I have used many of these detector alarms and they work great at very small amounts of water(.2") depth and have a very loud alarm. Uses a 9volt battery (alkaline) and lasts about 10 months to a year
I used to want one of these behind the washing machine, it works perfectly well.
Was n't working at the reception! Fortune repair! Everything works perfectly now! modification of the piezo power supply with a test pin probably inside.
This water leak detector is excellent in sounding a very loud alarm in the presence of a small amount of water.Also has a light that illuminates at the same time the alarm sounds .Uses a 9 volt battery that will last a year or more.
Around 50 days long shipment, quality seems to be ok.
I get water in my basement every spring and when we get a ton of rain. Like when it rains for a whole week. This is a fail-safe alarm for when the sump pump stops working.
Very loud and sensitive! Exactly what I needed.
good
