"My service technician, Mason, arrived on time and got straight to work. He was very thorough and explained everything that he was doing as he was doing it, and prior to doing it. He arrived with another associate, and both men were very nice. I like the fact that they’re thoroughly explain everything and don’t try to pressure you into buying anything at the very end. He fully explained that in a few months I would be due for another filter, but that everything else was OK. He also explained what would happen if I did not change the filter which was helpful. I would highly recommend Cardinal if you are in need of heating or air conditioning repair or service."

"Well pump system was failing. Theo gave a quick and accurate analysis of problem. There was no pressure to hire them. The problem needed correction ASAP. They did excellent work and completed it on the same day as the quote. I only wish I had more time to get more quotes or I would have given them a 5 star value for money rating."

I initially had a poor interaction with Mike that did not result in solving the above plumbing problem above. However, he has since connected with me and resolved the issue fairly.  He did an excellent job the first time I hired him (successfully unclogging a tub drain). Even though the second time we hired him was not successful (and we had to hire a second plumber to resolve the problem) we will use him in the future because he reached out to resolve our concerns in a professional manner.

FAQs for sump pump or interior foundation drains installation projects in Watertown, WI

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.
