Hey everyone...got a question about DE Filter grids. I have been real busy so I had the company that built my pool (Pulliam Pools) come out and clean my filter grids and take care of a few other warranty type items this week. Pulliam does an outstanding job and I have complete faith in their judgement. My pool is 2 years old and I backwash normally when I should. When they took apart my filter they indicated I needed to replace the grids as they were starting to get holes in them. I was somewhat surprised since the grids are only two years old. With that said, we had a very bad dust storm, which is rare for North Central Texas, about 6 weeks ago which deposited a lot of dirt in my pool. Of course I backwashed a few times after the storm as the pressure was going up (but only about 3 or 4 psi) till the pool was clean. Anyway, how long should the grids last? It cost me a few hundred bucks to replace them. Do you think the dust storm caused the damage? I have never let my pressure get more than 6 or 7 psi higher than normal since we built the pool. I guess I was hoping to get longer usage of the grids.
