"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"

Sump Pump Installation questions, answered by experts

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

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

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

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.

One common reason a sump pump stops working is improper sizing. Different locations need different sizes and power ratings of sump pumps depending on the typical amount of water the pump needs to manage. If your sump pump is too small for the quantity of water, it can overwork and either burn out or reduce the life of the unit. If the pump is too big, it can overwork and burn out early.
