"Equipment, which is hard to come by these days was set aside for my job once contract was signed. Schedule and arrival was a very smooth process with plenty of communication in between. Sales/estimator was professional as was the installer. Left both work area’s clean."

"The specific project completed on our home was to provide drainage, including a sump pump, in our crawl space and to replace the vapor barrier. Although our particular project was very difficult, including a clay surface below the old vapor barrier, the crew managed to prepare the drainage pipe ditch and lay perimeter drainage pipe. They labored with soil that was either too wet and therefore too sticky to work with a shovel, or soil that was too dry and almost rock hard. After many days of effort they managed to successfully install pipe, sump pump and vapor barrier. In spite of the very difficult conditions with which they struggled to complete the project, the crews who worked on our project were very courteous and professional in the way they did their job. I would highly recommend Josh Lowe's Dr. Energy Saver Home Services."

Sump Pump Installation FAQs, answered by experts

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

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.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.

Sewer ejector pumps need to be cleaned at least once a year by a professional. You shouldn’t attempt to clean it yourself because it can release sewer gasses that are toxic to humans and can be fatal. But to keep the system as clean as possible between professional inspection and cleaning services, be sure to only flush human waste and toilet paper. Avoid flushing items that can clog the system, like paper towels, grease, oil, or menstruation products.
