Frequently Asked Questions

How many cartridges are in the Pentair 179136?

Four — the full set for one Clean & Clear Plus 520 filter. Replace all four together for even loading.

Which filter does the 179136 fit?

The Pentair Clean & Clear Plus CCP520 (filter model 160332) and the Waterway Crystal Water 525. For the 420 sq ft system, use the 179135.

What's the difference between 179136 and 179135?

Size and capacity. The 179136 cartridges are 130 sq ft each and about 32" long for the 520 system; the 179135 are 105 sq ft and about 26" long for the 420 system. They are not interchangeable.

How often should I replace them?

Inspect and clean every 4–6 weeks, and replace annually or when you see matted pleats, tears, or pressure that rises quickly after a cleaning.

Can I use aftermarket cartridges instead?

Aftermarket equivalents exist (Pleatco PCC130, Unicel C-7472), but this is the genuine Pentair OEM set, which guarantees the rated surface area and correct fitment on the manifold.

Should I replace all four at the same time?

Yes. Mixing new and old cartridges causes uneven loading, higher operating pressure, and shortened life on the new cartridges.
