**ANNUAL WATER HEATER FLUSH** Tech Notes: Upon inspection for todays flush we found that this is rheem 50 gallon natural gas water heater located in the garage of home, and is 12 years of age which is outside of manufacture warranty. I made her aware that due to the water heater being outside of manufacture warrant, and the age of the unit that we would not be able to perform the flush for todays visit due to liability reasons. I found that the thermal expansion tank was full of water, and is no longer functions properly. While on site I checked whole home water pressure, and received a reading of 90-95 psi which is outside of state code regulations, and means the PRV has failed. I made h/o aware that these two things will cause secondary damages to the fixtures through out the home if not addressed. The h/o stated she would not be able to address these repairs today. Resolution: The PRV along with thermal expansion tank will need to be replaced to help fix/prevent any future plumbi
