Does anyone have a source for replacement valves (bonnets) for these manifolds?

    With the carbonate every where on the manifold, you might have to take the valves out clean and re-gasket them. May have to install new manifold.

    Yes, I'm trying to see if that can be avoided.

    Those bayonet expansion manifolds were popular for a time.

    Thanks, guys. An email to Giacomini last night and a response this morning from Legend. It's nice when things work the way they're supposed to.
