So now he's wondering "who the heck is Peggy?"
That would be me, Peggie Hall...moderator of the "Headmistress" forum, a forum devoted entirely to sanitation and odor issues, for the past 13 years. A link my signature below will take you to my book "Get Rid of Boat Odors"--a boat owner's Guide to marine sanitation systems and other sources of aggravation and odor.
Incredible that anyone could be here for two years without knowing that, or being aware of the zillions of discussions every year about Jabsco toilets and better alternatives that turn up all the time, not only in the Headmistress forum, but in just about every other forum too except maybe Don Guillett's Sail Trim forum. But you've finally "come in from the cold" and we welcome you!

You already got good advice...nothing I can add to it.
Snotter, you and Rick Dinon need to get together...he's already spent more than $800 in replacement pumps to keep his $100 Jabsco toilet working flawlessly...how many pump assemblies have YOU bought so far? Sounds like more than enough to pay for a PH II or PHC conversion
sbo.com PHII PHC LBA that you wouldn't have to replace for 20 years if you just keep it lubricated and rebuild it about every 5-6 years! The plastic won't crack if you remove and replace screws, and it'll "swallow" flushes that would choke a Jabsco to death!
But...it's your boat and your money to waste.:bang:
