"The Plumbing Authority got back to me right away once I connected with them on Angi. We agreed on a date and time for them to come to my house and they were there exactly when they said they would be. Mikhail was very polite and professional and didn't try and "upsell" me anything. He kept the area that he was working in clean and when he left you wouldn't have known he was ever there except for the leak problem had been fixed. He completed the work very timely. I like The Plumbing Authority very much and would highly recommend them. "

"SMK plumbing did a great job for me with a whole house water re-plumbing & main water line from the street. The team was efficient, professional, and polite. Job was started and completed in one day. They even moved the whole house shut off and pressure valve to a very easy to get to location."

"Jon did a timely, quick, thorough job. And this, after hours. Had he not fixed us up after the workday ended as he did, we would have either been without water overnight or paid our water company to spill 3 gallons per minute down our street. Get Winkle’s Plumbing whenever you can. They’r grand."

"We called Mr Appliance in June to help with a smell in our dishwasher. At that time the tech told us he found what he thought was the source and remedied it. He also informed us that if the smell comes back within a year it would be covered under warranty. Fast forward 3 months later, the smell is back. When we called to ask about a followup visit they proceeded to say it was not covered under warranty and charged us another $140 to come out for diagnostics... okay, cheaper than a new dishwasher, please come out. On scene the new tech tells us he cannot find anything wrong. Proceeds to tell my wife to clean it more often then charges us another $50 for customer consult. $190 later we're in the same spot + a HUGE scratch on our hardwood floors. Would not recommend. I am in the process of following up for refund of the $50. 😡"

FAQs for sump pump or interior foundation drains installation projects in Knoxville, TN

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
