Mascerators

I've had both good and bad experiences with mascerator pumps. They'll work for a year or so and then burn out. I've been tempted to try using a 1 hp garbage disposal and creating my own. Several YouTube videos on how to do that.

My perception is a moneymaker (for the sellers) based on a non existent problem.
Black water tank problems center around not enough water in the tank to move the solids.

I have been in places where gray water is OK to let fly. In Texas, provided the landowner allows it, it is just fine.

Black water... different story. Illegal to dump anywhere.

what I have done is place a "blue boy" turd tank in my truck's bed. I then used the macerator pump to empty the tanks into that. Then, I drove the waste tank to a nearby dump station, hooked up a hose, and let gravity do the rest. Since the pump did the heavy lifting of the water, I didn't have to, which makes life easy on the back.

We go to some areas where there are no hook ups and are alowed to let the gray tank to drain on the ground. Is there a way for it to drain without the m-punp ?

Where are you ALLOWED to just let it drain on the ground?

The portable ones work just as good as the other. With the portable one, you can change over to the original drain. The portable one fits on the end where your large dump hose hooks onto. You don't need hose supports that are required in some campgrounds for your large drain hose when using the small macerator hose

x2. This helped a lot when I had an impeller jammed due to a bunch of cotton stuck in it (no clue how the cotton got in there, other than allowing a female acquaintance to use the bathroom earlier that day.) I just picked the stuff out, then used a flat bladed screwdrive to un-stick the impeller, put it back together, then continued emptying the tanks. This flat headed screw is covered by a rubber cap on my FloJet.

Before the depression, I did a lot of boat work. I got to hate macerators (except for the money they got me).

If you do install one. Make certain that the installation has two features:
First, you can still gravity dump at least the black tank. Both would be better, but cannot always happen.
Second, the system should be able to isolate the macerator so it can be removed for repair without a huge spill.

I have known some in our RV group that have had the same pump installed for years and had no trouble at all. My home dump is next to my driveway, so I don't need one.

Thanks lanerd. All good info.
