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!

Trivia on Tap! There is a long-standing urban legend that claims sewer systems across the country face their biggest test during the Super Bowl Halftime Show. The story goes that millions of fans, glued to their screens during the first half, all rush to the bathroom the moment the whistle blows. The fear is that this simultaneous "mega-flush" creates a surge so powerful it bursts pipes and overwhelms city sewers. It is a dramatic image— But luckily, it's also a myth! While it's true that water authorities monitor systems for these spikes, the "Super Bowl Flush" is a myth in that modern sewer systems are built to handle a massive volume. Even so, the water usage data is fascinating! Water authorities consistently record significant drops in water pressure and massive spikes in sewage flow exclusively during halftime and immediately after the game ends. It is one of the occasions that human behavior is perfectly synchronized by a television event. Fortunately, your home plumbing and the city main lines should have handled it just fine, but if you ARE experiencing plumbing problems we would be happy to help fix them!

We celebrated our Lead Technician Zac's workiversary last week, and we thought it was the perfect excuse to turn the spotlight on him. In this issue, we’re sharing a special 'Insider Scoop' Q&A so you can get to know the person taking care of your tech a little better! Q: What is the one tool you absolutely could not do your job without? A: A tiny crescent wrench I keep in my pocket. It's fully adjustable so I can use it on EVERYTHING, water lines, taking apart faucets and shower heads, putting new blades on our saw, you name it! Q: What is your favorite type of job to work on? A: Trim outs (that's when we install all the fixtures in a bathroom) because you can make it look all fancy and nice Q: What's your go-to snack food? A: I'm a gummy kind of guy. Sometimes during work we'll stop at 7-11 and Will will get food but I'll just pick up a bag of gummies Q: What is your favorite local restaurant? A: It's not really local since it's a chain, but my wife and I love the half apps at Applebees. I'm open to suggestions if you have any though! Q: If you could travel anywhere in the world, where would you go? A: I'd have to say Sweden for the snow, I love snowboarding Q: If you were an animal, which one would you want to be? A: A Mouse. No further context needed. Maybe a slight upgrade to rat Q: What's the weirdest gift you've ever received? A: Ever since becoming a plumber, the amount of plunger-related gifts is insane. I've got at least 3 mini-plungers now. Here’s to many more years of Zac helping things run smoothly at JAD!

Trivia on Tap: Did you know that Albert Einstein is famously quoted saying: "If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances." In the middle of the McCarthy era, Einstein felt that scientists and scholars faced unwarranted scrutiny and admired the freedom professions such as plumbers and peddlers retained. His letter to the newspaper explaining just that, resulted in him receiving an honorary membership to the Chicago Plumbers Union!  Announcements: This area is expected to get snow this weekend so make sure you are prepared! If you notice anything out of the ordinary with your plumbing or gas fitting equipment, let us know ASAP so we can get to it before the storm!
