The plumber and helper were on time and very professional. Explained the work, installed the tank and gas line, removed the old tank and cleaned up. They did a complete review of the operation of the new tank, pilot lighting if necessary, and annual maintenance/draining. Since this was a gas replacement for an electric tank, a building permit had also been issued and the installation was inspected and passed. The new tank is a nice improvement in hot water and operating cost over electric. I was aware of Sal's from Angie's List, but needed a larger tank plus gas line installation not covered in any advertised specials. The cost and service were excellent and I would recommend to anyone.
