"Perfect! Doug is an expert Plumber that knows private water system. He removed the old equipment and installed the new. Everything is still working great. The work was done almost 13 years ago. We used all Top of the line Gould Equipment. I probably should call Doug to replace it again because breakdowns with the water system can leave you stranded."
