Check-Valve Location on '06 Endeavor?

Before I pull off that big white water-bay panel again (Oh, how I despise that job!) to look for the water check-valve, can someone point out where the valve is located? Is it up next to the reel, or down by the pump itself?

In the process of trying to find a replacement hose for the water roll-up reel, I realized the check-valve isn't working. Turned on the pump with no plug in the hose-end and I got my brand-new tennies soaked before I could shut the pump off .

I'll probably have to take off the big panel anyways when I get my new hose, but I'm hoping that maybe the valve is down by the pump (fairly-easy access) and I'll be able to swap the hose as well, all without removing the panel. Yeah, wanna bet?

Nothing? Anyone replaced their water check-valve? Or know where it is?

I was always under the impression the check valve was in the pump itself. If it's bad, when you hook up to shore water, it will fill your fresh water tank. That's how I know the one was bad on my '06 Diplomat. Hope this is helpful.

Are you asking about the check valve in the city water inlet? If so, it's in the fitting where you connect the city water hose to the coach. That unit can be removed without disassembling anything else, usually.

Our Diplomat has a green handle that is turned counter clockwise in order to fill the on-board water tank. This is where my checkvalve is located.

Just above the green handle I have a black cover panel, and I was able to reach the checkvalve through here.

Look at this thread and go to post no 5.

I don't remember seeing a check valve in mine. As a suggestion though you might be able to trim some of that plastic off the bay cover for easier access. Most of it is for looks. I was tired of trying to take my off for various issues and cut a lot of it away. After doing that I added a second in tank sprayer on the black tank near the corner where the sensors are located. Using quick disconnects the water can be switched to either sprayer now.

Thanks for the inputs. With the hose-reel, mine has to be either just upstream of the reel itself, or down by/within the pump.

With my previous rv's, the valve was right where the external hose connected to the inlet fitting, but I think it's different with the reel concept. I'm going to have to look further in the pump area too.
Just don't want it to be something I have to remove that big panel for .

Hendrik - it's been a long time since you've been to Curry Hammock SP, maybe you need to stop in and crawl back there again to help me, like in your pics.

Failing all that, I'm just gonna use a plastic hose-plug I found, and forget about it.
