3 valves. Cold water in, hot water out. Between those two lines is the bypass. Cold water in and hot out the valves should be "inline" with the lines. Bypass should be "cross" the line. Just the opposite when you want to winterize. Do a forum search, there are several good pics that people have posted if unclear.
