My water heater has 3 valves on it. One on the red line at top = it's openOne in the middle = bypass valve closedOne on the blue line at bottom = closedShould the bottom blue line valve be open for normal RV usage?I'm just wondering, I am winterizing, drained water heater, shut off red line, opened bypass, blue already closed, will leave it that way. Is this correct?Thx!

If the blue line valve was closed you would not have gotten any hot water at the faucet, so it must have been in the open position.Normal RV operation:Red line valve openBypass valve closedBlue line valve openBypassed:Red line valve closedBypass valve openBlue line valve closed

If this is the type of setup you have with the blue line valve closed and still get hot water then that valve is defective.

1/4 turn valves....valve handle indicates if valve open or closedTraditional valve that you turn handle until fully open or closed....valve handle could end up any position

Thanks for the pictures, that is exactly what I have. Must be the valve then. Water heater works fine! Thanks!
