    While vacuuming I see dirt returning to pool?

    While I am in the process of trying to clean my pool, I am running the navigator to vacuum some and while doing so, there is dirt/debris going straight back into the pool via the returns, what could be the problem? I just today replace the spider gasket thinking maybe thats the culprit. Now Ima draining the sand filter so I can look at the sand, but draining the water from the sand filter is a slow go. What should I be a looking fer as far as the sand goes???

    Low sand level or sand that wants to retain its shape and not lay naturally would be the most common things. The latter can result in channels that the water can use to bypass the sand.

    Thing is I am not exactly sure how much sand it holds and for that matter how much is in the filter, can I buy some and put new over old???
