I you can call my contractor, Donnie, 347-444-3321, just say I recommended him, but would stay away from the buttermarks, they charged me $700 for the purchase and installation of a $100 part, gave me inaccurate information about my boiler mate hot water storage tank, and charged a senoir w/ a disability in my building $300 to replace the $25 flapper and handle on her toilet tank.
