Customer had water coming from relief line on water heater. We had installed water heater 9/29/23. I replaced the pressure regulator valve due to water pressure was reading over 80psi. I replaced the original gate valve with a 1/4 turn ball valve. The T&p valve was replaced and reconnected to the relief line. The expansion valve was removed from the system and capped off. Pressurized system and aired out. Checked and verified system was functioning properly. Thermal expansion tank air bladder was still intact. Water pressure is set to 65psi.
