Hi Bev, A couple of things from my experience of a smelly tank after launch this year: - If the holding tank is smelling, make sure your holding tank vent is working. Anaerobic bacteria cause the particularly noxious smells; they are replaced with aerobic, less smelly, bacteria if there is sufficient oxygen supply. My solar powered fan on the fore hatch broke early this season and the tank started smelling. Replacing that vent fan seemed to cause enough ventilation of the tank (under the v-berth) to solve the issue, so any minute air circulation will help (the vent wasn't blocked). Similarly, getting rid of mud from a wasp nest in the vent hull outlet solved an issue a couple of years back. You are going to have some salt water / waste in the tank regardless of ending the flush with fresh water. Vinegar dissolves salt residue in the hoses / tank - flushing a few gallons of white wine vinegar through the head and then a nice upwind slog into steep chop should clear any build-up out at the next pump out. - if the head is smelling, the fresh water flush will prevent decomposition in the bowl, but make sure that the valves on the head pump / outlet aren't letting anything to flow back from the outlet hose. The joker valve is the usual suspect, but if you're having to pump a lot to prime the pump to get flush water flowing, or to empty the bowl you may want to check the other pump valves too (advice from the list would be to replace the pump assembly completely).
Hope this helps. Tim Mojito C&C 35-3 Branford, CT On Tue, Sep 2, 2014 at 10:11 PM, Bev Parslow via CnC-List < cnc-list@cnc-list.com> wrote: > Four years ago I replaced all the hoses for the 29-2.
