Anyone know what to do with black macerator hose

I have no idea on our 2018 Dynamax DX3 what to do with this black hose. I just know it fills up with the black tank, no switch, and has to be dumped along with the regular septic tank dumping or it smells in that compartment. What is is for? Just a pain in the neck to me?

I don't fully understand the situation.
The black hose is just like a sewer hose. Keep your dump valves closed all of the time. It should not fill up with the black tank unless you have an open dump valve.
When you black tank is full insert the black hose fitting into the RV park dump. Make sure that the gray water tank is at least 1/4 full. Locate the pump switch on the right side of the sewer compartment. Pull the black water valve and turn on the switch starting the motor. Let the black tank empty. Then use the black tank fllush system to rinse the inside of the black tank. Run water in there for several minutes. Then pull the valve for the gray water to flush out the sewer hose.
Look for somebody at the RV park to help you.

Well the main hose to dump (orange just for reference) is for both black and grey tanks. The black hose is very small, maybe 2" and short, wouldn't reach to most connections. I also don't see any switch on the wall. If I pull the black handle it will dump the whole black tank. The small black hose is just there with an end to put into a sewer connection but again so short and small what good is it?

I've never had a connection that I couldn't reach. The hose does stretch.
I'm not near my rig at the moment, but if I recall correctly there are two switches on the right panel. one is a light switch, the other is the macerator switch. Maybe some other member can take a photo and attach it to this thread.

That small hose is the primary dump hose. If you open either dump valve it will fill up. You now have a mess on your hands because to empty the small hose you have to take the screw on cap off.
The way it should work is you take the big cap off and place the end of the hose in the RV Parks dump hole, secure it and then if you want you can leave the gray tank open and the grey water will empty as you use water. When it is time to dump the black tank, open the valve and turn on the macerator pump; it will be a black rocker switch on the panel that has the monitor panel and valves for low water drain. Once you turn on the macerator pump the small black hose will look like a snake squirming around and it lengthens, too. As soon as you hear the pump spin without any resistance, turn it off. You are empty and don't want to overheat the pump. With valve closed, I lift the small hose to drain out what is left and then cap the end and stow away.
This is the method I use for our DX3. Other's may not like leaving the grey tank open, but in decades of RV'ing and more than a dozen RVs I've never had a problem.
Might also check the documentation/owner's manuals for more precise info.

Why use a macerator to begin with? That hose would need to be flushed out as well. Iíve never had one so please enlighten me.

If at a location where the 3" stinky-slinky can be used it would be preferable over the macerator.

If the waste needs to be pumped up, or over a long distance, the macerator would be the best/only choice.

Black hose is your dump hose. It’ll expand to like 3x in length when pressurized. Don’t be afraid to stretch it to get it where it needs to go. Also 2” is plenty when putting it under pressure.

As to why use macerator, I do it because it’s so fast. Definitely faster than a gravity drain. I don’t bother flushing it because you can just throw the cap on and it stays water tight. Other than flushing with the grey that is.

I find the whole process way cleaner/contained than using a traditional drain. So much so that I have yet to hook up my rhino hose.

What FOURWHL said.

Personally I hold all water/sewage till tanks are near full then dump.
I also run the macerator during the grey water dump to clean out the pump. After the grey dump leave the valve open to help drain the 2" black hose out before capping and stowing then close the valve.
