"Thank you, your water filtration system is a perfect fit for our house in Reston VA. Worked with Randy who made free water test and recommendation and had the system installed by young man Matchett. Working with both gents was a real pleasure: they were in time, professional, did not waste my time, were right to the point. Installation was a breeze, received good recommendation, system works great, had another free water test after system was installed. Very happy with results. Strongly recommend."

"Tommy B was efficient and courteous. I knew who to expect since I got the name and a photo of the plumber in a text. He covered his shoes upon entering the home. He gave the price for parts and labor upfront. He replaced my old sump pump with a new Zoeller Sump pump. As he was working he patiently answered my questions. He cleaned the work area thoroughly. Excellent job."

Sump Pump Installation FAQs, answered by experts

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.

If your water pump fails, the first step is to turn off the power to the pump to prevent any further damage. Check for common issues such as clogs, electrical problems, or mechanical failures. If you cannot identify the problem, contact a professional who specializes in pump repairs. Prompt action can help minimize damage and repair costs.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.
