Portable Macerators

When I first bought my GMC in 1992 and had to dump a black tank for the first time, I decided that from my boating experiences that I was definitely
going to install a "marine type" macerator. I grouped together the parts needed and installed a system. NEVER EVER was I sorry and NEVER EVER did I
have to mess with those nasty expandable waste hoses, gutter supports, donuts, etc.
My permanent solution includes a standard PVC "T" fitting right after the dump valve which continues the old line plus the "T" goes through a standard
rubber bushing where the macerator is directly attached. Output of the macerator goes through a permanent heavy duty rubber discharge hose to the
back bumper where a standard hose bib is attached. I have a special orange "waste hose" (from Amazon) that is used to discharge to the dump site.
Power is off the rear battery and switched on/off by a hidden waterproof switch in the rear storage compartment. Didn't want to mount the switch
someplace where someone (kids, curious adults) might flick it just to see what it turned on. I can now dump the entire waste tank faster and cleaner
than you can hook up the standard waste system. Usually, I don't even hook up to a waste connection at a campground because the permanent macerator
driven system works so easily.
The parts are standard parts from RV shop (or Amazon) and Home Depot and only takes a couple of hours to install. The macerator is mounted between
frame rails to the bottom of the rear floor (using a 2-1/2" wooden spacer) where the floor starts to slope up (between my rear Gaucho seats) and the
discharge hose and wiring runs along left frame rail. Really simple to install in a couple of hours (honestly) using only a drill, saw and soldering
gun. I can send a list of parts and photos if you wish. I recommend a permanent installation and keeping some "screw on" hose caps to re-attach after
discharge. You can probably assemble these parts much cheaper than the listed kit price.
 
Ronald,

No question whether that will work. BUT, remember that the lugs on your
sewer connection were never designed to support a heavy motor at the end of
a lever arm and with lanyard (hose) to yank on.

Back When, I had a macerator, water powered and very light weight, attached
that way. I'd just pulled the handle on 50 gallons of black water when the
mounting lugs on the macerator itself failed. A 3" geyser of black stuff
came gushing out. I was able to reach the valve quickly without taking a
bath, so only a fraction of the waste hit the ground.

I was lucky: I was alone at the family farm with 850 acres of privacy
protection and sandy soil. I'd just, for some reason, bought several
gallons of Chlorox. Later that evening we had a 3" rainfall.

In that case the manufacturer admitted problems with the device -- and he'd
designed and built the whole thing. Thetford, Camco, Valterra, etc.,
aren't going to defend the strength of their mounting lugs.

​If I HAD to use that sort of arrangement, I'd mount the pump on a portable
platform to set on the ground, with a short 3" hose to the RV connection.​
But I saved money by mounting it (actually one for gray and one for black)
on the GMC's frame.

At an RV show, I purchased a macerator that is completely water powered. It connects to your sewage drain, has connection in for typical home water
hose to supply water power, and connection out for typical home water hose for output. Put the output hose in the dump point, turn on the water line
full blast, water pressure breaks up sewage and forces it out into the dump point. I have successfully dumped thru a 50' hose.
Turning the control valve also sends clean water into the sewage system to flush out the tanks (back flush).
This little gem cost about $100. I purchased it after seeing another GMCer using one.

One of those showed up in my spares. Since the new coach has one installed permanently I passed it to Tony Bennett for his toy hauler.

John et all,
Installed my first macerator in 2001 on our first coach a 77 Eleganza II. Their have been and are several different designs and all work well. The features that I have on the installation that I use is that I have moved both the dump hose and the macerator outlet to the drivers side just in front of the rear bumper. Moving the centered rear outlet gets it out of the way of the tow hitch if you have one and do tow. I also use quick disconnects and a one inch hose which can be extended if you need more length. The switch is located up inside the generator compartment. The drain layout on the Stretch is different and I feel one of the best designs that Buskirk had for the outlet piping.

As for parts:

The 3-in X 1 1/2-in rubber eccentric coupling used in this design is typically stocked at most big box stores and will need to be ordered.You can also get a black PVC version.

Tom,

That's the kind I told about breaking on me. It was an early model. When
I started to raise cain about the failure, the manufacturer told me that
those almost put them out of business. They kept changing the plastic
trying to stop the breakage. Finally found that the grease being used on
the seal would attach 'most any plastic, including Lexan.

I may still have the replacement somewhere if anyone wants it.

It's still more trouble than a mounted electric one.

Another question for macerator users:

I have a twist on macerator, but have never used it. So I have absolutely no experience with a macerator.

The macerator needs to be turned on and off manually. That seems rather inconvenient while taking a long shower(unless you have a switch within reach
of the shower). So that would be a mark against using one? Where the gravity 3" hose never needs to be turned on and off while camping.

The only real positive I can think of on the macerator is that it will pump uphill, and long runs. But at normal campgrounds pumping uphill is hardly
ever a issue.

Anything I'm missing? How/why is the twist on macerator better/easier than the 3" gravity hose in a normal campsite? You still need to twist on and
off both styles.

I would like to use my twist on macerator, but just haven't seen it as a advantage. Opinions?

Thanks, scott

We have a twist on macerator that. We use at home and pump through a 50 foot 3/4 inch hose. Works great. Can't really see using at a camp site or dump station though.

Scott,

When parked with sewer connection, it's OK to leave the GRAY water valve
open -- NOT the Black or Combination valve. The solids need a lot of water
with them to keep them liquified enough to drain, regardless of whether you
use a macerator or gravity drain.

If you take long enough showers to require dumping the tank, you could rig
multiple control switches, with one accessible from the shower. I suspect
most of us just take "Navy Showers".

