"KJM Plumbing, Kurt, responded quickly to my request for a quote on replacing our leaking water heater. He quoted installing a high quality, Bradford White unit at a reasonable price. The plumber who did the full installation was a very skilled, professional and friendly worker. The final invoice had no unexpected charges and included a nice breakdown of the major portions of the project. I highly recommend KJM Plumbing, for work in the Madison, WI area."

"I purchased a new HVAC system from Cardinal. Everything about the job went as planned, in the amount of time we were promised. The installers were professional and cleaned up the work space very well when they were finished. I would use Cardinal again without hesitation."

"Lucas was amazing to work with. Got us a deal on a new kitchen sink and offered a match on the faucet when we found it cheaper elsewhere. Very prompt and excellent service. Will definitely hire again in the future."

"The plumber was very friendly and professional. The price they quoted me was over $200 less than other plumbers for the same level of service. I was very pleased with the competence of the plumber. He took the time to explain the controls to me, the type of salt I should use, and how much salt for my new water softener. He was an hour late, however he finished the job in less time than I was quoted."

Sump Pump Installation FAQs, answered by experts

The most common cause of a clogged sump pump is natural debris buildup. As water enters the sump pit, it can carry small pieces of debris that build up over time, or the debris can get caught in the filter. If you forget to cover the pit after cleaning the sump pump and pit, debris can also collect in the pit. Corrosion on the metal discharge pipe can also clog the pump. Additionally, if your pipes freeze, it can prevent water from draining properly and cause a clog.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

Yes, a well-maintained sump pump can increase a home's value and make it more desirable to potential buyers; it does not lower property value. By protecting the basement from flooding and water damage, a sump pump provides peace of mind and can make the space usable for storage or as an extra room. For buyers interested in homes with basements, a working sump pump is a significant feature that adds value by ensuring the space is secure and less likely to flood.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.
