"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."

"I forgot to do this review but am glad I did because I am two years out having waterproofing services by this company. The drain and sump pump recommended by Robert Ellis is absolutely worth it. I no longer am anxious about weather forecasts because of the work done. Robert evaluated my home, gave me options and soft recommendations then allowed me space to make the best long term decision. Completely satisfied and would 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

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

Yes, it’s possible to install a sewage ejector pump outside rather than in a basement. However, there may be some extra steps involved, including running pipes from the inside to the outside of your home and digging (and re-filling) a hole for the basin. If you aren’t comfortable with this type of work, contact a plumbing pro to handle it for you.

Some sump pumps are powered by water rather than electricity. Water-powered sump pumps generally use one gallon of city water to pump out two gallons of water from its basin. Therefore, if you're looking at a potential 10,000-gallon flood, your sump pump will need to use 5,000 gallons of city water to prevent it.

Yes, many providers offer warranties for new pumps and labor. Confirm terms before scheduling.

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.