After you've visited enough campgrounds, your count of "too high" sewer
hookups will grow; most campgrounds are not designed for rigs as low as
ours. And you may visit homes where a macerator is the only way to use
their sewer cleanout as your dump station.

Finally, most important to me: The macerator hose is smooth inside and
doesn't collect debris, especially if you can dump Black followed by Gray.
So, it doesn't need rinsing and draining. It stows easily in a permanently
mounted tube rather than being like a monster wet noodle that you've got to
stow in a non-existent compartment.

I've got a LOT of years' (60+) experience with both "stinky slinkys" and
macerators -- I AIN'T goin' back!

(But I'd permanently mount that "twist-on".)

With the gray water tank valve open, and the black water tank valve closed. Is the gray water able to travel through the macerator when the macerator
is not energized/turned on? And still gravity feed?

If yes, then I can see the macerator as being the way to go.

I travel with a couple of females at times, and a navy shower could be a issue! They love my tankless water heater..

No, the macerator will not pass liquid when not running. It is, however,
simple to install a bypass for continuous draining as you suggest.

Ron,
My coach is plumbed to come off the back of the macerator with 1" pvc piping and Tee each direction with a shutoff valves and adaptor to a 3/4" garden hose on each end. Hook a garden hose female connection coming off the shutoff valves and loop it thru a pvc sleeve inside the rear bumper.
Depending on which side the dump station is, disconnect the opposite side pull the garden hose thru the sleeve and open the shutoff valve on the dump side and turn on the macerator pump.
Really works well will very little mess or cleanup.

I have a 78 Royale w/two tanks, and not much room to mount the mascerator.
There is a tri-angular space in the drivers side rear corner where it fits,
but the discharge points to the frame when the mascerator is connected to
the area of the drain pipe that will allow either tank to be drained
separately, and still have the 3" stinky slinky available for use. I used
a hole saw and cut a hole in the frame, and plumbed rigid pvc to a shut
off, then converted it to hose male threads with a threaded cover. When I
want to drain the tanks, I hook up a short piece of 3/4" garden hose, drop
the end down the dump station, flip the switch hidden in the generator
compartment, pull whichever tank valve needs dumped, and a couple of
minutes later, all done. No mess. I usually dump the black tank first, then
the grey, that way it flushes out the waste from the hose. The way I have
the system plumbed, no water stands in the drains, so, no winterizing is
needed.
Works on the Royale coaches very well, particularly with the wireless air
controls. One of the preset buttons lowers the back of the coach, and tilts
it, too. When finished, a single touch on the other preset button, and I am
back to ride height. I still have the 3" slinky drains available if the
mascerator fails.

The main problem with Portable macerator is that majority of the coaches
has only the Black tank.
When one dumps there is not gray water to flush out the black crud and
smell, so storing it is a smelly mess.

Scott,

I'm confused!

Why would you want to turn on the macerator when taking a shower?

Avions have a 40 gallon black tank, no gray tank, a 38 gallon fresh water tank, and level indicating lights on both which come on at
1/4, 1/2, 3/4, and full.

I monitor the level indicators and when the black tank gets 3/4 full I know I'm going to have to dump soon.

Photos of my macerator installation on the Avion:

Photos of a Jabsco macerator:

Photos of the quick disconnect SeaFlo macerator:

http://www.gmcmhphotos.com/photos/g6769-seaflo-macerator.html

This is what I will install in the Kingsley because it is a quick disconnect model. The mating piece to the macerator inlet replaces
the rubber hose and screw clamp inlet connection for the Jabsco. A plug in connector will be used for 12VDC and screws retained in
the bracket with wing nuts to hold the macerator to the bracket. This will allow the macerator to be replaced quickly if and when it
fails.

Rob,

My coach has a 16 gallon gray tank, and a 23 gallon black tank. My shower head has all the water restrictors removed, so it moves a lot of water. And
the tankless water heater provides never ending hot water(as long as you have water). So taking a shower in my coach is no different than taking a
shower in ones home. Except for the elbow room!

I have not had a chance to measure how many gallons of water one would use while showering in my shower, but it has to be more than 16 gallons. I
assume my water flow with a 50 lb water regulator inline is at least 3.5 gallons per minute(and that's a wag). So a 5 minute shower will drain 17.5
gallons. Even a 2 gallon a minute flow only gives one a 8 minute shower. I can shower within these parameters, but the ladies??? And I want to make it
as comfortable for them as possible.

So that's why I would need some sort of on switch for the macerator. I don't have the the large holding tanks that you have. But if my tanks ever go
out, I'm going with the large single tank.

A float system inside the tank to tell the macerator to come on line automatically would be nice! Hint, hint!!

Scott

When I read that I assumed that Scott is hooked up to city water, leaves the 3" hose in the drain and leaves the dump valve open all the time (ignoring possible solids buildup in the tank when using the stool) and takes 60 minute or longer showers.

Emory,
Now I'm confused!!
60 minute showers??

But to answer your reply.
Yes- I do hookup to city water while camping.
Yes- I do have my 3" stinky slinky hooked up.
Yes- I do have my black and gray valves open all times while camping.

Things you did not respond to.
Yes- I do fill my gray tank then drain before I disconnect, after the black tank has been drained.
Yes- I do drop a 20 lb of ice down the toilet to the black tank while enroute to clean the tank.
Yes- when I get back to storage I redump the black tank, followed by a flush, then the extra fresh water gets pumped into the gray tank then dumped to
wash the hose from the black mater. All with the front wheels on blocks and the rear bags deflated.

I'm I missing something?
I am assuming the shower water goes to the gray tank??
Scott

Scott,
In a Royale Center Kitchen, at least ours, and every other one I've seen, the ONLY thing that goes into the grey tank is the kitchen sink...
