Rowly - You should put a concrete pad around the windmill base. I've had several mills blow over in strong winds. Another possibility is to use three turn-in type anchors; one on each side and tether each to a leg brace. I prefer the concrete pad. Koenders will not warranty blow overs. Are you sure the hose is 1/2"? Koender's standard airline is 3/8". Did you or your supplier substitute different windmill hose?
