Totally surprised and confused when I finally got the switch repaired so I can run the Macerator, only to discover that it pumps sewage out the hose that comes out at the bumper, not through the sewage hose. Is this the way it's supposed to work? Why in the world doesn't the output of the Macerator go down the sewage hose and thereby into the dump station?

Jay, what would be the point of having a macerator if someone were just planning on using the big hose anyway? The smaller hose adds ease of use and storage, dump location flexibility (you can use a house sewer system cleanout, etc) and distance/height pumping ability.

Hopefully the surprise didn't end up on your shoes. Wink

Jay, it is not pumping out the 3 inch drain, it is gravity flowing. You can't have that open with maserator running. If the pump is not pumping thru the little hose, but is running then you have a broken impeller. It will work with one blade off, slow, but if two in succession are broken then it won't pump. The one I repaired last week had a cracked impeller and it slipped on the motor shaft, no pumping. These are simple but if it has been sitting, dry, then the impeller may be busted. Jim K has the kits about as cheap, or cheaper, than anyone else.
This can be a frustrating experience. Ask me how I know.

That ain't a problem, that's a feature! No more stinky slinky for those of us lucky enough to have a macerator. I think mine was the best use of the previous owner's money ever!

I was told at the last meeting of the great minds of the cruisers of the pacific coast that it was best not to put a stable

M pump right off the tank but to put it on the end of the original pipe by the bumper and attach it and store it as needed.

like this one from campers world:

http://www.campingworld.com/shopping/item/flojet-rv-waste-pump-kit/26125

attach it when you need it, and then if you are stable at a place it will not load up setting. if the pump goes out or

gets stuck you can fix it easy. This is what the person told me was better than putting one in that is hard to remove.

It makes sense to me. for if you set a week at one spot you would use the big tube all the time to the sewer line.

when you need the little hose pull out the kit attach it and bingo you have the super pooper going. mickey

is this a good idea to those in the know. whats the poop on this poop. 77 palm beach. anaheim ca.

And how is a non-installed macerator any easier than a "slinky" 3 inch hose?

You have to take it out and connect it. Then connect the hose to it and hook up power. When done, you have to clean it all out, disconnect and store it all.

I had less steps with the OEM set up!

With my macerator on my two waste tank Birch it is very easy and quick to dump.

I pull out a hose from a pipe under the rear bumper, take the cap off and stick it in the dump site. I open the gate valve for the black tank and turn on the pump. when it is empty (less than a minute), I close the black tank valve and open the grey... a little over a minute later I turn off the pump, put the cap on the hose and slide it back into the pipe under the rear bumper.

-- done --

You'd still be setting up to run the "portable" macerator.

(Having both black and grey tanks really works well with a macerator! You rinse out the hose with soapy water!)

The only advantage of the linked system over a 3 inch dump, is it can dump through a "garden" hose... up-hill and for a distance.

But I can do that with my set up, so I can not see NOT installing it if you have it. Rolling Eyes

My PO installed my macerator behind a plumbing T connection, which is just behind the blade valve, so I can hook up a 3" stinky slinky (this also provides a way to empty the tank if the macerator ever fails, of course). Even with the ability to use a 3" pipe, and even though I have a stinky slinky in my overhead pod, I really can't imagine it would be worth the hassle to ever use it. If I'm parked long-term and fully connected, I'd just stick the itty bitty little macerator hose into the sewer inlet (with one of the adapters to seal it off, if necessary), and run the macerator for a minute every few days. I think long-term your black water tank just works better if you let the water level ebb and flow, rather than counting on gravity to drain every new input (I'll stop now so I don't get too graphic, but think about it...).

And besides, draining the gray water tank through the macerator when you're ready to go leaves it a WHOLE lot cleaner and easier to deal with than any used stinky slinky.

thank you and mark for your designs.

I was told that it does plug up or burn out once a year or so, this is a major let down in time

and getting the fixed pump fixed again. How many times has fellow gmc.ers had to fix pumps

that are blade broken stuck or just burn out? The one bellow has a fresh water clean out that from a hose you back fill it

till it is clean as a whistle. i do not have a gray tank, but am interested in putting one i some where on my palm beach 1977.

The one below with a glass attachment can be seen clean and fully clean out the black tank.

Having both would be also available so if one brakes the other would also be available. But that is 300 dollars more for the extra

one. I was told if you park a long time that you keep the gate closed but the 3 inch is put to the dump at all times while parked.

then once a week you open the gate and empty. So this can be good to have both big gate and marcerator.

