Black tank replacement

Bill,

The tanks were upgraded in either 17 or 18 - they did listen.

Question:
Is the black tank flusher mounted opposite to the drain end of the black tank?
The reason I ask is when my rig was new and I used the flusher you could clearly hear a "whirring" noise coming from underneath.
My flusher still works but I don't hear the whirring noise leading me to believe it is no longer spinning. My tank sensors also show full all the time. I think the spinning flusher helped keep them clean.
If so, and it's mounted opposite the drain I'm guessing taking down the front edge of the Coroplast is the easiest way to get to it?

Daryl,

I would not do anything with it. One of the primary purposes of the flush is to put water in the tank. Many rigs do not have flush systems and work fine by just putting water in via the toilet.

AZ Traveler - That is good to hear- I appreciate the update. Thanks, Bill

Mine is on the opposite end as the drain but it is a 2015. I would think they were the same but I dont know for sure.

On my unit, the flush fitting is on the opposite (forward) end of the tank from the drains. Lucky23's second photo shows the drain end of the tanks. I don't think there are any moving parts in the flush system. I think it is just a nozzle with a few holes in it to spray water around.

I just replaced both the gray (bath) and black tank valves. The original ones were getting a little hard to pull. A lot of people talk about stranded cables from the factory; my unit (2017) had solid cables from the factory; replaced them anyway. My problem was not the type of cable; it was they way the factory routed and secured the cables.

While I was working on it, I found that some of the sensors were leaking and rusted so I also replaced all the sensors. My next project will be to replace the sensors on the galley gray tank.
