Moen now sells an all-in-one security system for your home water.  At an affordable cost of approximately $500, you can avoid water damage and detect and stop leaks. From your toilet, shower or faucet, to the pipes in your foundation and behind your walls, the smart water valve monitors all of them so there's no surprises on your water bill or catastrophes when you come home from vacation.  There may be other brands/systems available, but we ran across this one and thought our customers would be interested to know the technology is there for purchase.
