"very professional, punctual, and thorough installed an internal french drain system including demolition work and sump pump and backup sump pump with dehumidifier. Bulk of work done within 2 days, balance of work to be down when weather warms up and ground is soft enough to place drain outlet pipe and down spout extensions underground"

"It went well. They are being professional in their follow-up as they are trying to have us install an expensive basement drainage/pumping system. We haven't decided yet, as it will be part of our basement gut/rehab project."

Sump Pump Installation questions, answered by experts

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

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.

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Costs depend on pump type, labor rates, and the extent of repairs or installation needs.
