Customer had us out to replace their old water heater. We got there and drained the tank and removed it. We then installed the new water heater along with new water supply lines, new gas supply, a sediment trap, new t&p valve, new pan, and a new emergency water shutoff valve. We then turned the water on and inspect for leaks, which none were found. We turned the gas on and lit the water heater with no issues and set the temperature to the manufacture recommendation. I shed the customer everything we did and how to change the temperature if it is needed. Everything is working properly at this time. I found no further issues at this time.
