Gray water tank emptying slow

webers3

The black water tank on my 320s empties quickly, matter of seconds but the gray water is rather slow, not a trickle but not as quick as black water. It may take 2-3 minutes to empty a half full gray water tank. Are others experiencing the same or do you think there may be some blockage?

The gray tank is larger and has a smaller drain, so yes it takes longer.

As N7SHG said, the gray tank outlet is smaller than the black, so slower to drain.

Are you sure you are opening the gate valve all the way? Sometimes they havea  sticky spot.

I had the opposite problem a couple years ago. I thought my valve was leaking but it turned out it just needed a little extra push to close it all the way.
