    Angry Help? Pool stops circulating after awhile

    I am soooo frustrated, please help! I have had my pool for 2 years. It is a above ground 24' pool with a hayward sand filter. I have all my chemicals balanced perfect. And now my pump isnt working right. I can turn my pump on and it works perfect for 3 hours+- and then it stops sucking water into the skimmer or stops circulating water. There will be hardly any water circulation and very little water blowing out the return in the pool. But if i backwash it, then it will work perfect again for 3 hours and then stop again. I have no idea whats happening. I have already replaced the sand and oring on pump lid and the pressure stays the same, it doesn't go up or down? Any ideas?

    That is normal if you have algae, less common but not unheard of if you don't.

    Keep cleaning the filter, and clean up the water, until things get back to normal.

    Is the pump basket filling with air? Could you have a suction side air leak?
