Customer called about issue with a leaking water heater. They called in early in the morning and were on the scheduled later on that afternoon . After our plumber Mario arrived to home , he was able to diagnose why the water heater was leaking. The company who installed in before did not add certain components needs to help the water heater. Mario was able to add these with parts he already carried on the truck. Customer was satisfied and more importantly no more leaking water heater.
