Leaking outdoor faucet (help identifying type)
My wife and I moved into a new house a few months ago (Northern Virginia area) and I went to turn on the outdoor spigots yesterday and found they were leaking. They seem to be frost-free antisyphon type sillcocks, however, they have a strange plastic collar on the outside that one slides up during the winter to ensure adequate drainage (I presume).
Over the course of (perhaps multiple) winters, the o-rings that seal this collar have deteriorated and in fact crumbled out (as can be seen in the photo below).
My first question is: 1) What type of spigot is this? I have never seen one with this type of drainage mechanism before.
2) Is repairing it just a matter of replacing the O-ring?
Perhaps not legible on the photo is the brand of the sillcock -- Legend (best I can tell, it's a Moen subsidiary???)
Any advice would be appreciated, thanks to all in advance for your time.
