More about my black tank odor issue
--odor is only present outside the RV and when down wind of underside of RV which here is most days
--in back flushing the tank it looks like a small stream of water oozes from the top side of the tank and down the side of the tank above the back flush inlet hose connection.
--inlet hose and its connection into the side of the tank stays dry
--water that oozes down the side of the tank doesn't seem to give off a smell
--could the mechanism that is used to back flush the tank have caused a leak to develop in the top of the tank if too much water pressure was used to back flush the tank ? (BTW I use a water pressure limit value for max of 45 PSI)

I wonder if somehow a crack developed in the top of the tank via the back flush mechanism if that makes any sense......I am new to this RV stuff so please don't laugh too hard at that comment

Thanks for any other suggestions about this issue..........
