I just bought two quiet flush Jabsco 37245-1092 toilets, these include a waste macerator, bowl discharge pump and sea strainer ($453.17 each). Furthermore a Moeller 50 gallon waste tank for 2 toilet systems ($454.95) with 8 in/outlets and vents. I'm still not sure where to put the waste tank, but I'm confident I'll find a decent place, keep you all posted! For now, thnx for all the useful help! ps If anyone would like to have the old parts, just let me know, in exchange of a tray Budweiser its all yours!!
