Jeez, just buy a new one.

That's probably not a bad idea.

I'm trying to figure out what it is so I can price it.
And how it works.

For example, what's the purpose of the four female fittings?

BTW, I found the Wilkins Zurn backflow checkvalve page:

But I haven't yet found the particular device to obtain price
and availability and instructions as to what those four fittings
are for.


There are some curious fittings on many of these backflow preventers.
I had a sprinkler guy install a new system and he said they are for
testing purposes and someday some code official might want to use
them for testing, but he'd never seen it done.

I would not get hung up on that aspect. If you're really concerned,
find what you think is a suitable replacement, regardless of the fancy
fittings, print out the datasheet
and take it to your local plumbing inspector and ask. That's the only
way you'll know for sure, regardless of what anyone here thinks.
