FWIW, here is what I did. Macerator only...no 3" dump. Have a gate valve between the tank and Macerator in case the impellers go bad. So I carry spare impellers. Knock on wood...no real issues. I can pull into a dump station, and dump in less time than it takes for others with stinky/slinky. JWID

Thanks John.
I did not know that.
So knowing that, I can get by with a 7 minute shower at 3 gallons per minute.
Now it makes sense to hook up the macerator. I have 2 preexisting macerator on/off switches(generator bay and drivers seat). I just didn't want to have anyone inside the shower, and half way through, would have to torn the macerator switch on then finish showering.

I can't believe I've had this macerator for 2 years and not experimented with it yet....I guess I'm a creature of habit..

Thanks for the info,
Scott

1. I signed it as Emery, not Emory

2. You didn’t pick up that I was pulling your leg with taking a 60 min shower.

3. How could you possibly expect me to respond to those three items when you did not mention them in your original email?

4. I believe that Coachmen built GMCs had the shower going to the black tank, not the Grey tank. I think the kitchen sink is the only thing going to the Grey tank.

Emery,
We get lot of Coachman owners wanting us to reroute the shower to Gray tank.
Coachman did some strange things.

I was going to ask about low flow shower heads, I saw one on Amazon that
did 1.5, 1, and 0.5 L per minute, on the lowest, that would allow multi
hour showers. :-)

Scott,

I have one 40 gallon black tank for waste water, that's what all GMC's with one tank had; it fills the frame section behind the fuel
tanks.

http://www.gmcmhphotos.com/photos/black-tank-repair/p46639-holding-tank-repair.html

I really don't understand why Coachman went with two tanks; it seems to unnecessarily complicate a simple system.

IIRC the max flow from a GMC water pump is 3.0 GPM.

I take military showers:

1) Wet body
2) Wash with a wash cloth
3) Rinse body

If I have to wash my hair (hippy pony tail) it takes longer and a bit more water.

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

Rob,

Thank goodness for separate gray and black tanks. I've never, in any RV,
had truly dependable level gauges. Frequently, the first indication that
the gray tank is full is the puddle in the tub/shower. That's repulsive
enough -- I don't want to think about how bad it would be with gray+black.

No single tanks for me!!!

Ken H.

Several things:

My experience with on-demand water heaters is that you need enough flow for
the demand sensor to react. I have had trouble with those when using
low-flow heads, and that may be why the restrictors were removed. The water
heater that formed my experience was a propane unit in an off-grid house on
an island off Cape Cod (no, not Nantucket), and they had to run a generator
to fill up a rather large pressure tank, from which they would draw water
for as long as it lasted, and then they'd have to start the generator and
fill it up again. Everything was low flow.

I also use a Navy shower as Rob describes: Water on, get wet, water off.
Soap up, shampoo in hair, get clean. Water on, rinse, water off. With
endless hot water from a city connection and on-demand water heater, I
think I would need a continuous sewer hookup. The Redhead, when she can be
convinced to used the coach shower at all (she prefers the campground
shower, for some reason), has been perfectly willing to do likewise. (When
she washes her hair--all bets are off--but then the electrical supply is
also an issue.) But I've learned to depend only on coach water, and not
city water.

I've come to the conclusion that a full-time water hookup is asking for
trouble. I have lost one faucet connection, resulting in a puddle under the
coach that stopped growing only when I turned off the pump. With a city
water connection, I might not have noticed all day or all night. A leak
when on tank water is a 30-gallon problem. A leak on city water might be a
3000-gallon problem. At Mansfield last year, I had the uphappy duty to
report to KenHen that a city water hose was leaking so bad that the ground
in front of his coach was a growing lake rather than a drying one (the
first day of that rally was...moist). Then there's the issue that the
plumbing sees 25-40 psi on the coach pump, but maybe much higher on city
water, even with a regulator.

In a campground with full hookups, it's easy enough to pull out the
macerator hose and pump the waster tank into the sewer, and then use the
city water to refill the water tank.

