Yeah, I prefer curbstops I hate gate, globes or ball valves below18". This will make some people groan but when it came time to winterizing we always "puff" the doublechks and what I did was open #1 testcock and then puff air through #2. What I don't understand is a shut off valve right before the dblchk?
