I've done all that Peggy suggests in her last post and it does make a difference. I changed out all my waste hoses this spring and did have a small effluent spill when the pump out hose was disconnected. Very little odor as previous winterizing pump out and rinse was very thorough but with some heat, I am sure those nasty little microbes would start multiplying and producing the soup Peggy spoke of. Almost all of the clean up was done with pail, sponge or rag and something like 409 cleaner. Got into all the nooks and crannies with a tooth brush and made the bilge area around the waste tank and every other accessible bilge area sparkle. Lots a work but, but not a single unpleasant odor present on "Suite Retreat".

If you call Gibson and try to find out if the hoses have been secured to stringers or other solid places, they may tell you that no clamps have been used. "B as in B, S as in S"!! I have several additional access ports in my aft head deck, aft head vanity floor , galley deck, storage area deck, and under the forward port bed. These waste lines are clamped to stringers and two people are necessary to remove and replace them. Again, it's not an easy job and the next time it must be done, maybe two hours at the most, instead of two full Saturdays. This is just part of removing offensive odors and a chore which must be done. We don't gotta like it, but it's necessary.
