Liberty Pumps ALM-P1 Indoor High Liquid Level Alarm with Probe Sensor

When I received this high water sensor it was immediately obvious that it was US made. It was NOT made in China! Super well built. The version I received looked a bit different from the picture, but it was better than the one pictured. It's solid. They even throw in an extra sensor plug so you can make up your own length of cable and still plug it into the sensor. It's plenty loud, and there are red LEDs around the sensor that flash during an alarm, so you get audible and visible alarming. The sensor itself is caged inside a tube that prevents heavy floaties from tangling with the float. They really thought everything through. American made. Love it.

Coolest thing I ever bought! snaps over sump PVC pipe and set it at the height you want it. Have backup generator so love that this plugs in to 110 volt outlet and don't have to deal with batteries to be changed once/year

This was a great purchase. It has already been worthwhile by alarming twice when the sump pump didn't work properly. It has met my highest expectations.

Attached easily. Very accurate and dependable.

Good piece of mind. Product is well made. I believe it's better then the float type but I couldn't find any pros and cons of this probe versus the float system. So hopefully I never hear it go off, but at least I have a warning now. Cheap security.
