I had a rental hot water tank from Reliance that started to leak slightly, even though it was only 5 yrs old. When a technician came to inspect the problem, it was also noticed that, due to a previous installation of a direct vent furnace, the combustion in the water tank was not efficient, and was leaking gasses into the basement. It was recommended by Robert to have a PowerVent hot water tank installed to eliminate the problems. Robert and Steve did the installation in a minimal time, and were amazingly professional. They ensured that all items in my house were protected while they worked, and they explained everything as they worked. Kudos to both of them for an excellent job well done.
