Tethered float switch problems.

The float switches for sump and sewage pumps are known to fail sometimes all too frequently. Diaphragm switches are generally the. Other pumps use floats that are on arms which will raise and lower with the water level. When the float rises it is supposed to trigger a switch that tells your pump to turn on.

It hangs from the pump and sits on top of the water. Most systems need to be adjusted at least one time to get the float at the perfect level. In order to test a tether switch simply grab hold of the float and position it so the wire side is facing down. A tethered float is one that is attached to the pump using a tethering device.

Different types of sump pumps use different types of floats. A tethered float is used primarily for pedestal pumps. A pedestal pump will generally have a bulb style float attached to a metal rod which activates the motor s switch. The creator of this video believes the failures are due to the.

The float rises with the rising water level and throws a switch that kicks the pump on. As water level decreases to a certain level the switch then turns the pump off. If the float switch is still not at the right level detach the power and readjust. Once the water level drops the float drops loosening the tether releasing the switch and shutting off the pump.

The float rises with the water and turns on. Once the cover is off and located and you ve identified the switch a tether switch is easy to test.
