I returned to install a new tankless water heater. The process began with the removal and disposal of the existing water heaters. I then retrofitted the gas and water lines to fit the new tankless unit. The water line for the sprinkler system was relocated and secured next to the wall. I installed a 2” exhaust pipe leading outside and connected the condensation line to a nearby sink. After ensuring all connections were secure, I checked for leaks and confirmed there were none. Additionally, I verified the absence of water and gas leaks. The new tankless water heater comes with a 2-year labor warranty and a 15-year heat exchanger warranty from the manufacturer.
