Rescue Rooter installed a new Noritz tank less water heater, but the hot water was very slow in reaching the various faucets in my house. The plumbing pipes had been re routed several times, by the original installer, but things did not work right until I requested a different plumber. James N. came out and identified the problem, which was that a check valve was installed backwards. He fixed it, and we now have instant hot water. Good job!
