Great water shut off
Exactly as described. Not an issue but needs to be near sn outlet or use sn extension cord . Also if putting in a heater drain pan has to be on something insulating. Doesnt work directly on metal pan

Works like a charm! No more flooding!
Had a problem with the waste pipe backing up occasionally when the water filtration system was doing regen/backwash. Took a little bit to install, and get it right but that was more user error than anything. It would be nice if they offered a longer sensor cord as I wanted to use that for our hot water heater which was in another room, but can use an audio extension cable to extend the reach or splice the cord. Also, no way to mount the control box, but heavy-duty Velcro worked very well

Does NOT work. Alarm & shut off
This both an ALARM and SHUT OFF, direct electrical (battery is optional ) unit, does NOT work. There was substantial plumbing expense to link and attach plumbing (shut on & off) valve. Tested immediately. Sensors were easily activated when touched by hand (humidity). Quickly resolved by wearing gloves. Three (3) days later THIS product was RANDOMLY setting alarm in and shutting water valve Off. This again and again, despite following instructions to the letter RESETTING and opening water valve. The UNIT Repeatedly ALARMED & shut OFF water constantly

Only a 1/2" thru hole with 3/4" NPT
Product works fine. Smooth action, opens and closes in about 5 seconds. But the opening on ball portion is only about 1/2". Your water flow will be reduced.

Failed at 3 years
This valve is junk. Kept in a climate controlled area and cycled monthly. Valve stopped closing. The motor is too weak to move the valve.
