Leak Sensor Works!
I put the first leak sensor under the kitchen sink. It immediately alarmed.
Had a seep leak due to very slightly loose fitting. Tightened the fitting and dried the area. Put the leak sensor back. No leak since.
I now have 16 of these in my house. I feel much better about possible leaks now.
