Re: vacuflush head
Just starting to get a bit of experience on vac syms. as my friend just got an older SEA RAY with that system. Took some figuring out, sym. uses very little water. Velocity of flush is supposed to break down waste headed to the vacuum tank, as vac pump creates more vacume in tank, it also pumps waste to the holding tank. Holding tank is then pumped out or the macerator pumps dumps overboard. Looks good on paper but could be a nightmare. Friend is currently replacing macerator pump, I dont intend to be around as the connections are at the lowest part of the tank and he is not quite sure of the tank lines are empty ( probably not. ). I think BACKWATER DAWG is giving good advice by leaving the system as is.
Must also add that I have TOO much experience on aircraft waste systems. 767 came out with the vac flush system and could be a nightmare. About the same time the 757 came out with the conventional individual lav waste tanks for each lav. Very little problems with the conventioal system and is why I recommend keeping things simple. Mind boggling the things people would put down the toilet. Dont remember the reasoning but people coming from overseas would discard their passports and visa down the toilet on international flights. Had something to do with them being better off undocumented on arrival. Maby I should not have mentioned it as I forget the details. regards FRED
