Important Features
Sump pump features can be broken down in to eight categories. If you understand these categories you will be much better equipped to make the correct choice for your next application. Good pump-reviews will tell you what operates each sump pump, the type of construction material, the intended use, pump specs, the discharge size, if it stands up to dirty water or sludge, and finally how much energy it will use over the course of a year.

Operating Systems
Let’s take a look at the different types of operating systems. Automatic sump pumps are activated based on either a rise in water level or water pressure. Here’s a comprehensive list of pump activators.

Tether floats are attached to the outside of the pump and move according to the water level. If the water level rises, this float will rise and turn the pump on. This type of float is usually found on cheap pumps and require more maintenance.

Vertical floats are composed of a steel rod with a sliding ball and operates the same way as the tether float. As water rises and falls, so does the float which turns on or shuts off the pump. Plan on replacing the switch to a vertical float often.

Diaphragm membranes are connected to a disc like component that sense water pressure. Unlike the previous two floats, this float is activated by water pressure due to the disc or drum mechanism changing shape. This mechanism is very reliable unlike the tether and vertical mechanism.

The probe activator is like the diaphragm in that it is activated by water pressure through an electronic sensor. Equally reliable as the Diaphragm.

Pump Construction
Cheaper pumps that have a shorter life span are always made of plastic. If you’re on a budget, plastic pumps are good solution. Any top quality pump will be constructed of either cast iron or cast aluminum making them the preferred choice. They are more expensive but will last a very long time.

Water Discharge
Each pump has its own horsepower rating. More horsepower means more water can be pumped per minute. This is important if you need to pump water up long pipes from a basement to an outside drain. You use more electricity with a high powered pump. A shorter distance will require less power and therefore less energy consumption. Common horsepower will range from .25 to .75.

Discharge Diameter
Small discharge diameters will decrease output per minute whereas larger discharge diameters allow for maximum output. This is important understand because pumps are rated to move gallons per minute not just on horsepower but also discharge diameter.

Energy Cost
Just about all new sump pumps are built for energy efficiency.

Warranty
You’ll find each manufacturer has one of the following warranties. Either no warranty at all, 1 to 5 years, limited lifetime, or a full warranty for life. Obviously, the best sump pump will come with a solid warranty. You can trust such a pump because you know the company building the pump stands behind their product.

Here’s a quick guide to help you determine which sump pump you need.

<If you live in a heavy rain region and your sump pit fills up quickly you’ll need a stronger pump with more horsepower.

<A common issue is having to replace the float switch. Some pumps allow for replacement without removing the pump from the pit. If you don’t want to life the pump out of the pit, especially if your pump is heavy, consider this important point.

<When reading sump pump reviews, keep this information in mind to make the best decision.
