    Not reliable. I was surprised to find out it has a battery inside. I hoped replacing that would address the failed sensor but alas, it is more trash to throw out.

    replaced stuck float switch

      Comments about Wayne® Electronic Sump Pump Control & Alarm (AU5ES):

      I bought this to replace a stuck float switch in a black water tank under my basement. Long hair caught the float. The old float was seperate from the pump so I could just unplug the bad switch and plug this one in and piggyback the pump. Other reviews indicated that the red copper wire that comes with the switch corrodes away after years of use. I decided to connect it to a stainless steel rod as a sensor and it did not work. The stainless when in contact with the water did not detect water. A piece of lead was tried next but it did not activate the switch either. I then used an 18 inch piece of 1/4 inch copper tubing, I stuck it through the stopper at the top of the tank. A 14 gauge or larger ground wire made of copper would work just as well. This makes it adjustable and removable without disturbing the rest of the tank. The previous owner did not caulk the tank, he just coated all of the parts of the tank lid which could leak gasses with petrolium jelly so the tank lid was slippery but not stuck down. This kept the nasty smells inside but did not stop overflowing water. I also have a water alarm resting on the floor, and have had it for years.

      The battery jumper must be put back on for the battery backup to work.

      The end of unreliable floater switches

          Comments about Wayne® Electronic Sump Pump Control & Alarm (AU5ES):

          This small unit provides reliability to any sump pump unit taking away the floater switches unreliability (mine got stuck twice between the pump and its self-containing well) adding the advantage of sucking out water when it reaches the desired pre-set level up-to-the-last-drop. Easy to install, it gives peace of mind to the homeownwer who has to deal with a sump pump.
