Try running it with the 3pth in the lowered position. Might be stealing too much flow form the rest of the system. You might be as well off to just get the rockshaft valve looked at. If your screen is plugged, which sounds unlikely, you might be looking at a brake job. There is a chance as well that the flow control under the dash is hanging up.
