I've got the portable flo-jet version. Before full-timing used it continuously at our sticks-and-bricks to connect to our septic system. I fitted it out with connections to allow use of 1-1/2 "flat" hose. Flat hose rolls easily and stows compactly. Flat hose and associated fittings are/is generally available at farm supply outfits. I now mostly stinky-slinky but still keep the macerator for long distances and up-hills.
Had to replace impeller once, easy to do since it used standard JABSCO marine macerator parts. I think the impeller kit was about $8 and took about 15 minutes.
To make electrical hook-up easy, i replaced the cigar-lighter electrical plug on the unit with a 12V, 20A trolling motor plug. I then installed a 20A 12V receptacle with an adjacent switch in my basement panel. I can hook the macerator up, plug it into the basement receptacle, just pull the drain valve lever and flip the adjacent switch.
By the way, the Flojet has a water hose connection right on the unit for flushing it, and the flat hose sure flushes cleaner than 20' of corrugated slinky.
