I use the
watercop system to stop plumbing leaks. Its expensive, but I like all the functionality. It's nice to have a switch at the top of the basement stairs to turn off all water, It also can connect to other security or control systems. I got mine after moving the laundry to the second floor and finishing the basement. The convincing thing was when my daughter propped a glass in the frig water dispenser and forgot it, then went to school for 8 hrs. Around the same time, I had a friend have a PRV fail and have 125 psi break a plastic part in the water softner and ruin his basement.
