I have my sailboat docked at my house (I live on a canal). I am trying to get a pumpout system for my portapotty designed. My plan is to do the standard pumpout and vent line setup. This will be handy for when I go to marinas that have the tank pumped. But I also want to be able to pumpout the portapotty when docked at home. I was originally thinking about a Jabsco macerator pump that would suck the tank the same as the commercial pumpout does at the marina. I would run the outlet hose to a portable (on wheels) RV waste container, and then roll it to my sewer plug in the yard and dump into it. But the Jabsco does not have the lift needed to suck the waste out. I then found the Whale manual sanitation pump, which claims it can lift (suck) 15-feet. I need about 6-feet of suction capability. I hope you see where I am trying to go with this. Has anyone tried to setup a system like this for home use, or have any suggestions (Peggy?)? Thanks, PeteC
