Hi Blair, Yes replacing hoses may be required, and WM will push you hose right away!. First I’d go to the pump-out on a weekday, suck everything you can, fill and do it again. If nobody is waiting maybe even a third time if you are new to the boat. Pour a couple gal. of water or run the hose into the toilet and really flush out the bottom of the tank. Sailing and banging the boat helps shake the old flakes out.
The vent is critical, and must be clean!!! Repeat: The vent is critical, and must be clean!!! Run water through the vent line so it’s being sucked in, while sucking out the tank. If you don’t hear it gurgling and sucking - your vent hose is plugged. Usually with old shit or maybe bugs. Maybe you can get a wire in to help, or replace that line first. The bugs that grow in the tank with-out air, really smell the worse! When you have a clean vented tank, at Noflex, mix like yeast. It’s the dried version of the “bugs” that you want in your tank. Kathleen flushes maybe a quart through the system after pump outs. Use your boat all year if possible - it might take a year or two, some hard sailing, and a lot of flushes before you see very few dried compacted flakes being sucked out. We bring a few 1/2 gal. milk jugs down to the head, and flush with fresh water. If you are day sailing and back to the dock, and it’s easy to top up you water tank, flush with the sprayer or a jug. Whenever you leave the boat, even an afternoon, especially for a week or more, flush with fresh water! Some folks have a pump-out service, and you should see how quick they can “service” your boat, likely on and off in under 3 min. - ouch! The nice thing about going to the pump-out - you are using your boat, which keeps many systems working, tips you off on the problems, and gives you lots of practice docking - a very good thing. Again, try to go weekday mornings, not Sunday afternoons when everyone is cranky and eager to get off the boat! Never on Labor Day!
