Hi again Ricky! The VacuFlush VHT has a combination vacuum tank/holding tank--hence the VHT designation...the WORST idea ever! I don't think it's still in production. Count your blessings you have a "normal" VacuFlush.
There's no way the screw-in attachment into the deck
pumpout fitting had anything to do with extra water...pumpout connections have to be air tight to work
I've written a piece I call "VacuFlush 101" that explains how the system works and how much water it really needs to keep it working trouble free that I'll be glad to send you along with a copy of the VFlush trouble-shooting guide if you'll send me a PM (private message) that includes your email
address (no way to attach anything here or to a PM).
PuraSan EX is an excellent onboard sewage treatment system (US Coast Guard certified Type I MSD) that's legal
to use in all waters that are NOT designated "No Discharge Zones" Unless you're in NDZ waters, you'll love using it because eliminates the need to use your holding tank
.The EPA publishes a list of those by state EPA NDZ list
They keep it updated. You'll find Raritan's "promo sheet for it here Raritan PuraSan Promo Sheet
and the "Installation, Operation and Maintenance
Instructions" (aka "owners manual") here Raritan PuraSan EX owners manual
And finally for now...at the risk of appearing to be trying to sell you something, I think you'll find my book (see link in my signature below..just click on the title) useful in learning
how operate and maintain your toilets, tank and sanitation plumbing
. Its title (my publisher's idea) is a bit misleading...'cuz although it does deal with every source of odor
on a boat
and how to cure, or better yet PREVENT 'em, it's actually a comprehensive "marine toilets and sanitation systems 101" manual that explains the laws, describes all the types of systems and how they work
, and will help you learn how to operate and maintain your system to prevent 99% of problems instead of having to cure 'em. 'Cuz you get to do any preventive maintenance
on your terms when it's convenient...the need to cure a problem never happens when it is! And I'm always glad to help solve problems and answer questions.
Oh...btw...It would be helpful to other members here if you'd provide a little more information about yourself--your location (at least your state or country if not US) and your boat (1993 44'Ocean Alexander). I also recommend that you check out the sister site to cruisersforum.com--trawlerforum.com That name is a little misleading too 'cuz the members aren't just trawler
owners, many of them own large motor
yachts. You can learn a lot from them!
P.s I'm still convinced that your excess water is due to a failed water valve.
