Customer-Facing Q&A

What filter does the Pentair 178582 lid fit?

The Pentair 178582 lid assembly fits the Clean & Clear Plus 520 sq. ft. cartridge filter and is also commonly listed for the Quad D.E. 100 filter.

Is this a complete filter?

No. This is the replacement upper tank lid assembly only. It is not a complete filter, lower tank, cartridge set, clamp assembly, manifold, or internal grid/cartridge assembly.

Does this include the air relief valve or pressure gauge?

No. This lid is commonly listed as not including the air relief valve or PSI pressure gauge. Those parts may need to be transferred from the old lid or purchased separately.

What color is the lid?

This lid is commonly listed in Pentair’s almond/tan color.

Will this fit a Clean & Clear Plus 420?

No. This listing is for the Clean & Clear Plus 520 sq. ft. model. Other filter sizes use different tank lid parts.

Can this be used on a saltwater pool?

Yes, this filter lid is used on compatible pool filtration systems and may be used with properly maintained saltwater pools. Always maintain water chemistry within manufacturer guidelines.

Should this be professionally installed?

Professional installation is recommended. Pool filter tanks operate under pressure, and the lid, clamp, O-ring, air relief assembly, and pressure gauge must be installed and inspected correctly before operation.
