What's to keep the screen from becoming clogged up, Lew? Tell me more
about this, 'cuz I'm having a hard time visualizing any screen in a
holding tank that wouldn't cause more problems than it solves.

The problem I see with any type of screen is, waste contains animals
fats...they're what clogs up internal holding senders...they build up
inside the tank--and I would assume on any screens--the same way fats
and grease can build up in sink drains. Are you onto something I need
to know about?

Btw...while I have at least a few people's attention...I may or may not
be MIA from this group for a week starting Weds...I'll be at the
Annapolis Sailboat Show. Fawcett's Boat Supply carries a lot of my
publisher's books (including mine, I hope!) and has given Seaworthy
Publications some space in one of their booths for "vendor support."
It's PRIME "real estate," too! In the big A-tent, right across the asile
from Raritan. I'll be there for the duration...so if any of you are
planning to come to the show, I hope you'll stop by the booth and say hi.
