I urge you to carefully read your tankless water heater manual before running pink stuff through that unit. I seem to remember that our Truma AquaGo Comfort said not to do so. Drain it, bypass it, and then, if you want to run pink stuff, do that after bypassing and ensuring it won't go through the Truma. We don't own that trailer anymore, but I seem to recall this, so please do check.

I think the conventional wisdom is to open the valve to drain your water heater, then leaving it open.

Bypass it to run your winterization fluid thru everything else, after you’ve run all the fluid thru and then some fresh water to flush things out in the spring or whenever, then open it back up.

Usually three days or so on the road flushing the toilet gets most of the pink stuff thru for me, but you can speed that up if you are not concerned about freezing.

Thanks. What you said seems correct. Just concerned if I just do the drain and bypass will all the water exit or is there a low spot that could freeze. I did read the manufacturers manual cover to cover with little help. I will call them to verify no water left in system. I appreciate everyone’s help. I always had a tank in my previous interstates and am new to a tankless one.

There should be sections in your owners manual, telling you exactly where lowpoint drains and the bypass valve are.

Agreed, I’ve read our old water heater are different than the new tankless models. Better double check the procedure on it. Getting ready to winterize and reviewing my notes. Seems so early .
