A directional valve on the suction side of the water pump would be for winterization.
I actualy found that out last night. That was my first thought when I opened up that panel, but it looked like it ran somewhere. so I started wiggling it to follow it and see where it went and it popped up with a cap on it. so I guess I don't have to add that now haha
That was my guess too, but I can't tell if that is just a short section of hose to put into an antifreeze bottle or it went somewhere in the plumbing system?
ya I couldn't tell just by looking either, I had to physicly start trying to move stuff around. I think I got the worst PDI in history.
