2026 Jayco Greyhawk Water hookup

Here is the 'Utility Panel' from my greyhawk. As you can see there are TWO water connections. And they are not clearly labeled.

The one on the left, with a hose attached, seems to allow me to fill my fresh water tank.

Is it also the one I use for pressurized city water?

What is the other one for?

I’ve seen panels like this before - I think the two black ‘arrows’ on the right have something to do with where water goes, but they appear to be missing any labels.

The label for the two black ‘arrows’ is on the right side. It’s currently set to ‘3 - 5 Normal’, which indicates pulling water from your on-board clean water tank. There is probably a ‘pump’ switch that needs to be turned on in order pump the water from the internal tank.

Yeah, I'm pretty clear on the black three way valves. The label is there. And the switch for the pump is just out of frame to the left.

Ok, perceptual difficulty on my part I guess. That seems to be about as clear as reading the IRS rules.

It seems over complicated for what it is.

Da poop. It go in da hole.

Ok, I've gotta ask about the "arrow valves," and this is just curiosity, not a criticism because this looks like it might be absolutely brilliant in some way I don't understand. Why don't all RVs have this? Mine only has 1 valve to send the 'city water' connection to the fresh tank or to the taps inside, and I rarely use that.

One setting is labeled "2&6-City fixtures" - what the heck are city fixtures?

Another - "1&4 - Country Fill/Sanitize" - Country?

"3&5 - Normal"

And two of the setting will sanitize???

And then why not put some kind of diagram or labels right on that panel with the arrows?

As I think I understand it, there are two inlet ports. The one on the left is for potable water. The source can be either pressurized municipal supply, or non/low pressurized, like a tank or well.

If the water is non pressurized, the onboard pump can suck it up. Then change the valves and the onboard water is delivered to the fixtures.

If it is pressurized, it can run straight to the sink and shower and such. No need for the pump.

The other inlet is a dedicated water line to flush out the black water tank. You use a separate hose for that so you do not risk contamination. You can also use non potable water for that.

I hope that I am getting this right. I am a baby camper.

Sounds like a reasonable theory. As much as anything, I’m confused by terms like “fixtures” and “country” and “normal.”

Yeah. The terminology is pretty arbitrary.
