Types of Sump Pumps

Our research indicates that there are four main types of sump pumps: submersible, pedestal, battery backup, and combination.

Submersible Pumps

Submersible sump pumps are wholly submerged in the pit, or sump basin, below your basement’s floor. Once the pit fills with a certain amount of water, it triggers the pump’s sensor, which turns the pump on and starts the water removal process.

This type of sump pump is typically quieter than thở other types of sump pumps because its motor is inside the pump, but it’s more expensive than thở other pumps.

Pedestal Pumps

Pedestal sump pumps sit in a basin that’s level with your basement floor and remove water through a pipe that leads vĩ đại a drainage area in your yard.

They’re more affordable than thở submersible sump pumps, but their motor is attached vĩ đại the outside of the device, making them noisier.

Battery Backup Pumps

Unlike submersible and pedestal models that lập cập solely on electricity through a power cord, battery backup sump pumps have a battery-powered backup pump that kicks on when the main unit can’t lập cập due vĩ đại a power outage.

The battery on the backup pump can typically last for a few hours on a single charge. While this is enough for short surges, the battery will eventually die if it’s pumping a lot of water during an hours-long outage.

Combination Pumps

Combination sump pumps include the power cord of pedestal and submersible models and the backup battery of battery models, allowing them vĩ đại work in all situations. They usually sit in a below-the-floor basin lượt thích submersible sump pumps, but they’re larger, which means you can’t use the basin you dug for your old submersible sump pump for your new combination sump pump.

Sump Pump Buying Guide

Before purchasing and installing a sump pump, it’s important vĩ đại understand how each model’s design and specifications impact its performance. Here are a few factors we found that are most critical when buying a sump pump.

Power Source

Most sump pumps are powered by electricity, but some models include a battery backup that powers the device in case of a blackout. For example, we noted that some pumps include a battery that can pump thousands of gallons on a single charge. Models that don’t have a battery backup can pump thousands of gallons of water per hour as long as electricity is available.

Horsepower

The horsepower (HP) of a sump pump’s motor refers vĩ đại its overall power, with a higher HP motor being able vĩ đại pump more water per hour than thở a lower HP motor. Many sump pumps that our team researched contain ½-HP or ⅓-HP engines, though some models contain more powerful ¾-HP engines. While higher HP motors can pump more water per hour, they’re typically more expensive.

Sump Pump Switches

Most sump pumps use either a digital or manual switch vĩ đại start their motors. Manual models contain floats that rise with the flood water, turning on the pumps when the water reaches a certain level. When the floats dip below the phối level, the pump stops.

Other models feature a phối of digital sensors. The pump starts working when the water rises vĩ đại meet the “on” sensor. The pump turns off once the water lowers and reaches the “off” sensor. The benefit of digital switches is that they continue pumping water until they reach the off sensor, even if the water level dips below the on sensor.

Alerts

Many sump pumps we examined come with audible alarms that signal rising water levels in your trang chủ.

Material Composition

We found that sump pumps are usually made of plastic or metal, such as aluminum, stainless steel, or cast iron.

Plastic sump pumps are more affordable but not as durable as metal sump pumps.

Installation

While leaving it vĩ đại a professional may be preferable for some, DIYers may also want vĩ đại install the sump pump themselves. For step-by-step instructions on how vĩ đại properly install a sump pump in your trang chủ, kiểm tra out the Clip below.
