Quick overview

  • O-ring included The valve arrives with its sealing o-ring, so you are not chasing a second part.
  • Used across the Hayward range Fitted to SwimClear, Star Clear, Star-Clear II, Star Clear Plus, ASL, Easy-Clear, Perflex, ReGenX and Pro-Grid filters.
  • Bleeds trapped air Opening it lets air out of the tank on startup so the filter fills properly and pressure reads true.

Product details

The Hayward ECX1322A is the manual air relief valve, supplied with its o-ring. It is the small bleed valve at the top of the filter that you open on startup to release trapped air.

Fitted across the Hayward range

Hayward uses the same relief valve on a large part of its filter line: the SwimClear cartridge filters, Star Clear, Star-Clear II and Star Clear Plus, the ASL and Microstar Clear filters, Easy-Clear, and on the DE side the Perflex range, ReGenX and Pro-Grid. That makes it a part worth keeping on the shelf if you look after several pools.

Why it matters

Air trapped in a filter tank keeps water from reaching the full filtering surface and makes the pressure gauge read something other than the truth. Bleeding it out at startup is basic practice, and the relief valve is the only way to do it.

The usual failure

The valve gets opened and closed constantly, so the stem and o-ring wear out before almost anything else on the filter head. The tell is a persistent drip or weep at the top of the tank that continues with the valve closed. Since the o-ring is included here, one part fixes it.

Questions and answers

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

Does the o-ring come with the valve?
Yes. This listing is the air relief valve supplied with its o-ring.
Will it fit my Hayward filter?
It is the standard Hayward manual air relief valve and is used across the SwimClear, Star Clear, Star-Clear II, Star Clear Plus, ASL, Easy-Clear, Perflex, ReGenX and Pro-Grid families. Check your filter diagram to confirm the position.
Is the part number ECX1322A or EC1322A?
The part number on this listing is ECX1322A. The source also shows it written as EC1322A in one place, which is the same valve.
Why is my filter dripping at the top?
Most often the air relief valve. The stem and o-ring wear with every bleed cycle, and once the seal is gone the valve weeps under pressure even when it is shut.
