    I would, it prevents a small amount of sand/stuff up in the valve, from the backwashing, from going back into the pool.

    By the way...go ISU :P

    How many psi does your pressure rise in a week? Or do you just routinely backwash?

    You only need to backwash when the pressure rises about 25% above the normal clean pressure. I wouldn't backwash every week unless it required it. And yes, you should rinse the filter a minute or two after a backwash.
