The Basics of a Sump Pump Float Switch

Summary:  The sump pump float switch is responsible for activating the pump when the water level reaches the point where water needs to be relocated, and because of this, it is one of the most important parts of the sump pump.

For anyone who has a home prone to basement flooding or any type of water damage, a sump pump is an essential household tool to have. These neat gadgets are designed to lead accumulating water away from your home to a remote area where it can be relocated. Now, one of the most important parts of the sump pump is the sump pump float switch.

The float switch is basically responsible for activating the pump when the water level reaches the point where water needs to be relocated. One could definitely say that it plays one of the most pivotal roles in preventing water damage in homes. Therefore, it is always important to choose a sump pump for your home with a float switch that can easily be replaced, as you should keep in mind that the float switch is one of the earliest parts of the sump pump that may be broken.

There are different variations to the float switch. This is a primer to each of the types so that one may familiarize himself or herself with the differences and choose one that fits the house’s needs.

Probably the most expensive type of sump pump float switch available on the market is the diaphragm switch. These are mostly used by experts, and these can be found in submersible sump pumps that are completely submerged in water during use. The concavity of the diaphragm switch as the water level rises and affects pressure is what triggers it to activate the pipe, which then starts relocating water elsewhere.

The vertical action float is another type of float switch, which is the one most highly-recommended for middle class families who have no budget for the diaphragm switch because it is relatively more affordable. It is basically a ball that “floats” on top of the water. Therefore, as water level increases, the ball rises along with it and eventually activates the pump when the time is right.

Finally, the last kind of float switch is the tethered float. This is usually the type of switch that comes with the pedestal sump pump, which is mounted above the water (sump pit). This operates the same way a vertical action float does, except that movement here is less controlled. However, it is relatively to use this and a pedestal sump pump because one is less prone to electrical accidents.

The one important thing about the sump pump float switch is maintaining them and keeping them in tiptop condition. This means checking each one thoroughly at least once a year and making sure that there is no dirt accumulating in the edges, as this may cause the machine to be faulty, therefore increasing the chance of incurring further water damage.
