Troops........I spent the morning wandering around the harbor near here at
Charleston Oregon. I checked with about 20 fishermen and they all use the
Jabsco macerator pump 18590-0000 with the 1 1/2 intake and garden hose
outflow. After following our last lengthy discussion on macerator pumps,
I've come to the conclusion that the poor fishermen around here must eat a
different diet than all of us wealthy GMC owners do! ......Jim Davis on the

With the GMC everything is bigger and better. maybe a 3" intake will not
even be big enough!

Chuck....... As I said before, "This is the latest poop on macerator
pumps." .I'm willing to go along with what the fishermen have to say.
Defecation is defecation no matter how you look at it. If it works in a
boat, it ought to work in a GMC. I'm pretty sure I know where we can get
these 1 1/2 inlet pumps for under $100, so hold off and I'll let everyone
know in the next few days.....Jim Davis on the Oregon coast where it's

Hi Jim

Isn't this contrary to your post of March 30, indicating that H&F Boats
sell
the pump unit with the 3" inlet because the smaller inlet tends to clog
quite often? Maybe that's where the "fisherman's diet" comes into play!

Still macerator-less in North Idaho; had hoped to buy the 3" setup in
Bandon
this week, but not to be.

With all this talk and "The Latest Poop On Macerator Pumps" I have a dumb
question!

I think I understand what they do. They grind up all that "stuff"
in the holding tank so it fits though a garden hose. So where do you
dump using a garden hose? What's the point? Seems like it would be
faster to just let her rip using the big hose. I can see why they would be
very nice to have on a boat since you can't easily maneuver a boat to a
location
where gravity will allow a holding tank dump.

Could someone educate this GMC owner on the GMC reason for Macerator Pump?

Once you have installed this neat little system, you will surely agree
this is the best thing that ever happened to any RVer!. When dry camping
at the Scout Reservation we have been able to back up to the toilets and
pump up and into the toilets.

We have had this discussion on the Net before so I won't rehash it
all.... but I proved the value at Marion when several of us went to dump
at the same time and those with pumps were in and out in less time and
without having to wear gloves, rinse off or anything else.

Since my hose is permanently attached to the pump I only have to feed the
bitter (no pun intended) into the storage tube and I am off. My hose is
about 20' long and fits into a tube made of 1 1/2 schedule 40 that is
fitted along the frame on the driver's side.

Hi I belive our 73 pumpkin-Rose has the same Macerator system, But the
previous Lady owner said that it took longer to dump since the install of
the system. Is there different systems for this unit? This unit is in front
the rear bumper and the color is black and white, Thats the only thing I
know about it now.

Dave,
What is the inside diameter of your discharge hose??? And do you rinse after
each dump or just wait until you put it into storage at the end of a trip???

As an old hand at sailing and having spent many hours working on the head in
my sailboat let me tell you why the macerators work on boats. Setting in the
corner of the head is a brown paper bag, and all paper products are
deposited there. No exceptions. When I first got my boat I spent way too
much of my time working on that head but once adapting the "brown bag"
policy problems dropped to an occasional flush with fresh water. I assure
you that this policy has been carried over to the GMC.

P.S. If the "brown bag" policy is offensive to you then you can figure on an
inordinate amount of time spent working the head.

O.D. is about 1 1/8th or so, so I guess the I.D. is about an inch.

And do you

Since my hose is stored in its tube for travel It gets stowed before I
move the MH but I never rinse unless I drop the end of the hose into a
full sewer pipe. There is nothing to rinse. Remember my set up has the
hose clamped to the pump. Others I know have the pump exit to a quick
disconnect thru the body of the MH just aft of the battery compartment
but as a former boater I can't bear to put any holes in the "hull".

An additional comment. As most campgrounds insist on a good seal to
prevent sewer gas from escaping (and making the alledged hole in the
Ozone layer any larger- VBG), I bought a 3" threaded pipe cap and drilled
a 1 1/8th" hole in the center of the cap thru which I feed a couple of
inches of my hose.

Dave,
Let me get this right. You have a garden hose permanently connected
to your pump. The hose is stored in a PVC pipe running the length of
your coach. When you want to dump you just pull the hose out of the
storage pipe, put it in the hole and turn on the pump. A few minutes
later all the stuff is gone. You then might run clean water in to the
holding tank to rinse. When done, you turn the pump off and push the
garden hose back into the storage pipe.

Do you use a "brown paper bag" someone else mentioned for your
bathroom paper products? Or does the paper go down the drain and
out the garden hose too?

The more I hear about this, the more I think I like the idea.

Yes to the process you described above. As to a receptacle we do use
something like that but generally don't have a problem with paper. We use
a single ply paper and found if you try to minimize the water with each
flush you will end up with a huge wad at the bottom of the pipe. Some
additional suggestions.

I made a pressure cleaner for the tank out of 1/2" schedule 40 with a
cap glued on one end and a hose barb with a quick discnnect on the other
end. In the cap I drilled a 1/4" hole perpendicular to the tube. This
tube is then pushed down the opened valve in the toliet and the water
pressure is directed around the tank. I do this perhaps 3-4 times a year.

Also, with a mascerator pump, I have found it useful to lower the back of
the coach when dumping. When the tank is almost empty my wife will dump a
bucket of hot soapy water into the tank toilet effectively performs the
rinsing function.

I mounted my pump switch next to and above my city water inlet (driver's
side on a GM finished coach) This enables me to keep the switch out of
idle fingers and mounting it hgher up keeps it out of the way of the
water hose and power cord so no accidental starts. Easy access to the
back of the switch is thru the inspection port in the back of the hanging
locker(closet to you lubbers!)

At the extreme end of my storage tube I drilled a few 1/4" holes so any
residual water or rainwater will drip through and out of the pipe.

If your coach is stored for a long period, it is suggested to consider
running the pump once a month for a short burst to keep the impeller
lubricated. If any paper is in the impeller and dries out it gets really
hard. I haven't experienced this problem in the GMC but the pumps on the
boat used salt water to flush and it has a tendency to jam up a bit.

Any questions, let me know.

I just finsihed installing my new macerator pump 15 minutes before the
sky opened up. I can hardly wait to take a (^%&#) so that I can try it
out! The whole job only took 4 hours including BS time.

Also checked out the Alcoa's, they all had the same date on them, 0898,
so it looks like I'll have to clean them afterall.
