Bad pump or filters?

I am not convinced that the filter is
the problem yet but not sure how to troubleshoot
the problem.
==================
Take the sprinkle or spray head off the pump and let it run. See if it
still slows down. Are you cleaning the slime from the spray-head? Could
that be getting clogged from what passes through the filterpad? Have you
checked for excessive slime in the impeller well? Pull the impeller out and
clean it and the well. If it doesn't have a free impeller gently grasp the
fins and pull gently up a little on them. The impeller may have worked
it's
way "down" and is binding. I have one pump that does that a few times over
the summer.
