This year when I opened my pool (Sat the 20th), there was a split in the manifold of my FNS Plus filter. Consequently all of the DE I put into the filter blew back into the pool. I think I made an additional backwash and reload of DE, so probably a total of around 3 pounds, before I realized.
I bought a new manifold and installed it and carefully checking all of the fins for holes etc before replacing the cartridge. (I bought new fins last year, so they are in good condition).
My water is cloudy and milky. When I can see the bottom, there is a thin layer of DE. I can brush this up into clouds.
I've been trying to correct this by putting more DE in and brushing the pool. Does not seem to work.
Not putting DE and brushing the pool.
Backwashing frequently in both cases.
When I backwash, the pressure gauge is at about 15 or so and there is a good flow coming from the jets.
Then, literally while I stand there over a period of about 1-2 mins, I can watch the gauge go up to about 30 and the flow reduce to almost nothing.
I can then go and backwash just for about 20 seconds and that the pressure is back to 15 and the flow good. Then the process repeats in a minute or two.
No idea what to do here!!
I feel good about the new manifold and its installation. Looks pretty tight.
Any ideas? Please?
Thanks in advance
