Dewinterizing 2020 Greyhawk 29mv

I just dewinterized my plumbing. It was my first time doing this. I flushed all faucets and shower heads several times to make sure all points ran clear from winterization fluid. When I went to switch the by pass valves on my water heater back to normal to fill the water heater I noticed that the valves were never turned to bi pass the water heater during the winterization process (done my an RV service center). I ran my water heater while testing out my propane during the dewinterization process (after flushing all lines) Has anyone experienced this and will it be a problem?

Not sure why RV dealer left it in that mode but I dont believe thats a problem as that wouldnt cause any damage since you did flush before using hot water heater. The main reason I believe you set the valves to bypass on heater is just to save on wasting 5 gals of RV Anti freeze in heater tank since the tank is drained at drain plug location.

The only thing i think you would want to do is open low point drains again and see if you get any antifreeze that could be trapped in water heater. Probably drain system completely one more time and make sure heater tank flushed out good.
