It comes in different heights, but the actual valve is buried below the frost line. When you turn it off the water drains through a gravel bed you put in the bottom of the hole. No freeze. Valve costs around $60-100 at Tractor Supply, hardware stores, farm suppliers and on line. Just a thought. Boofer
Everyone back in Nebraska has those, they work great. Unless the connecting rod that goes down to the bottom is out of adjustment or the valve in the bottom goes bad and it doesn't quite turn all the way off, leaving the pipe with water in it above ground. Dad had one end up with about a 2' split in the pipe above ground. First time we turned it on, there was water sprayin' everywhere!
