Product details

The Hayward CX3000Z3 is the air relief tube assembly used inside Hayward cartridge filter heads. It is the genuine Hayward part.

What it does

Air collects at the very top of a filter tank, above the water line and above the ports. The relief tube runs from the relief valve down into that space so the air has somewhere to go when you open the valve. It is a small piece of plastic doing a job you only notice when it stops working: the valve opens, water comes out, and the tank still holds air.

Check your model

This tube is shown in the parts diagrams for the Super Star Clear C-2000 through C-5500 series and for the SwimClear cartridge filters. It is also carried under the Star Clear Plus and Star Clear II families. Filter heads changed across those generations, so read the model number off your tank label and match it against the diagram for your filter before you order.

Questions and answers

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

Which Hayward filters use this tube?
It appears in the parts diagrams for the Super Star Clear C-2000 through C-5500 and the SwimClear cartridge filters. It is also listed under the Star Clear Plus and Star Clear II families, so match your model number against the filter head before ordering.
What does the air relief tube do?
It reaches up into the highest point of the filter tank so that air collecting there has a path to the relief valve. Without it, opening the valve vents the space near the valve only and the trapped air stays in the tank.
Is this a genuine Hayward part?
Yes. It is Hayward part CX3000Z3.
My filter will not bleed air. Is this why?
It is worth checking. If the relief valve opens freely but no air comes out and the pressure gauge stays high, a broken, cracked or missing relief tube is a common cause.
