Bypass Valves on ACE 30.4

Anyone find the water heater bypass valves on ACE 30.4?

Picking mine up Saturday. Headed south for a week or so to check out. Will fill fresh when I get to Death Valley and will have to winterize when heading back to Idaho. Found the drains and pump suction feed line for antifreeze.

Not sure how to get to bypass valves. Looks like they are behind screwed in grate below fridge. I hate it when the dopey designers do they that. They obviously never owned an RV. I have to winterize several times each year. When at home I blow out the system and just put a little antifreeze in the pump.

They are located behind (inside the coach) the Water heater. you may need to unscrew a panel.

We just picked our 30.4 up 2 months ago.
Our bypass valves are under the master bed.
Remove the bottom right drawer at the foot of the bed a d they are right behind it
