PumpSpySump Pump Tethered Universal Float Switch Replacement with Piggyback Plug for Sewage, Reliable Water Level Performance - 10 foot cord

I had a sump pump that wouldn't shut off when the sump level got too low. This switch was the perfect solution.

If you want a “set and forget” sump or sewer ejector pump, one of the best things you can do is NOT buy a pump with a built-in vertical float switch. Cast iron pumps can last up to two decades; vertical float switches can fail in a year or two. If the vertical switch is built into the pump, you may need to trash a $400 pump when a $30 float switch fails.A better approach is to use an external piggyback type float switch. That way if the float switch fails, you can easily and inexpensively replace only the float switch and keep using the pump.The best external float switch type for most residential sump and/or sewer ejector pumps is a tethered piggyback type like this one from PumpSpy. Best in terms of simplicity and long term reliability. There are reports that tethered float switches can last for decades. We haven’t been using them for anywhere near that long, but the switch mechanisms are designed for millions of activations and there isn’t much to go wrong with this float switch design.PumpSpy’s tethered float switch is about half the cost of a similar design from Zoeller, and a third the cost of a similar design from Sludge Boss/Pit Alarm. We’ve been using this float switch for a while and find it sufficiently buoyant and completely reliable.The only cons?The PumpSpy tethered float switch has a molded seam on its exterior that potentially could catch on TP or other suspended solids in a sewer ejector basin. The Zoeller and Sludge Boss tethered floats are both completely smooth on the exterior.The PumpSpy tethered float also is smaller than the Zoeller model and a lot smaller than the Sludge Boss model so its maximum buoyancy will be less. Smaller size is a plus for smaller sump pits, but the thicker the suspended solids in a sewer pit the greater the need for higher buoyancy. All in all, for us the PumpSpy float has always had sufficient buoyancy.

Very simple, standard float valve that does exactly what it is supposed to do. Not flashy, but it gets the job done.

Easy to install, reliable and works as designed. But I had to install it somewhat lower in the well than expected for it to operate. Don't know why.

Excelente

I initially installed it incorrectly. However, once I fixed it, it worked fine.

Seems to work

I reviewed many other products before selecting this. It's been a month now since I installed and so far I am happy with the performance.
