How does a sump pump work


Over time, we have received many questions from our readers regarding the way sump pumps work. This is the reason we eventually decided to create a comprehensive article that manages to provide answers to some of the most ardent questions one might have about these machines.




How does a submersible sump pump work?

Unlike their pedestal counterparts, submersible options have to be installed underwater. The simplest way to explain how these models manage to do their job is by noting that all units, regardless of their specifications or power, come with a unique sensor that lets them know when the water has reached a certain level and it should start being removed. An impeller is what makes it possible for the pump to discharge the liquid into a pipe or hose in order to get it as far away from the cellar as possible. The core reason this type is popular among homeowners is that it is reasonably quiet.


How does a pedestal sump pump work?

The main difference between a submersible and a pedestal model is that the motor of the second is not underwater. In order to remove the water that might affect your home or basement, a pedestal sump pump needs to actively suck it out of the sump pit and direct it toward your sewage system. Most models need to rely on the use of a vertical float switch in order to do what they’re supposed to do.


How does a sump pump float switch work?

The float switch modifies its location when it automatically detects a flooding in the sump. This makes it possible for the pump to start operating as the switch will not return to its original location unless the pump manages to empty the sump. Once the switch has come back to its regular place, the pump can stop working.


How does a sump pump work in a basement?

It depends on the type of sump pump you plan to install or you might already have installed in your cellar. If the unit is submersible, it comes with a sensor that gets the sump pump going when the water has reached a particular level. If you own a pedestal alternative, there’s a high chance that it comes with a float switch that does the same thing with regard to “telling” the pump to get to work by modifying its position.


How does a water powered sump pump work?

Water powered sump pumps rely on the owner’s municipal supply. Most models require one gallon of city water in order to be capable to discharge two gallons of water that must be removed. The functioning principle of such a sump pump relies on the Venturi effect. Because a high velocity jet is created at the throat of an ejector nozzle with the help of water coming from the municipal system, the low pressure that results from this process makes it possible for the system to draw the sump water into the nozzle. In the end, a combination of city water and sump water will be eliminated by the water powered sump pump.


Does a sump pump use a lot of electricity?

Water powered sump pumps don’t need any electricity to speak of, but submersible and pedestal alternatives do need power all the time. It’s difficult to give a straight answer to this question because it all boils down to the performance of the model you own. If you were to use a sump pump with a 1 HP motor for six hours every day, you’d consume about 300 to 400 KWH extra per month. Nonetheless, most automatic sump pumps turn themselves on when their services are required, and unless you live in an area that’s affected by heavy rains all the time, you won’t see a big difference in your bills.


How does a fish tank sump pump work?

While a fish tank sump pump isn’t absolutely necessary, it’s undoubtedly an upgrade that offers many benefits. Utilizing an aquarium sump pump promotes healthier parameters for the water and even holds the equipment outside the tank so that all the room in it can be used by the fish. Typically, such a sump pump needs a piping system and at least one ball valve to guide the water from the overflow to the refugium. Other units are based on a simple intake that captures the water and guides it toward a check valve whenever the water level in the tank reaches a certain level. All this liquid then travels to the sump. There are several kinds of fish tank sump pumps, and so the design might vary from one model to the next.
