And btw... Despite Dometic/SeaLand's claim to the contrary, 1 pint of water is not nearly enough to rinse waste out of the hoses and pump. At least 90% of VacuFlush problems are a result of using too little water.
Always leave the pedal down at least 3 full seconds following urine only...always add about half a bowl of water ahead of solid waste and leave the pedal down 7-10 seconds to rinse the system behind the flush.
I've written piece I call "VacuFlush 101" that explains how the system works (an amazing number of owners think they know, but don't) and how to prevent problems. If you'll send me a PM that includes your email address (no way to attach anything to a PM), I'll send it to you (and to anyone else who'd like to have it.).

Hi Peggy, any chance you can forward your book to radar09@me.com?
Thanks
UPDATE:
All, thank you for all the suggestions. I found a "small" worker that was able to get down into that floor hatch at the lower helm. We located the vent tube from the holding tank, it was not blocked. There was no filter installed, so I installed the Dometic ECO filter and dated the install. Almost immediately the foul smell disappeared.
The whole process took less that 20 mins to install and eliminated all the foul smells. I like simple solutions to boat issues...
Thanks, Peggy! It's about time someone points that out but I have been doing what you just wrote for years with absolutely no smell in the head.And btw...

I've been writing about it for years, as all those who've requested and received my article "VacuFlush 101" will attest. I'll be glad to send you (and anyone else who wants it) a copy to share with others who need it if you want to send me a PM that includes your email address (no way to attach anything to a PM).Thanks, Peggy!

USCG regs REQUIRE all waste tanks to be vented to the outside of the boat because the gasses generated in anaerobic conditions--sulfur dioxide, hydrogen sulfide (the stinky ones)--are toxic, and methane (which is odorless) is flammable.
