I'm on day 10 of my SLAM process and the pump has been running 24/7 during that time. Over the last couple days I've noticed the pool level dropping slightly and noticed a big wet spot where my discharge/backwash hose is connected. I removed the hose and there is a steady stream of water coming out of the line, and this is while the valve is on the filter setting. What could be causing this?

If you have a multiport valve, you have a bad spider gasket. If your backwash valve is just up-down, you have a bad O-ring.
It's a Pentair multiport. The only number I see on top of the valve is 27-1140 and there are two stickers on the side of the valve that have faded out over the years. Google showed nothing for that model number. Are the spider gaskets universal given the same company and diameter? It doesn't look that hard to change out.
I don't know, but I'll bump your post up and hope someone who does sees it.
That is the part number for the instruction label on a 1.5" sand filter PacFab HiFlow valve.
