"I'm not fully moved into the home yet, but I will update when I am there permanently. The crew was very professional, worked diligently, cleaned up after every day of work (three day job--french drain expansion, two additional sump pumps installed, window drains into the sump pumps, pretty extensive job)."

"Amazing! The crew was on-site within 3 hours of my 8:00 AM phone call to replace my sump pump. My sump pump runs every 15 minutes, on a dry day, so it was critical to get expedited service and Delaware Plumbing Professionals were fantastic! Highly recommend"

"The team was very knowledgeable and helped explain my options. Gave me upfront pricing for each option so I could weigh those options before proceeding with a sump pump replacement. The parts were delivered and installed on the same visit. It helped keep my basement dry."

"I had a wall in my basement that was filing up with water from runoff outside. The wall started leaking into my basement. The crew jackhammered a trench along the wall in my basement and installed a drainage pipe, fill and a sump pump. They cemented over the trench and it looks like they were never here. Lots of rain since then and my basement is dry. Timely and professional- highly recommend"

"We had numerous issues with water in our basement in the 5 years we owned our home, it was not an easy fix and we received numerous ideas and quotes. The rep from Worthington came out and was amazing, did not try and up sell us, and identified and fixed every problem. Worthington was not the cheapest firm we spoke with but would you really want the guy with the lowest price for a job like this? We would recommend this company emphatically."

Sump Pump Installation FAQs, answered by experts

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.

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.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.
