Where does that go, Russ? Jim thinks it's on the face of the spigot to seal
on the valve stem. That looks possible, but I wouldn't say I saw anything
that looked soft on there - seemed like plastic to me, but it can't fit
insside the valve, so I guess it must seal on the face.
Is there a seal that's dropped out or something?
It was still working today.
For Jim: Yes, I have courier set up here - looks fine!
Dave.

I do not see the rubber sealing washer in those pictures.
