"stuff " flows downhill...always has,always will. I can't imagine trying to boost stuff uphill on a boat..I think a redesign is in order

I agree. With the lenght and uphill it will constantly take a lot of water pumped after each flush to keep the long hoses clean. Better a closer downhill tank even if it is smaller you would probably get more uses before having to pump out.

Any longish run ,I would have PVC pipe instead of hose and hose at the connections where needed

My forward head has a long run to the holding tank. Most of it is PVC. Unfortunately there are several 90s in the run. However it has not caused me any problems yet.

Even though PVC does have some disadvantages that Peggy pointed out, for a long run without a lot of drop, I'd still use it. It'll be easier to maintain a steady down-slope without any dips using rigid PVC instead of hose for the long part of the run. And that means less standing effluent in the lines, etc.

Vacuflush
For you Headmistress, I need to replace the pump bellows in my Vacuflush. I have all the duckbills and the bellows and o rings. I am vacillating between doing it myself, (then I'll know how to fix it again if need be) or having the yard genius at the marina do it. I'm a pretty fearless DIYer, but I'm a bit intimidated by this project. Any advice?
Also, apologies for hijacking the thread, but gosh for the original poster, it all sounds soooo complex. Anything on a boat should follow KISS. My dad was a HVAC guy and tried all kinds of simple solutions to things when they got too complex. They usually worked too!

If you can read then actually FOLLOW directions, it's an easy job. If you'd like for me to walk you through it one-on-one, send me a PM that includes your email address (unless you already have mine, in which case send me an email) and I'll be happy to help you.
