Sump Pump Installation questions, answered by experts

Costs range from $300 to $1,200, depending on the pump type, issue, and installation complexity.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

A sump pump should be placed at least three feet deep in a pit. The rim of the sump pump basin should be level with your basement floor. If you find your pit is too deep, you can fill the bottom with gravel until the rim of the sump pump is flush with the floor.

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.

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.
