I don't know if the picture will show so I will describe. I don't know if my 2019 Wildwood has a bypass valve on the hot water heater. There are two valves. One on the cold line and one on...
I agree with Grandpa. Those are 3-way valves or they wouldn't have three ports for the plumbing. Turning the valves will close off to tank and open the bypass (blue line).
