somehow my holding tank has emptied itself and was collecting in the rear
bilge compartment. we thought originally that it was a slow "oil" leak
from just having tke oil changed, but after flushing out the bilge it came
back....
planning that it was getting time to pump out the holding tank which had
been 3/4 full was now less than 1/4 full what could make this happen. it's
installed in a 1999 2600 martinique with 175 hours and not a lot of use to
the toilet system...

could there be a hole or crack in the tank? or maybe a paper clog? what do
you suggest?
