"This was our first time using Sila and we are very impressed with the quality and professionalism of their service. When I made the initial appointment they quoted me a price for the service and said they would contact me 24 hours before to confirm. Like clockwork they called to confirm. The day of our appointment service tech, Kyle, showed up 10 minutes early and got right to work. He carefully checked out our 3 HVAC units and our heat pump and changed all filters and associated service needs. Charges for the service call were as quoted (plus the costs of the filters). All in all we are very happy with the service (and Kyle's professionalism) and will definitely hire them again for all of our HVAC needs"

"Amazing. YES - you pay a lot - but they rocked, their solution rocked, and the installation was flawless. We just built a brand new home and the builder put in the cheapest 24" deep sump pump possible. We live in an area known for basement flooding so I did my research - had several companies come in - and settled on Connecticut Basement Systems. But my LORD - expensive. But now I know why. Their crew of 3 showed up and laid down plastic mat from our front door all the way down to the basement (at least 200'). It was over kill - but then I saw why. They had to dig a 36" deep pit and a wider hole - and brought up all the mess in buckets. NOT A SINGLE DROP ON THE BASEMENT FLOOR OR ONE THE WAY UP THE STAIRS. In fact - if you didn't see the high tech 3 pump sump pump they installed - you would have never known they were there. EVERYONE was super nice and answered all my many questions. I just spent a year in **** building a new home - and this was the best experience I've had with a contractor in 10 years. Pay the bucks - great product - great installation - great service."

"I hired Rich Because he took the time talk to me and explain the job and give me solid information. The hot water tank installation was very quick, efficient and neat. Rich and his co-worker were friendly, polite, and mindful of my cat not getting out. I highly recommend E and R Plumbing!"

"Eco Flo Plumbing spent a lot of time preparing an estimate for me. The company also made two visits to my home for thorough inspections of my job site. The price quoted to me was fair and reasonable, and the sales person was extremely personable! I Wholeheartedly Recommend EcoFlow !"

Sump Pump Installation questions, answered by experts

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

The cost to repair a sump pump ranges from $400 to $550, depending on the extent of the repair and your location. Minor repairs, like fixing a switch or replacing a float, can cost just a few hundred dollars. However, more significant issues, such as motor replacement or addressing electrical problems, may cost closer to $550. Keep in mind that regular maintenance can help prevent costly repairs, and if a sump pump is beyond repair, a full system replacement ranges between $650 and $1,400.

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.

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. 

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.
