This thread is very informative to say the least. I never gave it a second thought about winterizing the BWF lines (first time having a BWF). My back flow vacuum breaker is located under the bathroom vanity and happens to be the cheap black plastic one (it will be getting replaced). The water lines going to and from it are not PEX, they are that nylon braided hose. I really doubt this type of hose would actually break and/or split if some water was still in them and it froze??? right or wrong? Just a little worried, it's after midnight about 16 degree F and I ran out and looked and took pictures....
