Looking for input on Water Leak Detectors

[Esteban Valverde]

Hello, I am currently rehabbing a house and eventually doing a short term rental with the house.  The issue is that we had a worker leave an open faucet overnight and now we are concerned about possible issues with high water bills and future leaks.  I have been looking at water leak detectors and wanted to ask if anyone else has experienced this and what recommendations they have on detectors. 

Thanks,

Esteban Valverde
