Precision Plumbing, Heating and Air did an outstanding job installing our new tankless water heater. It was a tight location where a normal water heater would not fit and they were able to come up with a solution that worked for us. Liz was great to work with in the office and Marcus did an amazing job with the install. They both understood our situation and went to Great length to make sure that the solution fit our needs. We are a week out of having the unit installed and so far we are very happy! I would highly recommend Precision Plumbing heating and Air/ Watts Plumbing if you are looking to have a new tankless water heater installed.
Mammoth Plumbing's reply
