"Jeff, Rob and his crew were exceptional They answered all of my questions even took the time to show me how things worked. They installed a water catch basin and sump pump to replace our smaller 25 year old equipment. Jeff suggested a better pump They were meticulous in their work and cleanup except for the new pump you would not even know they're there. I would recommend ONCE&DONE for any of your waterproofing needs Thank you ONCE&DONE"

"HIGHLY RECOMMENDED!!! We just had a French drain installed along with a new sump pump and pit in our basement and had the floors epoxyed afterwards. The project manager, Kenny, was absolutely amazing. From the very beginning he explained everything that their team would be doing, gave me updates throughout the day. If I had a question or concern Kenny was patient with me and continued to make sure any questions/concerns were addressed, even telling me to call him if I thought of any other questions. Their crew was very respectful of the property by making sure to lay out tarps to protect the floors, and made all attempts to manage the noise since we were home. Whatever was left in the basement they made sure to cover and protect. And if something needed to be moved they moved it and moved it back. When it came time to lay down the epoxy there was a scheduling hiccup. Kenny though went out of his way to make it right by coming right after another job and staying late to make sure we're stayed on schedule since I was having out of town guests coming that weekend and needed access to the basement. Working with Select Basement, but especially Kenny, made this one of the best experiences and I highly recommend them. 10 out of 10!"

Sump Pump Installation FAQs, answered by experts

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

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.

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.

If you have a self-cleaning washing machine but you’re still seeing lint, your water pump filter might be clogged. To clean it, you should unscrew the drain hose, then remove the water pump filter. From there, you can inspect it and clean it with warm water before replacing it. Check to be sure your washing machine is functioning by running a short cycle. 

Repairs typically take 1-2 hours, while replacements, depending on accessibility, may require up to 4 hours.
