"I had an issue with my drain backing up. Received excellent service from drain pro. The consultant was available to chat with me at 8pm and guided me correctly. He came to inspect the issue in the morning and found that the issue was much easier to resolve with a pump and ended up not charging at all."

"Harts Services reached out to me on Friday regarding my request and was on the schedule for Monday morning. Steven arrived on time, was professional and considerate of my personal space. He got right to work identifying key issues and provide multiple options. Found out that we had an sump pump that failed and recommend we replace that 1st. Everything was replaced and tested within 40 minutes."

"Water had always been a problem for my crawlspace, especially during raining and snowing season. Asking around, installing a French drain and a sump pump appeared to be the solution. I searched around and picked Insulation Co. Estimation without inspection seemed weird at first, but it made totally sense since the foundation layout is all there in the files. Jo had always been responsive, detailed and nice whenever I had questions. Scheduling was easy and Rafael and the team did a great and efficient job onsite. 2 months after the installation, we noticed that there was still standing water and they came back to install more pipes and gravels. We really appreciate the effort."

"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"I was aware that we needed to replace our water heater and took advantage of the deal on Angie's List. Because of summer vacation schedules, I pushed off the installation for several weeks. While I was on vacation, they contacted me that they had some vacation schedule issues for the week of our planned appointment so when I returned home, I rescheduled the installation to yesterday with a two hour arrival appointment. The office confirmed our appointment the day before and the technician called before the arrival time to let me know he was running behind and gave me an estimate of when he would arrive, and again called to tell me the exact time he would be here (I appreciated that they kept me informed and he was only an hour later than originally planned). Interestingly, the appointment was fortunate since our water heater had pooped out the night before! The technician arrived, very professional, and we talked about what he was planning to do before he started, made recommendations for replacement of some of attached equipment and the reasoning why replace, and what the cost of those replacements would be before he started, and gave me an estimate of how long the installation would take. When he finished, he went through the completed equipment with me and left a clean worksite. Trace was an excellent representative for the company. I would use this company again if needed."

"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 FAQs, answered by experts

There are several things you can do to maintain your sump pump and prevent sump pump problems. For instance, keeping a lid on your sump pit goes a long way in protecting your pump system from silt, sand, dirt, and other debris. When water drains from the outside, such as along your foundation, or with melting snow, water runoff often brings sediment with it. 

Also be wary of corrosion, particularly if your sump pump system is made of metal. Keep an eye out for rust and have it inspected regularly by a plumber or sump pump technician.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.

3/4 HP is stronger than 1/2 HP. Horsepower measures how much weight can be moved and how fast, or the power needed to move 550 pounds one foot in one second. 1 HP equals 550 foot-pounds per second, so the higher the horsepower, the heavier the load it can lift. While 1/2 HP is a standard, powerful option, 3/4 HP has the extra strength to handle heavier, larger doors with ease.

Sump pumps remove excess water from the lowest point of your home, which prevents flooding. When a sump pit fills with water, a sump pump pushes that water outside of the basin and into an exterior discharge pipe. From there, the water flows away from your home, so it doesn’t damage your foundation.

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.
