Portable Macerators

[w schurman]

Other than installing a Norcold three way in my '78 Palm beach the most
useful modification was installing a Denny Allen macerator kit. Not only is
it easy and painless to dump but I like to use it when some SOB pulls along
side and goes through all the effort to get the three inch hose out hook it
up drain it out then struggle to clean it out etc. By then I'm long gone.

Makes sense. Thanks!

I just finished installing a macerator on my Royale. Each tank empties through a valve, then into a 4-way cross, then to a tee for the macerator, then
a single valve for the old 3" dump backup. The 4-way cross is fed from the black tank on the drivers side, the grey tank on the passenger side, the
macerator tee aft downstream, and a reducer to a 1" fresh water supply forward. The fresh water supply piping has a check valve ahead of the 4-way
cross connection. The macerator is switched with an exterior key switch. The switch, 1" macerator hose, and a 1-1/2" PVC electrical conduit for hose
storage are all gathered at the passenger side between the end of the coach and the bumper.

I haven't used it yet, but my plan is to first connect the fresh water hose with the hose bib off and pull the macerator hose out of its storage pipe
and run it over to the dump. Then open the black water tank valve and turn on the macerator. Next, open the grey water valve and dump. Next, turn on
the fresh water hose bib and flush the cross, tee, macerator, and 1" dump hose. Finally, turn off the hose bib, wait a minute or two and shut down the
macerator, store the macerator and fresh water hoses, close the valves, and drive off.

Bill,
Any chance you could post a few pics of your setup? That sounds interesting for us with two tanks, and no macerator system yet.
