Sure you can pick up a shut off valve from the big box store for a few bucks. But they aren’t full flow meaning the water flow is restricted and it will take forever to water the yard or wash the driveway.
Plus your kids can’t turn on or off those cheap ones since the lever is so small. Then after a few uses, the lever falls off.
And don’t even bother with the cheap plastic or aluminum full flows. Drop them once on concrete and they break.
