What Is a Sump Pump?

A sump pump collects the water from around it as well as from drainage systems to safely pump the water out and away from a homes foundation. This important piece of waterproofing keeps spaces from flooding or standing water. You want your sump pump to operate when you need it, so to help our customers we use Zoeller Sump pumps for their reputation of longevity and reliability. They are the #1 choice in A/C submersible pumps by This Old House, Pump that Sump, a Sump Pump Review Site, and Sump Pump Problem.

Choosing a Sump Pump - Recommendations from Bob Vila

If your water problem is serious (e.g., a high water table that gets higher when it rains), there’s no getting around it: you’re going to need a sump pump. Here are some quick tips on choosing the right one for your needs:

• Choose a submersible pump over a pedestal pump. Submersible pumps allow the sump pit to be covered with a lid, reducing pump noise and stopping debris from falling into the pit. An airtight lid also helps keep moist air from being released into your home.
• Buy a pump with a cast iron core, not one made of plastic. Cast iron helps to dissipate heat to the surrounding water, lengthening the life of the pump.
• To minimize the chance of clogs, the pump should have a no-screen intake design coupled with an impellor that can handle solids up to ½-inch in diameter.
• The switch should be mechanical, not a pressure switch, and the float should be solid so it can’t become waterlogged, fail to switch off, and burn out the pump.
