Black tank won't take water

Since the valves reduce the inside diameter, I wanted more volume. I don't know if this actually accomplishes this, but things seem no different in the rig. I run my rig at 60 psi, so maybe that makes a difference. Everything stays connected, even durring travel. Just hook in the water hose and done at setup.
FYI....Alliance recommends 40-45 PSI.

agreed and like my shower damage repairs, I am eliminating all the fittings that are not pex. Pex can more than handle 60 psi. My shower was a failure of fittings and the shower pan install. My shower pan wasn't even secured to the floor. I guess it is the risk and work I am willing to endure, while I eliminate the weak points, that should have never existed. Saying that the water is all PEX is a bit misleading in my opinion.

Believe it or not, because of the bends, you might get just a little less flow running through both feeders. Not significantly less but a little. Just a point of interest, not being critical by any means.

This is my control panel Mod, since we are sharing. Since there is a check valve on the backside of the flush connection and the Rinse connection is well above the tank level. This setup adds shut off valves to either side and I have been running it this way for 3 years now. When I think about it, running 2 separate hoses, because a check valve COULD fail, then I would be affecting the main water supply instead. In other words, same problem either way. I have disinfected 24" water mains before, so I guess it is not a fear of mine. I guess you could even throw in another check valve if you wanted.

This setup allows me to use 1 hose, 1 flow meter, and I just simply throw valves to direct flow. The hoses are $11 mixer hoses used for washer machines. I also carry two (2) Camco 25' EvoFlex2 collapsible hoses. They save sooooo much storage space! I only need 25' to date, but I have a backup plan with the second one. They are very tough and easy to deal with on a cold day.

Note: The hoses are twisted, because it removed some tension to the 4-way garden hose splitter.
That’s cool

is there a link for the 4 way valve as well?

Not sure I understand your answer. You have 2 houses from the splitter going to each inlet side. You say you think it increases your volume but those 2 hoses are going to one inlet so you are back to the same volume once connected. Not sure I understand that thought process?!?!
But I like the idea of one hose connecting.

The hose 4-way valve reduces the flow to abt 3/8"...Allowing the 3/4 hose to feed two 3/8" hoses, possibly makes up that reduction by the 4-way. I am not saying I am correct, but just using Jack Daniels math, that is what I did...LOL

Still not help in where this valve is, I think it could be under the stairs behind the furnace, no access to it. There is nothing under any sinks .

Yes its warranty work.
Warranty work just finished with the black tank flush blockage as noted above. Result was that it was plumbed wrong at the factory. Hard to believe when there's only two lines (one to check valve behind sink and then to black tank). Murphy's Law
