Baomain10M 32ft Cable Float Switch Water Level Controller for Tank Pump

So far they're working great. I put one at the top of the tank to turn the well on and off to fill the tank and one most of the way down to turn the booster pump off if the water level gets low in the tank. Like I said they're working great. I appreciate they had a long enough cord to go all the way from the lower float, up to the top of the tank, and back down to the junction box.

Were good before, last 6 purchased failed almost immediately, one bad right out of the box

Bought this last year, lasted a year then leaked and stopped working.
