Plumbing leaks keep repeating

[Mary Jay]

Hi guys,

Ive been getting plumbing leaks every 2-3 years in one of my rental , that create mold and it cost me each time 3k or 10 K to fix and get rid of the mold.

What do you think about installing a leak alarm so to speak?

Something like this may be?

Moen Flo Smart Water Monitor 3/4-in to 1-1/4-in Indoor/Outdoor Smart Water Leak Detector with Automatic Shut-off Valve in the Water Leak Detectors department at Lowes.com

Does anybody know any info on these? Do they work?
