Hi,
I posted this issue several days ago and didnt receive a lot of help so Im posting again.
Im getting DE shot into my pool WHILE the pump is running. The pool and all of the equipment is 3 years old. Pentair FNS Plus 48 filter. Inground vinyl liner.
This is what Ive done to troubleshoot:
To vacuum up the DE, Ive been using a combination of the pool bot, vacuum to filter, and vacuum to waste (this is tough because I lose so much water so fast when I do so).
If anyone has any other ideas...
Im about to drop $100-150 on all new grids plus $90 for a new manifold just to be sure that it isn't the grids or manifold. And if replacing all the grids and manifold doesnt fix it...Im literally at a loss and scared that the issue may be under ground or something.

Im getting DE shot into my pool WHILE the pump is running. The pool and all of the equipment is 3 years old. Pentair FNS Plus 48 filter. Inground vinyl liner.
This is what Ive done to troubleshoot:
- Pulled out and inspected each individual grid. There was one grid with a cracked rib that I replaced with a new grid. I looked at all ends, corners, both sides of all grids. I did not see any rips or tears.
- Pulled out the manifold and inspected for cracks/hair line cracks.
- Replaced the Standup Pipe o-ring and added lube.
- Brought the filter grids and manifold to two pool stores for additional 'well trained' eyes. Three pool store guys inspected them. They said my grids look near perfect. One guy said that the grids (pentair) looked like they might have been glued together at the seams on the bottom in addition to being sewn together. The glue in spots is being undone, but it is still sewen together. One guy said that the manifold has a tiny hairline crack but it doesnt go all the way through and looks good.
- Replaced the air bleeder tube that plugs into the top of the manifold.
- Lubed up the filter waiste band o-ring and removed debris for a much better seal.
- Lubed up the pump basket o-ring for a much better seal.
- Ensured that the manifold is snug on the standup pipe as well as on the grids themselves covering the cloth (even tried to pull the cloth up the center plastic spine piece that goes into the manifold).
- Cleaned up the filter completely (even the bottom manifold that everything sits on). The filter and its elements were spotless.
- Unscrewed the Multiport Valve. Spider gasket looked good.
- Checked all chems via taylor test kit, all good.
