3 Things To Look For When Choosing A Sump Pump

A flooded basement, weakened structure, ruined possessions, mold contamination—the list of possible consequences is long. Because a sump pump typically spends most of its time on standby, silent malfunctions often don’t become obvious until water intrusion happens and the pump fails to respond. The risk of a sump pump failure just when it’s needed most can be reduced by making informed buying choices. Here are three things to look for when selecting a sump pump:

Battery Backup
A sump pump that relies solely on household AC electrical power is a risky bet. The fact is, many scenarios that require the protection provided by a sump pump—such as severe storms and flooding—also tend to be common causes of utility power failures, as well. This means that an AC-powered pump could fail to function just when it’s needed most. Sump pumps that also incorporate a DC battery backup option will actuate to pump water out of the basement even if the power grid goes down. This adds a vital extra layer of protection.

The Right Size
The “size” of a sump pump means its pumping strength expressed in horsepower. For an average residential basement with only intermittent water intrusion, pick a pump with at least 1/3 horsepower rating. If your basement has ongoing water issues—such as a high natural water table beneath the foundation—or if the basement extends unusually deep below ground level, you may want a 1/2 horsepower unit.

Pedestal vs. Submersible
Pedestal sump pumps are mounted on the floor above the sump basin. An inlet pipe extends down into the basin to suck out water. However, submersible pumps installed inside the basin are now considered more efficient and reliable. Because the entire pump unit is directly submersed as water enters the basin, suction is more positive and effective. Submersed pumps also run cooler, which means longer service life and fewer potential malfunctions.
