"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"4 other plumbing contractors suggested I replace my sump pump becauae it was 30years old without even seeing it. Another said he would come to evaluate for349.00, but would then return to repair for an additional cost. A tenant had turned off the outtake valve causing fuse to pop. It's nice to know that there are still honest people out there. Thank you for prompt and honest service. Highly recommend."

"Our technician, Dameyan Jackson, called the night before the day of service to let me know the time that he would be here to service our system. On Friday, he called to let me know that he was available to come earlier than scheduled, if I would like. He arrived shortly after the phone call, came in and quickly recognized that the pump had failed. He was very knowledgeable and professional. I was very pleased with his service and look forward to him returning to install a new pump."

Sump Pump Installation questions, answered by experts

Several indicators suggest it's time for a sump pump replacement. A key factor is age; if the pump is over 10 years old, its lifespan is likely ending. Performance issues are also clear signs, such as the pump running constantly, cycling on and off frequently, making unusual noises or vibrations, or failing to function at all. A faulty or burnt-out motor is another definite sign a replacement is needed. Additionally, if you notice any signs of incorrect installation, the pump should be replaced. For a definitive diagnosis, a vetted plumber can assess the pump and confirm whether a replacement is necessary.

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.

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.

You shouldn’t shower while a sump pump isn’t working. Although household wastewater isn’t supposed to go into the sump pit, it’s best to wait to shower until your sump pump is running properly and able to move excess water out of the basement. If you need to shower when the sump pump isn’t working, aim for a short shower.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.
