On never mind, I see Herk did the cutoff valve. That's way fancier that what I was thinking of.
My thought was that if the flush valve got stuck open, it might take too long to run outside and shut off the water (especially if I was not particularly dressed for such a sprint). It also makes servicing and washing the Hopper easier without removing water from the whole camper.
Since I needed to repair the flush valve anyway, I installed the shutoff and the wash down sprayer at the same time.
As you can see from my thread, I did NOT use the Thetford flush valve "nipple" for the wash down sprayer because that required me to hold the flush valve open while spraying and reduced the water pressure to the spray head. This caused me to use way more water boondocking than I wanted. By adding a "T" above the main shutoff, I can use full system pressure when cleaning up; then just one flush to dump the bowl.
I added the wand shut off in case the spray head or hose developed a leak. That way we cold still use the Hopper until it could be repaired.
Note that I left the Sharkbite disassembly tool on the first pipe fitting to remove since it is a tight fit between the Hopper and the wall.
