Instead of a post in the general forum, I figured I would ask the brain trust of you handymen.
Our house was built 30 years ago. The sillcocks are original to the house. As that they are in a brick facade house, I would have to chisel out mortar, and fight with that to replace them, entirely. See the bottom photo. The seal on the end shuts off the water when we are done using it, and it works fine.
This is the problem as I see it. The faucet shuts off just fine if we are done, but while in use it leaks from the weep hole in the shaft of the faucet. I shut off the water, and removed the entire shaft, repacked the packing gland, and cleaned out the vacuum breaker.
I think our issue is the little chewed up washer that is between the square piece, and the end piece. I can't find anyway to to get the little flat washer replaced, and it looks like there is another seal behind the square part.
This is the vacuum breaker.
I have no idea what brand it is, or I would just buy an entire sillcock and just replace the guts.
So any ideas on how it can be replaced?
