rockwood bypass

Hello all, I purchased a 2019 2906rs in nov.and it was already winterized. When I attempted to dewinterize I cant find the by pass. I can see the inlet and outlet valves coming from the water heater to turn on, but I'm not sure about the bypass valve. their is a valve that comes from the connection marked winterize. Just not sure. Thanks in advance

The valve you found called winterize is the one you will use allow the water pump to draw in antifreeze when you winterize. Some WH only have 2 valves and a backflow valve while others have three valves.

Photo 1 is winterization valve.
Photo 2 is in winterized position need to change for summer use.
Photo 3 is in winterized position all three need to be switched for summer use.

There are a number of ways in which they've figured out how to plumb the water heater valves. See attached for 6 or 7.

Here's a pic of the bypass valve on my Flagstaff (sister brand to the Rockwood - same trialer, different interior colors and graphics). So there is a good chance yours has the same plumbing setup.
Not sure which direction is to suck anti-freeze. My water heater valves match Flybob's bottom pic.

thank you all for help. Was extremely aggravated with Camping World of hanover where I purchased in October. Called them on sat and just asked for someone from service to walk me thru since it was different than my previous tt. The woman told me they were too busy and referred me to rvdoctor.com or "search utube". Today I reached out to FR and they actually emailed me a step by step. Thanks again everyone

They should have given you a full walk-through before you ever left their lot. Shame on them!

Picked mine up in November from same dealer. They would not let me hook up to water to test plumbing and insisted everything had been tested and then winterized. Flushed plumbing this week for first time and guess what? Not a drop of pink stuff. Thinking I lucked out since nothing seems to be leaking, though I have yet to test the water pump and fresh water tank.

There's probably never been any water in your system. MAAAAYBE they did an air pressure test, but I'd be skeptical.
