Project includes replacing 50 gallon gas water heater. Will need 1/2 copper pipe also will need 3inch flue and adapt to gas line. PT-12/2/22. Removed the old 50 gallon hot water heater and installed a new Bradford white 50 gal hot water heater. Model #rg250t6n, serial #yk50410151. All copper connections were made using 1/2 pro press fittings. I added a gall valve on the hot line so the system can be isolated if needed. Upon completion of the install I tested for water and gas leaks. The system is operating properly at this time.
