Hi All,
Pool rookie here. Purchased the house with pool about 2 years ago. Last week I noticed the pool had DE all over the surface. My pool guy says the DE is returning to the pool because the filter (pentair FNS plus 48) is old and needs to be replaced. The filter was last cleaned by the pool guy in April and I didn't noticed any issues then. I searched the forum and found that torn and/or cracked grids or cracked manifold is typically the reason why DE returns to the pool.
So I took apart the filter (first time) and found no tears on any grids but the small grid is cracked and floppy. The 7 large grids have minor crushed ribs. Should all these grids be replaced anyway? The manifold has a crack that is not deep but can still be felt by dragging a fingernail over it. Should the manifold be replaced as well?
The retaining rod nuts were a bit rusty but turned ok. The bottom spider looked ok as well.
Based on online research, I'm guessing the filter was manufactured back in 2005. I spoke to leslie's pool supply and they said the entire filter should be replaced. I'd rather just replace the internal parts unless the filter is indeed on it's way out.
I've attached upclose pics of the manifold and small grid.
Another question, the DE powder on the filter was a light brown green color, with some layers being white grey. Is this normal for a filter that was cleaned back in April? Or is it just time for a cleaning? Pool load has been minimal since april.
any help is appreciated Thanks!
