Sump pumps are used for removing groundwater from basements and crawlspaces. They can be fully submerged in water.

Sewage pumps are used to lift household sewage water from a collection basin and send it to a gravity-fed sewage line or septic system.

Utility pumps are used for removing water from flooded areas, spas, and window wells. They can be fully submerged in water.

Transfer pumps create suction on the inlet hose and are used for moving water from one place to another. They cannot be submerged in water.

Well pumps are used to draw water from a well or cistern that is less than 25 feet deep. They are connected to a pressure tank system and run automatically with a factory-installed pressure switch.

Lawn sprinkler pumps are used to draw water from a cistern or natural water source that is less than 25 feet deep. They can supply up to two conventional sprinkler heads for typical watering applications.

Gas Engine pumps are used for outdoor water removal. The clear water, semi-trash, and full trash descriptions indicate the type of debris such as mud, rocks, sand, and sludge that can pass through the pump without clogging it.

Fountain and Pond pumps are used for decorative water features. They are intended for continuous run applications.
A pump that is labeled “submersible” can be submerged completely underwater. However, the pump must be plugged into a GFCI protected outlet to prevent death or serious injury from electric shock.
A manual pump must be manually turned on by plugging it in and turned off by unplugging it (or with a switch if equipped this way). It requires the user to remain with the pump and monitor the pump flow, so that they can turn it off when the water moving task is finished; otherwise, the pump will run dry and be damaged. An automatic pump is controlled by a switch that is linked to a float, electronic sensor, or pressure device. This type of pump can turn on and off on its own without a person monitoring it.
This may be due to an “airlock” condition. This means a pocket of air is trapped around the impeller. The impeller is the rotating part connected to the motor that generates water pressure and flow. A trapped air bubble will keep water away from the impeller vanes, preventing water from flowing out of the pump. If you have a utility pump with an airlock condition, unplug the pump and tilt the pump to the side to release the air bubble, reset the pump into position, plug in the pump, and watch for output flow. If you have a bottom suction sump or sewage pump with an airlock condition, refer to your operator’s manual for instructions on drilling a 1/8 – 3/16-inch diameter vent hole in the discharge pipe to release the air. Be sure to drill the hole in the area above the pump discharge port and below the check-valve.
Pumps can build pressure to lift water (measured in feet of head lift), or they can create flow (measured in gallons per hour – GPH). Pumps can also do a combination of lifting and flowing with their output power. If a pump uses more power for lifting water, it means there is less power to create flow. A pump Head versus Flow chart shows how a pump’s output flow will decrease as it uses more power for lifting. Hose/pipe length, reducer fittings, and elbow turns will increase head lift and therefore reduce output flow.
If the motor is humming but there is no water flow, the impeller may be jammed. To check and remove a jam, unplug the pump, and remove it from water. Then remove the inlet cover plate with a screwdriver and clear any debris. Rotate the impeller by hand to ensure it rotates freely. Finally, replace the inlet cover plate and screws, place back into the water, and restart the pump.
