johntk, to answer your question, no, you definitly should not try that. The liquid waste will accumulate in the flex line and the vaccum generator, and never make its way up to the black tank. I know it is noisy,learn to embrace the sound, for it will tell you when some thing is amiss. This may sound gross, but consider a sanitary system that you can live with to NOT put any paper of any brand or type thru the system. Mostly unspoken system, but someone has to say it . Read my post in fleetwood owners area flushed the vaccuflush, it will enlighten you as to what I have been through, and done to make it easier to live with. The BEST advise I can give you is to run water after flush, holding petal down for a count of 5 to 10 seconds before lifting foot fast to let clamshell SLAM closed. Goes against everything that everyone has always been taught to go easy, but it needs to slam shut to seal correctly. The extra water will help keep duckbills,pump,and inside of flex hoses cleaner,therefore hopefully less maintainance. Oh, and would also be a good idea to carry toilet seals,fill valve, o rings ....just in case
. I have an account with northeast marine sanitation, great guys, very helpfull. hope this helps.
