[Public-List] Holding Tank Installation

[Peter Milley]

Thanks George,

Thee tank and vent lines are now installed and I have cloned your
installation.
The head on this Alberg 30 has a separate 1" diameter through hull to feed
water to the toilet. The discharge from the toilet goes up and over the
vented loop and then down through a 1.5 inch diameter gate valve through
hull.
I reasoned that I could tee into the vented loop on the down side high
enough up to permit good flow back to the tank and not the toilet. The
pumpout line would run off this tee to the deck fitting. With all through
hull closed it should pump out.. I do not plan to install a macerator.
Peter
