I have an idea.

I am waiting for Willy's call to help him through an upload.

If there is a single "T" valve similar to a RV anti-freeze valve at the cold water inlet and a one way check valve at the hot water output, the bypass can be accomplished with one valve.

Example: clockwise bypass; counter clockwise normal use (or vice versa).

When the pointer is facing the cold water line (pointed to "you" like in the photo) the valve is in "normal"; when pointed "UP" it is supposed to be in bypass and a one way check valve in the upper hot water outlet prevents the bypassed water from entering the HW heater.

Just got off the phone with Willy.
Consensus is a bad valve.
The T valve is allowing flow to both the hot water heater and the bypass tube when it is in the "Normal" position (pointed to the cold water line).
When it is in the vertical position "Bypass" it works fine to isolate the hot water heater (thus he is getting the cold water).

He is going to drain the system tomorrow and examine the valve.

If it is broken, easiest fix IMO is to put a PEX straight valve in the bypass hose. If it is leaking, maybe it can be fixed.

He will let us know how he makes out.

Just goes to show that just when you think you have it all figured out; SOMEBODY has a camper that is totally different.

I had an Itasca motorhome with the same problem, turned out to be a backflow preventer valve on the hot water heater. The repairman said it was a common problem. My motorhome was about six years old when it happens.

Good Luck, Forrest

I think if replacing the valve doesn't work II will look into the backflow preventer valve on the heater.thanks

Do you have an outside shower? I seem to remember that years ago this problem was attributed to having the outside shower cold faucet open but the water flow was cut off at the shower head. The fix was to make sure the shower faucets were in the off position. I could be completely wrong here since my memory isn't what it used to be.

BTW, my 2004 Wildcat only had one shutoff valve too. My 2008 Wildcat had two shutoff valves and my new 2013 Silverback seems to have more shutoff valves than Carter has little liver pills. (Oops, showing my age here)

Was thinking about the check valve on the heater and I can't see how it could be "your" issue. If the valve is doing its job when properly positioned, no cold water should be bypassing it. The check valve at the top has to do with winterizing and keeping the antifreeze out of the HW tank when the valve is positioned to bypass the heater.

I think the valve (or the handle) has been misaligned inside the valve body. I think it is 90 degrees "out of phase." There should be a shaft with 3 holes in it. (picture a T on its side --| like this) When the holes are aligned --| the valve is in bypass (your handle is supposed to be toward the bypass hose). Then rotate the valve counter clockwise and the valve body should look like and the lever should point at the cold pipe:

bypass hose
cold __ hot
side | side
valve wall

Best I can do within the limits of the forum's posting software.
The hole pointing down will be blocked by the side of the valve wall and the water will flow straight through.

u have a 3 way valve. i have the same thing. with the body of the valve intack, unscrew the bonnet and pull the plug out and see if u can see the problem. sure sounds like it is bad.

on industral valves, u can adjust the bonet. if it has become loose, it may be allowing flow by it. i really doubt that this valve is that way but u may try seeing if the bonnet (cap part that the (stem) handle goes thru) is loose.
