Arrived to customers home for a service call regarding a pipe leak on top of a water heater. After finding leak and giving customer options to fix the leak I started to take apart female connection on cold side of water heater where leak was. After taking everything apart I noticed that the threading was completely busted on unit itself. Went through options with customer on replacing the water heater and customer agreed. Got a Bradford white 40 gallon water heater and rebook system up. After installation there were no leaks or gas leaks when hooked up. Customer was very satisfied with services today.
