I had a valve put in the main just as it comes through the wall. It's been been damn handy just for repairs & such. But the biggie is that if I remember, I turn off the hot water heater & shut off the water whenever I leave on a trip.
Wished I had some sort of an alarm on the meter down in the yard though. Was in the house for 2 weeks straight with covid a couple years ago & didn't notice a leak out there. $1500.
