Recent Review: "My experience with James A. Douglas Plumbing & Gas Fitting was nothing short of fantastic from beginning to end. From the start, they were very responsive to my emails and/or texts. They talked me through several possible remedies for me to try to resolve my situation before I made the decision to finally replace my hot water heater. There were no high pressure sales tactics or attempts to add on unnecessary parts or services. The technician, Zac, who came out to install the new hot water heater was extremely professional and friendly. He also took the time to explain everything in a way I could understand it. James A. Douglas Plumbing will be my go to for any future plumbing needs," --Josh Peters Thank you for supporting our company, Josh! We'll make sure Zac hears your praise!

Trivia on Tap: Happy President's Day! To celebrate, we're wiping away the grime on a tall tale about President William Howard Taft. It's been said that President Taft got stuck in a White House bathtub and had to be buttered out, but that’s actually a myth. In fact, just after his election Taft had a custom porcelain tub installed that was big enough to fit four grown men! However, while he never got stuck, he did cause a bit of a plumbing catastrophe two years after his presidency ended. In July 1915, Taft was staying at a hotel in Cape May, New Jersey and over estimated the amount of water needed for the tub. When he got in, so much water was displaced that it trickled onto the heads of guests in the dining room below! The next day as Taft looked out onto the Atlantic ocean, he was quoted saying "I’ll get a piece of that fenced in some day, and then when I venture in, there won’t be any overflow," From clogged tubs to leaky pipes, we'll be sure to make sure your plumbing can handle a 'presidential' soak! Just Call James to set up an appointment!
