Chuck-
>screw on MALE connections and caps at each end...

What did you use for these hose end fittings, and the female ones that will
mate with them?
Dick Guthart

Hi Rich! This is Chuck from Lompoc, CA. We have a 78 Eleganza. The
macerator is installed on the Drivers side for the obvious reason of the
exhaust system on the passenger side. The pump is rubber mounted and
the dispensing end has a hose that runs to the end of the coach along
the rear of the frame and on the inside and then a "T" with a piece of
hose pipe going to each side following the under frame at the rear of
the coach with screw on MALE connections ands caps at each end. This
allows you ease at either side of the GMC for use. Beneath the coach
the main drain was cut into with an elbow installed this keeps water in
the main elbow and does not allow odors to continue out of the system.
Also it is a moveable connection so as not to be too ridgind. It is
placed just prior to the main dump piece that can be raised or lowered.
I have found the macerator to ge completely reliable over all these
years and have never had to use the main drain accept by choice in a
camp site where it is easier to just install it in the main drain owhen
we will be parked for more than a day or so. Then you just go out and
pull the gate valve lever near the genset. I like it this way and have
not caused any real changes to the GMC other than cutting into the pipes
whichj is not evident unless you crawl beneathe the coach. Also the
starter switch was mounted on the left hand side (drivers) side at the
rear into the fiberglass cap and just beneathe the bumber area out of
sight. Works for Us. Chuck PS You might want to get a rebuild kit for
the macerator as the thing oveer time might start to leak a bit. I have
rebuilt mine once in 10 years.
