Quartermaster Brass Anti Siphon Frost Free PEX Connection Sillcock.

Beware using this as retro fit. It takes a bigger hole then other valves. Include extra time to drill out the hole for the big hex flats at the end. Why would the maker sell a pex barb AND include the a 1/2" NPT. It just makes the end so big. I had two to do in brick. Good thing I had a diamond hole saw that I use for putting faucets in stone to bore the small original hole out. Had one leaker. I hate it when a well engineered product is assembled poorly. Bad factory o ring installation

Stainless, no plastic, will never need replacing.

Works well. I like the 1/4 turn feature. PEX end makes it easy to hook up to my plumbing. There were a couple things that I didn't like. I had this item in my wish list for awhile. I noticed the price dropped a fairly decent amount, and decided to buy 3 of them. I placed the order, and unfortunately my order was cancelled by the seller, and the price went back up higher. I would have liked to have gotten the price cheaper. I was only willing to pay for one at that time. The pipe also needs a pretty large drill bit. I would recommend at least 1 1/14'.

Perfect

I did it!

As soon as we turned it on it started leaking from the quarter turn feature inside the handle.
