Sump Pump Alarm, Indoor/Outdoor High Water Septic Tank Alarm with 110dB Loud Alarm and Large LED Indicator, 10ft Level Float Switch, Ideal for Septic Sump Pump Pond Water Tank

I'm in the uk. I bought this on the uk amazon site. Nowhere in the description is it's voltage stated. So I assumed it must be UK compliant, it's not, its 110v beware.

This float alarm works perfectly!! In my opinion. I adjusted the float slightly above the sewage ejector float on the opposite side of the tank, zip tied to the sewage ejection stand pipe. (To avoid any interference with be pump float). I unplugged the pump to allow higher water to ensure the float had free range. Plus I checked when the alarm would sound while the lid was off. I tested this a few times a day for several days and it works perfectly!! (I did this by unplugging the pump and allowing the water to build up) Once the alarm sounds, I plugged the pump back in and as soon as the water level dropped the alarm would stop. Perfect every time!! This Alarm is the best for its price range. No there’s no syncing with your phone but the alarm can be heard throughout a home. Plus the light is very bright!!

Easy replacement for our septic system. One piece unit that works as advertised, we shall see how it holds up long term

Gives me piece of mind about flooded basement, this alarm lets me know right away, I love this item

Works great

Good for sump pump_______if your pump quits water level will keep on raising but with this unit you will KNOW for sure that your pump has quit.
