[PSUBS-MAILIST] actuated valves?

[Alec Smyth via Personal_Submersibles]

That one even looks good! However, I think I've come up with a way to just
re-route the tubing that should work. So long as it works, a solution with
no remotely actuated valves at all wins KISS-wise, so I'll give that a try.

Thanks,

Alec
