This Febco 767 FR PVB is advertised as being ok to leave it out in the cold. When I tried to purchase it at a local Colorado irrigation supply house, it wasn't available. I was told that it isn't made for serious cold weather like Colorado has, but more like what Florida has where it may drop a few degrees below freezing. A little misleading I would say. 

​I have personally changed out over 1,000 cracked ball valves in the last 20 years. Febco valves are the majority of the brand marketed in Colorado.Most of them have been specifically the Febco ball valve. The febco -valve product is really not at fault. Either are the Wilkins ball valves, the Watts ball valves or other ball valves. A person just needs to maintain their febco valve products. However, I would think that Febco and others would want to make a better cold weather valve. But they really don't because ,they make a lot of profit selling replacement valves. I have found contractors and local distributors to be of the same mind set. Greed & Corruption is what seems to be in the for front of their minds. They put profit before integrity.
