Product details

The Hayward CX2030Z3 is the air relief tube for SwimClear cartridge filters. It is the genuine Hayward part.

What it does

Water fills a cartridge tank from the bottom and air gets pushed to the top, where it sits above the water line as a pocket. The relief tube reaches up into that pocket so that opening the manual relief valve on the lid actually releases air rather than just water. Without it the tank runs with air trapped inside, which costs you filter area and can make the pressure gauge read oddly.

Check the model first

SwimClear covers a range of tank sizes and the source lists this tube against two overlapping sets of model numbers, so read the label on your filter and match it before ordering. It is a small part and easiest to fit while the tank is already apart for a cartridge clean.

Questions and answers

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

What does the air relief tube do?
Air collects in the top of a cartridge filter tank. The relief tube runs up inside the tank so that air can reach the manual relief valve on the lid and be bled off.
Which SwimClear filters does it fit?
The source lists it for the C2020, C2025, C3020, C3025, C4020, C4025, C5020, C5025 and C5520, and separately for the C2030, C3030, C4030, C5030 and C7030. Check your tank label against both lists before ordering.
Do I have to drain the filter to fit it?
You need the tank open, so it is a job to combine with a cartridge clean rather than something you do with the filter sealed and running.
Is it a genuine Hayward part?
Yes. It is Hayward OEM part CX2030Z3.
