Peggy - We have your book and have followed rather closely. The boat is in an area of tons of marine growth. We pumpout the tank with every use (not daily - end of trip/weekend or when full on extended cruises), hose/rinse the vent, use the KO and CP faithfully. We even flush the hose that runs from the thru-valve to the toilet once a month with fresh water and a little KO. There is NO odor except that "swamp smell" after being gone for a week. That lasts just 1 or 2 flushes, then gone. It does not permeate the boat. Hoses don't smell either. We do get that when the diesel starts too after being gone. That seems to be common with our creek. Everything has been great - except the last two weekends we seem to lose suction when pumping in order to flush. We have to pump a great deal - sometimes we get it back, sometimes not. Could critters be blocking anything? How can we fix it? Thanks in advance for your assistance.