How long does the fix pump work without having to be replaced or have broken blades or subs that revolve and they

burn out easy as well, the motors, thank you if you have any other ideas let me know please. mickey anaheim ca, 77 palm beach.

The storage in a plastic pipe along the under carriage looks good for storage. like sword sliding into it. You can have a 20 foot hose

storage under the frame. from around the onan area. sani-con looks good as well. IT looks as if one could put a supper

blade fan that would cut anything in the pipe area exiting the black tank, why not make it cut regular paper and any thing

that would be put in there. some real cutting blades high powered and sharp 3 inches in diameter. This would be major up grade.

A 3" blade would take a lot more torque, require a bigger motor, weigh more, clog and break more often. Other than that it might work, still wouldn't be an upgrade. Wink

If you want a low tech, easily replaceable, non-electric "macerator", look at the Sewer Solution products.

MM,

I have never had any sort of problem with my PO installed Macerator. We have owned the coach for five years now and use it an average of 30 - 40 days per year (not all at once). The closest thing to a problem I have had with it is it will trip the self resetting circuit breaker once in a while, but only when it is really hot outside. I still have the capability of dumping with the 3" hose but have never had to use it.

Keep it wet and you should not have a problem with impeller. You let it sit dry or try to run it dry, it will break an impeller blade. Don,t worry about it, use it like it should be used. I have been guilty of running one too long to get last bit of liquid out of tank. Don,t do that.

Good advice. You should also add, "don't let it freeze". Very Happy

I second Carl's "don't let it freeze". I would absolutely not consider a
coach without a macerator. My pump is easily replaceable, and 3 inch
bypass if it fails on the road. I did leave it full of clear water
accidentally one winter and cracked the case. I now remember to run
antifreeze into it when winterizing.

thank you richard, i was looking at this one last night on utube, it also turns up to clean it out. it is not breakable and it can

clean it out till it is clean enough not to bother you and barF, it is cheaper as well, I am very interested in a new design

that is over the top with this problem, like a lawn mower blade inside the black tank and chop up bones and sanitary napkins.

I like strong toilet paper and then i found gospa which i am trying to become the gospa king and toilet train all the gmc'ers to use

the gospa from home depot for 10 bucks. best thing since toilet paper.

http://www.homedepot.com/p/GoSpa-Travel-Bidet-in-Purple-GS-70/203357941

most people think you stick this up your a$$ but you just sit forward a little and without touching yourself

you squirt the water which leaves the nozzle at 45 degrees up on your ass hole at a great pressure that cleans you

very well. paper then is needed just to dry one's self, which is all this thin light toilet paper is good for, it is not good for

sanitary ass wiping for it is to thin. But i still like thick charmin paper that is like a towel like. but this will not go through the pump

and it may pile up in a corner of the black tank. I think that a blade like from a lawn mower with an electric belt driven motor to the top of it from the side of the gmc 12 volt, one could chop up almost anything put in the tank plus a 120
pound air pump sprayed in the back tank on the end of the mower blades that would bring out the corners, or have a circular tank

to match the mower blade. so any ideas i am open too a new poop plan. mickey Anaheim ca. 77 palm in go spa.

The gospa is king..... !

I was told if you park a long time that you keep the gate closed but the 3 inch is put to the dump at all times while parked. then once a week you open the gate and empty. So this can be good to have both big gate and marcerator.

The closest thing to a problem I have had with it is it will trip the self resetting circuit breaker once in a while, but only when it is really hot outside. I still have the capability of dumping with the 3" hose but have never had to use it.

The one I had with cracked impeller probably froze. I bought it at a yard sale for 20 bux, and it looks new. JimK has the kits cheap so I will get one some day and fix it. In the winter it is good to have antifreeze rather than it be dry. If I spend another winter in Mo. I will just snatch it. I have them so I can change them quick.

Mine's been pretty near flawless so far. The coach came with some "gifts" from the PO, and who knows how long they'd been in there. Anyway, the macerator didn't want to power up the first time I tried to use it. I crawled underneath, and discovered (to my great relief) that the motor shaft extended out the back of the unit, and had a big ol' screwdriver slot. So all I needed to do was to take my big ol' screwdriver, give it a twist, and I was off to the races, dumping my blackwater tank in nothing flat.

I'd never own a coach without a macerator. It takes the one really unpleasant aspect of RVing down to a very minor annoyance at worst. I can't say it'll grind logs (that's literally logs in this case) or even Mickey's 12-layer superpaper, but it works for everything I've tossed down the proverbial crapper.
