What to do if your backwash valve gets stuck?
With the pump off, all of the pressure in the filter should go away within a second or two. Often enough those valves get stiff and just need more force. Occasionally an O-ring gets stuck on the edge of one of the pipe openings and pulling too hard can tear it. In those cases rocking up an down can often clear it.
Why does my Superflo pool filter not backwash?

What happens when you press down on a valve handle?
When you press down on the valve handle to change positions of the valve, you are compressing the spring. If the valve spring becomes broken, which can happen from chemical corrosion, the handle will be floppy (no tension) and you may experience a problem of water (and debris) making it’s way into different ports or coming out of the backwash port.
What should I do if my pool filter won’t backwash?
Normally, I very quickly go from filter, then pump off, then valve to backwash, then pump on, and I get backwash flow within seconds. However, when I went to backwash it, it took a very long time to prime to backwash (I have a Pentair Sand Dollar filter). And then after the backwash, I waited for 10 minutes to rinse but it never flowed to rinsed.
