9/32?? What an odd choice by the designers -- not a quarter or five-sixteenths? Very few standard wrench sets include a 9/32 wrench.

Oh, well. If I ever have the need to do that repair, I'll use your workaround!


The wrench goes across the flat on the shaft under the impeller.

The extremely dry vegetation at Quartzsite could use your gray water.

I've never had a 'stuck' impeller not have I even given the shaft a twist before had...just hookup/power up and use it

Disassembling is easy....and not messy
I only do it AFTER running clean rinfse/flush water thru it

1. Remove the 4 acorn nuts at the top of the pump assembly
2. Pull the top sewer adapter away from the pump (be careful with the the gasket)

At this point remove anything wrapped up around the chopper blade. This may be all you need to do.

3. Remove the chopper blade assembly by gripping the motor shaft under the blade with a small pointed vice grips and remove the nut holding the chopper blade.
4. Now remove the pump assembly, being careful with the next gasket. Examine the rubber pump impeller. Replace if it has damaged vanes.


Reassemble in reverse


20 minutes R/R

I have had mine for 14 years. I use it to dump the tanks at home every time we get back from a trip. I have never disassembled the head . It has worked with no problems for 14 years.

Does anyone know if the manufacturer recommends maintenance at a specified interval?

My macerator just arrived today -- probably won't get to unbox it tomorrow due to family obligations. Maybe the manual will shed some light on maintenance requirements.

It's really quite a reflection on the mindset of an RV enthusiast that I am so excited about this sewer pump. I am sure that most non-RV folks would think that I have lost my mind.

But by making it easy to clean out the tanks at home, this new toy will mean that we can much more easily use the trailer as a "guest room" when we have company visiting us. And we can stop using public dumps as frequently as we used to.

OK, back to holiday preparations!!

I absolutely love my Flojet macerator and it's been trouble free in the 3 years I've used it. The one thing I do make sure to do is each time I use it I reach down inside of it with a needle-nose pliers and remove hair and debris from around the blade. Like anything mechancial there always could be a problem so I do carry a backup "stinky slinky" but feel it's unlikely I'll ever need it. If a failure is a huge concern I think you can get a replacement motor to carry as a spare for roughly 1/2 what the full unit costs.

mtofell, thanks for that tip -- I did not realize that the "guts" of the machine would be accessible without disassembly.

And yes, we have no intention of getting rid of our dear old slinky. I will use the Flojet at home (because the slinky won't work uphill), but we will use the slinky while traveling.

Well, I have unboxed it and am examining the contents of the package. And to answer my own questions, yes, there are procedures in the manual for repairs and maintenance to be conducted by the end user. But they are not simple tasks -- this is not something I will do until I have to.

As far as I can see, there is no required annual maintenance.

The instructions do not expressly say "this can be powered directly by an ordinary deep cycle battery." But since it requires a 12 volt power source, and it is designed for RVs, I think the answer is yes, direct-to-battery is OK.

They also say that if the cable run to the battery is more than 10 feet, use 10 gauge wire, rather than the 12 gauge wire that they provide.

Finally, they say that if you use alligator clips (presumably to the battery??), they have to be rated at 20 amps. So don't use a spare pair of flimsy clamps (which is what I was planning to do until I read the little manual carefully). [emoticon]
