Hot water heater

We just bought a 2019 23 rbhl. I was looking at the valves on the back of the hot water heater and Iím having a hard time figuring out where the valve need to be to bypass the water heater and where they should be to flow into the heater. Rv we had before had three valves and I knew which went where. The new one has only two. I went on line to the owners manual but it only addresses the three valve system. Any help would be greatly appreciated.

I think they have it plumbed wrong. They have hot and cold mixing. Contact the dealer.

No problem. the valve handle is how you set which line the flow goes to.



Looking at your pic, although I can"t really see the handle at the top red line coming out of the water heater, the handle appears to be in line with the line coming out of the tank. This is how you want it for normal use.

However, it appears the handle on the bottom blue line is parallel with the line AND the white bypass line. This will have the water heater inlet shut off, and is not how you want it for normal use. You need to turn that handle 90 degrees to be in parallel with the blue line entering the water heater. It (blue line) will then match the position of the top handle (red line)

Just imagine, for a moment, if there were no hypothetical situations.

The valve on top and bottom turn so that they either turn toward the hot water heater or turn toward the hot line on top or toward the blue line on the bottom. If I understand you correctly then the one on top should be turned toward the hot water heater and the one on the bottom should be turned toward the blue line.

You want BOTH valves turned towards the heater tank, for normal use.

Your bottom one needs to be turned. Leave the top one as is.

Thank you. I understand now. So when it comes time to winterize, I guess both valves will be turned toward the red line and the blue line instead of toward the heater.

Exactly, which will allow water from the cold blue line into the white bypass line...then from the white bypass line into the red hot water line. This way you can pump antifreeze into the cold blue lines and it will be able to get into the red hot lines.

No water can enter the water heater tank as the valves will have the inlet and outlet ports closed off once you turn them....thus bypassing the tank.

Easy Peasy
