Why Do I Have Two Pumps in My Basement Waterproofing System?

Identification

• A sump pump removes water from the basement and drains it outside. These pumps are placed in the basement sump and are connected to drain tile in the footer. Water damage occurs when water drains into the basement sump but is not removed. This causes basement flooding. Two basement pumps are common in areas where flooding is a problem, especially during the rainy season.

Effects

• Having two sump pumps in the home is especially helpful when you are away from home for an extended time. Power failure may occur, disabling the primary pump. Backup pumps are battery operated and remove water if the primary pump fails. Keeping your basement free of water prevents mold growth and damage to your home.

Types

• There are sump pump two types used in residential homes. A pedestal pump has a motor located on the pedestal and the pump at the base. These type sump pumps are placed in the sump and must remain dry. Submersible pumps are meant to be submersed in water and are placed in the sump’s bottom. Either pump type is activated when water comes into the basement sump. The secondary pump only operates if the primary pump fails.

Considerations

• Sump pumps must carry water at least 20 feet away from the home. Do not allow water to drain into your neighbor's yard or into a septic drain field. To prevent dangerous gasses from seeping into your home, all sump pumps must have a cover over them. If you have two pumps in your basement sump, both pumps must have a covering.
