Freeze Proof Sillcock outdoor faucet

[NC1]

Hi, I have BMI Freeze Proof quarter turn sillcocks on my house. I had shut off 3 of them internally before the winter but left one on. I went outside and saw it was just letting water out of the faucet which was then freezing on the floor while the faucet was in the off position. What would be causing this? I have since turned the inside shutoff to that one off as well. It is less than a year old. Also, the anti siphon valve has a cover that gets tightenned on. Should this be loose or tight and is that the cause of the problem? Thanks in advance for the help.

If the body of the valve is not installed per the instructions or you left a hose on it, it has probably frozen and split. It must be installed with a downward slope to the main tube and it cannot have a hose left on, since either one can allow water to accumulate verses drain out, and then it can freeze and fail.

If it wasn't a 1/4-turn, another possibility would be a bad washer, but that's not typically an issue with a 1/4-turn valve.

Thanks for the reply. There wasn't a hose left on it and i think they come pre-sloped so maybe just a washer. Will look online if I can find any replacement parts. Any good online plumbing stores you recommend?

I would call them, and ask. http://www.bmicanada.com/contact.php

If it just needs a washer, you could probably take the parts to where you buy plumbing stuff locally and get a compatible washer.
