"The employees were professional and got the task done. We later learned that there was a mistake in installation of the new spigot. We promptly called the company who sent an employee out the next day and fixed it. We all make mistakes. So nice to work with a company that simply owned up to it, corrected it, and did not push back on us. Despite the mistake, we will choose them again for our plumbing needs."

"We were in a jam. We are attempting to buy our first home. We had our inspection scheduled and on the morning of, we learned of a potential plumbing issue. There was a report filed with the city stating that a couple of years ago there was some kind of sewer back up. This house is old, so I wanted to make sure we weren't signing up for any potential problems. I called around to local plumbers in the area. NONE of them were able to accommodate our need on this shortened time frame. I got Zach's number from a contractor friend of mine and in a last ditch effort gave him a call. Unlike some of the other plumbers I'd spoken with, Zach validated my concerns and informed me that he would recommend that I have my system inspected. He was very patient with my partner and I, making room for us that evening to show up in exemplary fashion. He did a full inspection of our sewer lines with a camera and explained to us what the different piping meant. He then tested our water pressure and advised us to request that the seller offer concessions to cover the cost of putting in a pressure reduction valve. He explained the reasoning behind his recommendations and took time to insure that we understood why he was recommending these services. He also took the time to explain and answer questions about potential upgrades as my partner wants to upgrade the hot water tank. He outlined different product options and explained with great knowledge and detail the differences between the products. I would highly recommend this company. If we get the home we will definitely be having this company come back and preform the necessary work that is needed for our new home."

"Had Groundworks install a drainage system and sump pump in our home’s crawl space. Anthony and his crew, Jordon, Uriel, and James were Outstanding. It was a three day job. They were on time every day and worked their tails off each day. It was a muddy job in cramped quarters. They never complained. Anthony kept me updated on the progress they made each day. Anthony shared pictures of the job as it progressed. They cleaned up the job site each day. Anthony went over all the details at the completion of the job and answered all of my questions. The whole process was Great. From the initial inspection done by Kristy to the office staff and the installation. The communication was also Great. I highly recommend Groundworks for a complete and thorough job."

Sump Pump Installation questions, answered by experts

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. 

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.

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.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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.
