Call out to complete sold work for replacement of a water heater. Begin work by shutting off water to the home and draining the system. One system was drained, removed old water heater and replaced with a new 6year tank water heater with a four year anode extension kit totaling 10 years of warranty. Also replaced all singlewall venting with new double wall venting. In order to meet code requirements, ran a new T & P line outside. Once all work was complete re-introduced water to the system and check for leaks and functionality. No leaks and everything is functioning properly.
