"Service tech arrived a few minutes early and got right to work. He diagnosed the problem very quickly and then replaced the sumo pump and waited until it had fully drained the sump pit. Overall excellent work!"

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"I had a clogged kitchen drain on a weekend, a challenging time to find a reasonably priced plumbing company. After several unsuccessful calls, I made an appointment with an expensive service for the same day. I received a call back later in the day from Jason at Afford-a Router. He answered my questions and made an appointment for the same day. He arrived at the house, reviewed and resolved the problem in twenty minutes. He was professional, answered my questions, and the charge was very reasonable, considering it was a weekend. I highly recommend their services and will use them again."

"The plumbing installation for the new shower went very well. Our plumbing technician was a journeyman which really gave us confidence that the work would be excellent. The company offers reasonable pricing and was great at helping us figure out the best course of action. I will be working with them again."

FAQs for sump pump or interior foundation drains installation projects in Boulder, CO

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.
