Best Sump Pump Float Switch Reviews Of 2024

A sump pump is an electromechanical device that pumps water out from a sump basin usually constructed in the basement to let the flood water accumulate through the internal drainage system. A Sump Pump is mainly designed with three main components, a motor, impeller, and float switch. A float switch plays the most important role in a sump pump because it activates the pump to drain the water out when the level gets too high.

Amazon has a wide collection of float switches at very affordable prices. Take a look at some of the best sump pump float switches and controllers and don’t forget to read up on how to install a new float switch.

PumpSpy Sump Pump Tethered Float Switch

If you are looking for the simplest float switch and easiest to install, there is no need to look any further. This is the float switch I use now, and will continue to use anytime I need to replace it or if we buy a new house.

This float switch is compatible with any and every main sump pump you can buy and even comes with the hose clamp to make installation incredibly easy. All you need to do is plug this switch into your outlet and then plug your main pump into the back of the plug and now your pump will activate when the switch sends electricity through it’s plug. The relay inside the plug will only allow power to flow through when the float bulb is tilted so that the cord is facing down, anytime the end that the cord pokes out of is facing upwards it will shut the pump off. So, the only other thing to do to install this is use the supplied hose clamp to attach the cord down into the pipes in your sump basin. When the water level rises it will carry the bulb with it, which will position the cord downwards and trigger your pump to kick on. Then after your pump has drained water from the sump pit the bulb will again be lower than the “tether point” and it will shut the pump back off to wait for the next time your water level rises high enough for the pump to cycle again.

Features

  • This float switch is rated for up to 15 amps which should be way more than enough for almost all the sump pumps available for residential purposes.
  • Can be customized to your liking, if you want your pump to cycle frequently but for a short time period leave less cord after the tether point. If you have a larger pit or want the water to reach a higher level (and have the space) you can allow more cord after the tether point.
  • A 10 foot cord means you have extra length to use in case you need to reach an outlet that is far away
  • Gold plated electrical contacts that can resisto pitting and wearing
  • It’s simple operation means there are not many parts that could malfunction causing damage to your basement

Pros and Cons

PROS

  • Compatible with ALL main sump pumps
  • Comes with the hose clamp needed to tether this on to your existing plumbing
  • Extremely easy to install

CONS

  • Make sure nothing in the basin will obstruct this from floating upwards with the water level
  • You may need to “fine tune” the ideal water level height by adjusting how much of the cord is tethered to the float bulb
