Anxious to know what the issue was.

Has to be something in the hose. Ironically, I just replaced my impeller about 2 weeks ago.  What a difference.  I have no idea how it worked previously since all the rubber blades were gone and literally disintegrated.  Anyway, on the edge of my seat with anticipation. 😂

I think if it were me having a problem like originally described I would probably do the following:

1.  My PC has a cover on the big hose dump port and on that cover is a regular garden hose connection with a cap.   

2.  I would take one of my old (I have a couple of used ones I keep for various uses) washing machine hoses (they have female hose couplers on both ends) and attach to that dump port at the hose connection, leaving the cover in place.

3.  I would then hook up my garden hose to the free end of the washer hose.  I would also have my standard 40 pound rv hose regulator hooked up to the garden hose. 

4.  I would make sure both the black and grey tank valves were closed and I would turn on the 40 psi fresh water hose, forcing a back pressure into the macerator pump which would already be turned on and see what came out, if anything.   

5.  If nothing came out, I would know the problem was probably in the pump or right at the pump.   

6.  If she no go, I would disassemble the pump.    I am reluctant to mess with my pump because I have had lots of problems with the way PC mounted it and I have pretty successfully remounted it to better align with the rigid pvc from the tanks.  Essentially, road vibrations would cause the bayonet to pop a leg and I would have to replace it as I recall.  I modified it soon after I got it ten years ago last month and it is storage now so I can't recall in detail just what all I did to elevate the problem.

I suspect the whole process would take less than ten minutes.  Hooking up a short hose, hooking up a garden hose to it and turning on the macerator to see what happens?   Seems simple to me.

Slight topic detour - our bayonets cracked not long after purchase. The repair shop we took it to was aware of a problem with faulty parts, contacted the manufacturer and it was repaired free of charge. No problems since. It was not associated with the way it was installed.

Was that a manufacturing issue around 2013 when your PC was new?.....Just trying to put a timeline on the window of poor manufacturing of 3" sewer components with bayonettes.

The bayonette breakage was most likely caused through the use of an inferior formula of plastic which could have affected every 3" sewer component with and without bayonettes.  It simply shows up first in the highly stressed bayonettes.  Maybe as age and vibration continues, other failures within the sewer system may occur.

I assume the parts were imported from China.......enough said about that.

Iím guessing weíre talking about Thetford part #70405.   That part has always been a weak design. Iíve never been able to find an alternative. If you wait till summer itíll cost you $55-105 if you can find one.  Buy it in the off season and itís usually in the mid $30s.  I bought an extra after one of the tabs broke on a horrific road in Texas.

Done working.   Took me that long just to read the process

Our PC was picked up May 1, 2013. I don't know the time frame for faulty parts. We were just lucky the shop we took it to knew about it and bounced it back to the manufacturer.

Hi all - sorry for the radio silence, busy driving home. Good ideas to try, once I can find a little help. Back problem makes it difficult to get down there to work on it. Iíll try to con one of the kids into helping (maybe if I donít tell them what it isÖ  ;) ). Itís being winterized and stored today, but maybe I can get it some nice day yet this fall and play around with it. Thanks again for all the ideas.
