Saw this online Paul. Looks like they're in Bakersfield? If you scroll down to the bottom of the page, it looks like they make/have inlets designed for concrete walls?
[Link: builtinvacuum.com]Paul - Thank you! This is the kind of thing I was looking for. Not clear from the description if the inlet is compatible (or can be modified) to work with a powered "SuplerValve".
I left a message this morning to get some more information.
