I'm not sure how long the 9v battery lasts (years?) but you can place it next to an appliance and forget about it until there's a leak. Worked for me when the hot water heater started leaking.

1/17/24This alarm went off when water was leaking in my basement last week. I had forgotten that I had this setting on the floor. There was this beeping noise in the basement so I investigated. To my surprise the last time I changed the battery was 11/17. I thought no way, but the markings on the battery was the same. (Battery Duracell Procell Use Before MAR 2019) I recommend this combination for anyone who needs to know if there is water somewhere it is not welcome. I just realized this has the ability to remote sense water.(contacts on the bottom detach and wire inside can be extended so it can be placed next to a hot water heater in the drip pan, or A/C half way up the drain pan to let you know before it overflows. Put the alarm box next to the crawl space door and mark it A/C. That also helps to remind you to check the battery once in a while at least every 5 years)

Love that alarm only requires a 9v battery and no installation…I hate going to the basement but hate surprises even more. I have a mature water heater, and my plumber suggested the alarm to help but some time for replacing the heater.

I live in a 4plex. I already have one of these next to my upstairs water heater. After my neighbor had a dishwasher with a slow leak ( lots of damage) I bought another one for mine. Cheap insurance.

My plumber told me about these watchdog water alarms. Very inexpensive. I had a hot water tank leak. I got a new hot water tank put in and I purchased one of these watchdog water alarms. 2 days after I got the water tank put in the alarm went off! I purchased them for under all my sinks. It really saved me from having a mess. My new hot water tank was leaking!
