I have not had problems with bottom outlet holding tanks. I throughly wrinse
the tank several times after I pump it--and don't seem to have any sewage
staying in the hose at the bottom. The bottom outlet seems to get all of the
material--the top outlet by defination, because the pipe will be off the
floor, will leave material in the tank.

I have a bottom outlet holding tank with a standpipe. I used solid PCV
pipe to build a standpipe that puts the hose well above the level in the
holding tank...

I did the same, and also have a kind of 'p' trap just as the pipe comes out
of the tank, with a small loop of PCV pipe descending below the bottom level
of the tank. In this way when pumping out a vacuum is maintained until all
the stuff gets out of the tank. Just tapping off the tank w/o the 'P' would
allow the vacuum to break as the top edge of the outlet pipe is exposed.

I routed this to the top of the tank and placed my 'Y' valve on top. Then
used hosing to get to the pumpout fitting and macerator.
