What is the open/closed position on the two aft low-point drain
Can anyone please explain the open / closed position for the two aft drains on a Jayco Swift 185 SLX. The valves are designed as in-line valves, but are plumbed to the two main lines via a very short nipple.
I've tried every conceivable position without getting any water to drain from these two aft low-point drains. The photos are upside down. Sorry, I can't figure out to right-end the photos.
This newbie appreciates your enlightenment.
