My water heater and PRV failed (and flooded the lower level). I actually called Renée and Joe from TAPP Plumbing, who I had used for years, to find out they had merged with Techmazing. If they were good enough for Renée and Joe, they were good enough for me!

Eric is amazing at what he does. He came in accessed my equipment told me what was wrong and how much they would cost. He was very knowledgeable and kept me laughing the entire time he was here. Please send him back again if we ever have issues. I work at McDonald's and he did not play about what needs to be fixed.
