Filter and Pump working together?

[BrandonJamesD]

I recently purchased a new home with an in ground pool. We opened the pool last year and couldn’t get it clear for the life of us. We balanced our chemicals; there are no tears in the liner, which means…It’s most likely an issue with the pump/filter.

Hayward Super Pump
Model: C48K2N143B1 (SP-1607-Z1-M)
Horsepower: 1 HP
KW: .75
Volts: 115/230
Amps: 15.0/7.5
HZ: 60
SF: 1.1
PH: 1
FR: 56J
RPM: 3450

Filter (sand changed last season, no breaks in any portions of the filter)
Hayward Pro Series High Rate Sand Filter
Model: S210T
Effective Filtration Area: 2.2
Filtration Rate GPM/FT: 20
Filtration and Backwash Design Flow Rate GPM: 44
Max working pressure: 40 PSI
Amount of Media: 200lbs

My Plumbing:
1 ½ Inch hard plumbing, all level with the inlets and skimmer, 24” rise from pump to top of the filter. There is 1 skimmer and 2 return jets. The skimmer runs to the pump, which runs to the filter, coming out of the filter is 1 solid line, breaks into 2 lines for the 2 returns.

Operation:
My operating PSI is about 15-20psi. The water is cloudy, when I vacuum the pool (all the junk at the bottom) the filter seems to be passing the junk through the sand, breaking it up into smaller pieces and returning to back to the pool. I ran the pool for 12-14 hours a day last year, and to no prevail. It remained cloudy the entire time. When I gave up in late august and turned the pump off, the water began to clear up a bit….


Any suggestions?

If you can see the returns in the pool, you can test the filter. Buy a small box of DE at a pool store (don't let 'em sell you anything else) and add a half Cup to a Cup to the skimmer and watch the returns. If DE comes out, there's a problem with the filter. Watch the filter pressure, a sand filter with DE will build pressure quickly. Take a look at this thread: http://pool9.net/de-test/ (http://pool9.net/de-test/), it discusses using DE in a sand filter.
