macerator pumps, Liberty Coach

[win42]

I have owned my 91 Royale nine years and have wondered what use the macerator could provide. I was quite sure it wasn't a deterent to tail gators. Mine is in the top of the black water tank and has a hose runing to the rear of engine compartment. I had always heard people that own Prevosts #@it doesn't stink and figured this is how it got into those little plastic bags.

Seriously there have been times when I'm sure, used properly hooked up to a dump site, it would help keepthe black water emptied. All campground drain hookups are higher than my gravity outlet. Some of you have had success using the maceato in this mnor? please tell me more.
It's been a lonely 9 years not knowing any oher Prevost owners.

I don't personally have a macerator, but I can think of some ways it would be used. Have you ever gotten home from a trip, and weren't able to dump? Like you dumped before leaving the campground, and then Junior (or was it Missus), had to use the potty before you got home?

With a macerator you can hook up a standard garden hose, and dump all the way into your house toilet, or if you have a small sewer access, you can do the same. Not being able to dump at home has been an issue for me in the past.

Obviously, you wouldn't want to use that garden hose for much else??

Win 42,

Glad you are here and after a few weeks, you may decide lonely wasn't so bad afterall.

Just as Ray stated, we have a sewer cleanout right behind the hedge in the front of the house. A 20' hose will reach it and you can pump the black water tank out in short order with the macerator.

I also run into RV sewer hook-ups that are high enough that the tank doesn't fully drain or leaves the hose full. In several places where we dry camp or just have power, we use the sewer tank to garden hose adapter to drain the grey water into a convenient spot. I'm sure this is unheard of in the east, but here in flyover country, the world is our toilet, so game on.

Ah, sooner or later the Black Tank discussion has to begin!

Wouldn't have a bus without a macerator, although on our old crummy Liberty it had to be primed every time we wanted to use it. With our new wonderful Vogue, it works every time and even chops, slices and dices better than a RONCO.

Some folks make up a 4" sewer cap with a garden hose adaptor on it for use at most parks and don't use the flex piping for the black tank. In a single waste tank bus, this is the real deal; simple, no flex hose and you can dump the tanks from the inside (given the control system) when necessary.

Slick.

Some people in Tennessee prime their macerator by turning it on and then sucking hard on the hose. I guess it works, but wouldn't recommend it to anyone.

Oh and most importantly, win42, please feel welcome to this crowd!! The old Groucho Marx remark of, "I wouldn't want to be in a club that would have me as a member," might fit, but we have lots of fun here and don't know the difference, so ignorance is bliss, I guess.

But don't go in the shower with Jerry. He is a really big guy.

"Some people in Tennessee prime their macerator by turning it on and then sucking hard on the hose. I guess it works, but wouldn't recommend it to anyone."

I see by that remark Lady Helen is going to need to hit you about the head again.

BTW, I was told by an acquaintance that he would empty his tank by using the macerator because the outlet was pointed out the driver's side. His thinking was it would spray into the median. He fessed up however that the first (and only) time this wizard did this he never considered the huge air flow around and behind a Prevost moving at highway speeds. It seems the contents ended up all over his new Jeep GC, in all the joints, in the vent under the windshield, etc. When he shut down for the day the results were dried all over the side of the Jeep, in the door gaskets, on the wipers, etc. Washing it must have been fun.

When I was stuck in the middle of the yard for over a week when I had my axil problems, a macerator cam in real handy. I could have been the original cuz it burnt out after running it several minutes. I now have a shiney brand new one with led lights on it. Looks neat.

With a macerator, you can do one of the things that plumbers say cannot happen. They say poop doesn't run up hill, but it does woth one of these fellows.

My aren't we thin-skinned. The 'guy in Tennessee,' is the chicken farmer who lives next to the now-defunct BG facility near Knoxville. (Many stories about him).

At one point there was a new fancy coach visiting there and the owners had two very large dogs. They decided to let the dogs run free while the coach was in the service department.

Before long, here came the farmer walking up the visitor's center, shotgun in hand. Helen, always trusting the best in everyone said, "Hey, that guy has a gun, what's he going to do?"

I said, "I think he is going to shoot the dogs."

Out from the sales department came two sales guys with their Hawaiian shirts on (no socks) running toward the chicken farmer.

Indeed, it was his intent to shoot at least the two dogs for getting into his chicken coop. After much heated conversation, a financial transaction occurred and the chicken farmer retreated to his home.

Of course,later in the day, I engaged the chicken farmer in conversation and it was, well, a rather interesting chat. It was his sense that too many of the coaches being brought in for service were there needlessly, and that many of the problems the owners had could be repaired with what was at hand; the macerator pump being just one of them.

He said that timing was everything.

And indeed, it is if you are attempting to prime the macerator by creating suction.

And there it is.

OK, I'll accept your story. I just did not want you spreading untrue tales about a fellow POG member.

I'll have you know I replaced the factory original black macerator hose with a clear one so I could monitor the oral priming process. As you said...timing is everything. Free advice: should you misjudge on the timing thing, do not swallow.
