Bypass Valve

I just purchased a 2020 2507s,today i was going through it and checked to find the bypass for the HW tank.It is already winterized from the factory,my question is where is th bypass valve.The valves are there for h and c but no tube between them with shut off. Is there another place to bypass? Any help or thoughts appreciated. Thanks

There is no middle tube just two lines with shut off valves on each h and c.

Some systems use a diverter valve. This valve does not shut the water off, it changes the direction it goes. In your setup, the valve on the blue line will allow water into the hot water heater, if you turn it 90 degrees it will send the water into the cross tube. On the red valve, it allows flow thru the heater and into the rest of the rv, when the valve is turned 90 degrees, it allows the water from the cross tube to flow and stops the flow from the hot water tank. Hence, not a shutoff valve, its a diverter valve. Hope this helps

I should have read another post. If your system doesnt look like the photo, it doesnt use a diverter valve, sorry. Maybe you could send a picture of what it does look like.

Don't know how you would bypass it without a cross tube. There are a number of ways that they've come up with to plumb these things - but they've all got cross tubes. I've attached a pic with a number of them. See if you can figure out if yours is like one of them.

Note that we're assuming you have a tank-type heater.

Here's a pic for how a 2 valve system works. It still has a cross over tube...just not a 3rd valve.

As others have said, a pic of your set up would help us help you.

My Wildwood 26DBUD has the same set up -- no cross over line, just a loop that connects hot and cold AFTER the shut off valves. I will get a picture of the set up and post it.

On some units the bypass is located in the water compartment. I'm not sure if that's the case in the 2507 because non of the pictures show that side well, but it's worth checking out. It could be located inside the outside shower door also.

It's really rough to see in the pic, but isnt there a white tube on the other side of the valves? If so, that's where the water will cross over.

X2. They're "pretty good" at making the cold line blue and the hot line red, but don't bet on the bypass line color, as they will often use whatever color is "handy."

I'm guessing if you were able to get a better picture, your system looks similair to this:
