Black tank sprayer

Hello
I have searched and read many threads on black tanks, cleaning black tanks, and have not come across anyone mentioning what Iím about to ask.
The sprayer in my first Montana clearly sounded like it was spraying. Now the new 2020 3701lk black tank sprayer sounds as if it is being filled with just a hose.
I thought that this was not right so when I had it back at camping world. I told them it wasnít working right and of course they told me it was.

I was wondering if anyone agrees with me that I should hear a spraying sound?
Thanks, Bob

When our 2019 was new, when you used the black tank flush, you could hear it "whirring".
After a few months, no "whirring" but it did fill the tank for flushing.
It's on my "to do" list when I eventually drop the coroplast. I'm going to remove and clean it. I'm guessing the spray holes are "gunked" up.

If yours is anything like mine, not only do you need to drop the cloroplast, you also need to drop the tank to remove the rinser. There's not enough space between the tank and the frame to remove rinser.

Not sure you will be able to do anything to the spray nozzle. This is what our sprayer looks like at the front of the black tank. Not thinking anything is removable.

Thanks for the replies. I don’t have the tools with me to jump into this project right now. I’ll have to wait until we get home. I might drop the coroplast and take a peek in there.
Thanks again

Darn.
I was thinking I had a Tornado installed based on the "whirring" noise I heard when it was new.

There's another video somewhere showing someone installing a Tornado in their black tank.
If it's up against the frame and I have to drop the tank to reach it, forget it.
I've read running vinegar through the pipe helps clean it AND the sensors. Maybe I'll try hot water first, then vinegar.

Daryles,
You might try to use some black tank cleaner from Unique.

Be prepared for a shock when you open the belly. It's almost as unnerving as opening the basement utility space

Thatís enough room. A stubby screw driver and a sharp putty knife will get it out. Iíve had ours out twice to clean the super tiny holes
