We have a SUPER old Champion Irrigation 1" Vacuum Breaker / Check Valve on our sprinkler system.
The whole thing is usually covered up and on a whim I decided to take a look and check everything. Well, it was leaking pretty bad... like a drip every second. The ground was completely saturated and there were some really stringy roots all around, so I'm guessing it's been doing that for a very long time.
Here's what it looks like:
I was very worried I was going to have to replace the whole thing, but my father-in-law suggested I might be able to just unscrew the top and replace the gaskets.
I unscrewed the top and the washers / gaskets (or what was left of them) were a mess. It's as though they had melted... black oozy gooey stuff.
I went to Ace Hardware, but since the gaskets were so far gone, they didn't know what to give me. They tried their best and I came home to replace the two washers with what they gave me, but it didn't work at all.
Luckily, I was able to find the model number of the unit and searched online. I found the parts and after a few calls I found a local place that had the washers in stock!
I came home and replaced everything. So far it seems like it's working great! I showed the guy at the store my pictures and he said, "I hope this works because changing out that whole thing is going to be a nightmare!!"
Here are a couple of pics of the top pulled off and the old gasket and new:
