HC8000T Electronic Sump Pump Float Switch – Built-In Alarms, Dry-Sensor Technology, Water Sensor Alarm, Ideal for All Sump Pumps – MADE IN USA

I have a small 110v garden hose discharge sump pump, this pump does not have a float, attached sensor per instructions to side of pump with sensor top about 2 “ above bottomof pump, and it works great

After my sump (sewage ejection) pump's float/switch failed, the pump still worked fine when plugged-in directly. For a while, I used a timer to turn the pump on, for one minute per day, which was not a great solution.This single-sensor product was perfect for my situation and enabled me to avoid having a plumber come to replace or repair anything.Now the pump comes on and goes off automatically again, whenever needed.My sump pit has a sealed metal "manhole"-type cover, probably because a couple of toilets and a shower and two sinks and a washing machine all drain into it.But there is a small hole in the concrete floor, near the manhole cover, which I noticed fills from below and overflows on the floor, whenever the sump hole gets overfull. The small hole in the floor is something like one inch (2.54 cm) in diameter, with a flared, funnel-like top section that has a somewhat larger diameter that the rest of the hole has.The included sensor unit fit perfectly in the small hole in the floor, next to my sump pit's sealed metal cover. It also stays near the top and doesn't slide all the way down into the hole, which is perfect. The sensing tip is a few inches below floor level. (And I guess I could get it farther down in there, if I really wanted to.)All I had to do was plug this unit into the wall, place the sensor in the top of the small hole, and plug the original pump's power cord into this unit. Done. I'm loving it.

Bought this and installed it over the weekend. Much nicer than a mechanical float switch. My sump runs a lot due to having a lot of ground water in my area, but the Rigid pump I use is a very solid pump. What always fails is the mechanical switch. So rather than waste $$$ replacing the whole unit, I started replacing just the float switch. Even so, based on the size of the sump well, the float switch wouldn't last or it would get hung up on an obstruction and stop functioning properly.This thing, on the other hand, is nice and compact. Zip tie it to the pipe, plug it in, and you won't believe how much space you just freed up. Using the manual calibration, I have it set for 15 seconds which is just before the pump starts sucking air. So now my pump runs fewer/longer cycles and does it reliably. We'll see how long it lasts. At 3x the cost of a simple float switch, I'm hoping to get at least 10 years out of it.

I love everything about the Zoeller M53 sump pump, except for the float switch design. The range of water level is just too low with the fixed switch design and runs the pump way more often than it should.I came across the HydroCheck line of products and experienced with the HC6000, HC8000 (not T), and this one (the timed version of the HC8000) and I can confidently say this is the PERFECT companion to the Zoeller M53 and the easiest/safest to use with that pump.With a few tweaks, this HC8000T allows you to essentially configure whichever water level you want the pump to kick on, but then rely on the Zoeller's float switch to turn off the unit without the pump sucking air, as it does with the HC8000.The trick with this unit is to IGNRORE the instructions that tell you to keep the float switch permanently raised on the pump itself, and instead, configure the timed amount to run just a few seconds longer after the pump's float switch turns the pump off itself. This gives you the perfect blend of an adjustable pump ON time and respect the pump's desire to turn itself off at its desired water level height. This eliminates my main issue with the HC8000 (non-T), which would run too long and the pump would suck air.However, by allowing the pump to turn itself off and not the HC8000T, the HC8000T will sound an audible alarm suggesting the pump stopped working. I thought this was going to be a huge flaw in my thinking, BUT the unit allows for individual alarms to be disabled! After the first alarm for the pump turning off by itself begins to sound, simply hold the "Smart Button" on the HC8000T for about 5 seconds to permanently disable that alarm.Configuring the HC8000T like this with any pump that has a non-adjustable float switch like the Zoeller M53 does solves pretty much all of my issues and gives you the perfect amount of adjustability, reliability, and safety. I couldn't be more happy with this setup.

Easy install and setup per instructions provided. The control unit is larger than expected, but, probably not intended for outdoor use with receptacle covers. I made due with an extension and covered it. Works great.
