I just finished the annual winterization ritual. I had a water heater bypass kit installed last spring and I'm wondering: 1) was it installed properly and should there be a shut off valve installed on the heater's inlet line; 2) do I have the valves set properly; and 3) is this why I now have hot water coming out of cold water taps? The vertical picture shows the bypass kit -- the city water connection is at the top. The horizontal pic shows the valves set for winterization (correctly I hope).
Thanks!
