side.
