foul odor when flushing
During our first camp with this new TT, I added the chemicals from the dealer when we arrived at the campground. We had no odor issues. I dumped and thoroughly backflushed before we left the campground. I did not add anything to the tank afterwards.
However, on our second trip, I did just as before and added the black tank chemical right when we arrived. On day 2 we noticed an odor when we flushed and the flap was open. It got worse and worse each day. We made sure we used plenty of water when flushing. The black tank dump valves were closed the whole time. We cleaned the toilet bowl thoroughly to make sure that wasn't the problem. The flapper holds water just fine. The smell only occurs when flushing.
The only other variable I can think of that was different between the two trips is on trip #1 we left the gray and black dump valves closed the whole time, then dumped each at the end of the trip, but on trip #2, I left the gray dump valve open (and black valve closed) til the next to last day so it could fill and be used to rinse my dump hose after I dumped the black tank.
Any thoughts/advice are welcome.
