There are about three different types of sump pump float switches. Two of them are only slightly different; however, the third float switch is a little unique. But before you settle for one of these switches you must know what makes them different.
Now, here’s the good news. I am about to briefly differentiate all three types of float switches in the following paragraphs. So, if you really want to know more about it, then keep on reading this article till the end of this article to find out everything there is to know about it.
Types of Sump Pump Float Switches
1. Tethered Float Switch
A tethered float switch is one of the most commonly used float switches presently available in the market. This includes a switch connected to the motor through a wire. When the water in the sump pit rises, the float switch rises with it. At a certain water level, it activates the motor to start pumping the water out of the pit. The only downside to this switch is that it wears out quickly.
2. Vertical Action Float Switch
A vertical action float switch is one that is in the shape of a spherical ball floating on the surface of the water. This sphere rises with the water in the pit and activates the pump once the water reaches a certain level in the sump pit. It is more reliable than a tethered switch and less expensive than a diaphragm switch.
3. Diaphragm Floatless Switch
A diaphragm floatless switch is the one that operates on the water pressure theory. Unlike the other two switches, a diaphragm floatless switch stays put at the bottom of the pit. It is sensitive to water pressure and when the pressure reaches a certain level, the switch triggers the motor to start pumping.
How long does a sump pump float switch last?
On average, a sump pump float switch lasts for about ten years if you take good care of it and maintain it regularly. On the other hand, if you are not careful and don’t maintain it on a regular basis, then it will only last for a few months.
So, these were the three switches that you can use at your home. Just make sure that you know the characteristics of each of the float switches before settling on one. And that was all from my side. If you liked this article, don’t forget to share it with your friends!
