I apologize about my wording the bypas s is closed to allow hot water to flow.... It's a one valve bypass.
Where would I look at the check valve at?
All other faucets seems fine no leaks and not turned on. In and out...
If you have the one valve bypass, the check valve is at the tank outlet. Mine is the top line on the tank and OEM was white plastic one screw directly into the tank bung. In this picture I found on the web you see a white check valve on the hot line.
When my check valve failed it would slam shut the wrong direction and we had no hot water.

Here is another picture with a brass check valve. I believe this bypass valve is in the bypass position. Only a check valve is in the outlet to prevent water to enter the tank when in bypass mode. Chris
