I made another thread bc I thought this maybe a separate thing but you can delete if that was incorrect.Lets take a close look at your filter/pump. First some questions to help me dial it all in.........Did you put the filter on rinse BEFORE you the pump/filter?
Sand-while adding the sand did you use care to make sure none of it got in the center pipe? Did you hand add the first of the sand to make sure it did not plop on the laterals and damage them?
That is called the Pump Basket or at least that is what I call it as it is the basket right in front of the pump so......pump basket. Did you add any o-ring lube to the o-ring in the lid?
This should get us started!
So I am pretty sure we did the rinse/backwash bc I read your instructions about how to do it that you gave in another thread about letting it run clear. We may have had the dial on "backwash" though.
Center pipe, there was a cover that we put over it so that didn't happen. My husband and handyman just poured it out of the bag. Doh! But have the bottom piece completely out and cleaned and nothing is cracked on the bottom. All the pieces look new still.
O-ring is there and they did not put any lube on it.
So we are about to put everything back together. But it was 3 inches below the minimum line when we took it apart. Also going to level the platform everything sits on to see if that helps.