I use my water tank as an indicator of when I need to empty my waste tank.
When water starts to get low, I figure it's going somewhere. Time to empty.
Ken can't tolerate the idea of a combined tank, because he's never sure
when one or the other of them will be full, and having city water running
continuously means they will get full more quickly and unconsciously, it
seems to me.

Ken,

You've never had an Avion, to measure the level in the black tank there are five lights in the panel which indicate Empty - 1/4 -
1/2 - 3/4 - Full and five screws in the side of the black tank.

Twelve volts is applied to each of the lights in the panel and as the level in the black tank goes up the fluid completes the
circuit to ground and the light comes on.

KISS principle at its best.

I've seen the 3 gas tank mod, I'd be tempted to do it, but use it to add a
grey water tank instead. But then you'd want more fresh water as well.

I have done one permanent istallation using the thetford sanicon pump ( http://www.ebay.com/itm/Thetford-70246-Sanicon-Tank-Buddy-Direct-with-21-Retractable-Hose-/222293134944?hash=item33c1b40e60 ) and will soon do another on my coach.
It is a pretty simple installation using most part in the kit and you will only need to add a couple of items like a hose clamp and if you are fancy a remote wireless switch ( http://www.ebay.com/itm/12-Volt-ON-OFF-Remote-Control-For-Seaflo-topsflo-shurflo-water-pump-/201536513050?hash=item2eec83241a )
You will of course use the wires, switch and fuse holder that comes with the pump, I did use the bracket as a rear support, it is just to flip it over and bend it a little, I did also need a 3" adapter ( http://www.ebay.com/itm/RV-Camper-Trailer-Plumbing-Sewage-Bayonet-x-Hub-3-Termination-Adapter/262783911195?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p 2060353.m2749.l2649 )to mount the pump to the original tubing and a hose clamp to secure it.
As the pump hose is flexible I did just route it towards the rear bumper and I will still have 17-18' of usable hose left, works as a charm Smile

Emery,
No offense meant.
It's not east easy typing on a old iPhone with sausage fingers! And don't get me started with this damn auto word check!!
I was just trying to explain my expectations with my sewer hookups, and limited holding tank capabilities.

I did not even know my shower gray water drained into the black water tank until last night. So much for commonsense prevailing.

Last but not least, a 60 minute hot shower is not a joke. But a reality!!!!! I just need a auto on/off macerator.....

Some great thoughts. IMHO I personally don't think you would be disappointed going with a mascerator no matter which way you go, the portable or permanent one. We also have one (permanently installed) and use it every time to empty the black tank. I would suggest going with the 1" hose (makes it very fast!). In our case we leave our hose attached to the macerator, and store it by capping the end of it and stringing it in to a couple of 2" PVC pipes through the rear bumper. Makes the dumping fast and clean.

I know it's already been said, but we just got back from a 2 week trip and we dumped every morning. The macerator made it quick and painless.
Camping world was clearing out their stock of old sanicon's and I grabbed one for 150 to replace the 30 yr old one that was on there. Changed it at our first campground of the trip. Quick and easy.

I dumped 10-14 times and never once got remotely dirty. Pull the permanent hose out of the 2" pvc that runs down the driver side frame rail and flip the switch. 2 or 3 minutes later flip the switch off and shove the pipe back in and roll on!

I'm still new to all this, but the PO installed a macerator and I like it. Just like several have said, 2 or 3 minutes and you're done.

I have used other motorhomes with the traditional gray and black tanks before and I was concerned that the combined tank on the GMC was not going to be as good. First time I emptied, I realized a few gallons on black water mixed in with 30+ gallons of gray water might be better than dealing with separate tanks. As mentioned above, the dreaded shower drain back up is always a bit of a concern.

For those with macerators, do you pump until the pump starts sounding a little different, and the flow slows? If you keep it running, it will continue to dump, but my thought is the pump inlet is not full and this is probably not good for the pump.

Tom, I believe as long as the pump is not run completely dry you're fine. You just need enough liquid to keep the impeller lubricated against it's housing. I run it until the noise changes and then another minute or so after that.

Always dump the Black first then followed up with gray to clear the black
ad the smell.
That is if you have the two tank system.
