Westend as you stated theres the cold water line on the bottom hot water on the top. each valve has 3 connection points. In, out and a piece of pex pipe that connects the 2 valves. The piece of pipe that connects the 2 valves looks like the by-pass but theres no valve on that piece of pipe. Is it possible that these 3 way valves are the by-pass??
Move each valve so it points toward the pex pipe. Undoubtedly, these two valves comprise the bypass system. There are a few different bypass configurations.
