So the weather here in E. Washington is unusually cold this week. The highs are single digits-- lows in the negatives. I just looked outside and realized that CRAP-- one of my hoses is still attached to the nozzle. I was able to put a hot washcloth around the nozzle and removed the hose very easily after about 30 seconds. There is ice in the hose where it connected, I can't tell how far it extends into the hose but the hose definitely isn't frozen solid from what I can tell.

I was/am concerned about the pipe obviously- there appears to be what I have learned is called an "anti siphon valve" installed on the nozzle. I am purely guessing this is what it is based on the description I have read about what happens when the hose is pressurized and the water is turned off (the water sprays back out from the nozzle and you are now soaking wet).

I was originally thinking before I researched this, that the valve was meant to prevent freezing pipes- by preventing water from sitting in the nozzle- not so???

I'm worried that I may already have a burst pipe and just don't know it. Any thoughts or advice??

eta: I also just saw that there is such a thing as a frostproof faucet. Is there a way to identify by looking at the faucet itself that I have one of these?
