Confirmed with customer that water heater stopped producing hot water. Customer wanted to get heater replaced. Due too spacing had to install a 40 gallon so water heater would fit. Turned water and gas off to unit and drained water heater. Removed old water heater and installed earthquake straps on concrete wall. Installed new 40 gallon customer supplied water heater and filled tank. Turned gas back on and tested for leaks verifying no leaks on gas line to water heater. Set temperature to 120. Thank you for choosing CPI plumbing and heating.
