Product details

CX3020DA is the Hayward top closure plate for the C3020 and C4020 cartridge filters. It is the genuine Hayward part, the same plate the filter was built with.

What it does

The closure plate caps the cartridge assembly inside the tank. It has to sit flat and seal so that every drop of water leaving the filter has passed through an element. A plate that has cracked, split or warped lets water take the short route around the cartridges, which shows up as a pool that will not clear no matter how clean the elements are.

Ordering

This listing is the closure plate alone. Cartridges, o-rings and clamp hardware are separate parts, so if the filter is coming apart anyway it is worth pricing those at the same time.

Questions and answers

What people ask about this product, answered by our pool techs.

Which filters is this for?
Hayward lists CX3020DA as the top closure plate for the C3020 and C4020 cartridge filters.
Is this a genuine Hayward part?
Yes. It is the Hayward OEM part, number CX3020DA.
Does the cartridge come with it?
No. This is the closure plate on its own. Filter elements are ordered separately.
How do I know mine needs replacing?
Look for cracks, splits or a warped face when the tank is open. A plate that no longer seats squarely lets unfiltered water past the elements.
