Foundation Drain Installation FAQs, answered by experts

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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

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.

Installing a sump pump takes a bit of know-how, but it is possible to do it yourself. You’ll need to familiarize yourself with details like where sump pump water goes to avoid creating new flooding risks. If you’re doing the work yourself, it’s recommended to bring in a pro for a quick inspection afterward so you can be sure your home is protected from any water damage concerns.
