Match this valve to your filter by part number, not just appearance. If your parts diagram or existing vent calls out 154689, ARP1549 is the intended replacement style. When you replace the air relief, it is also a good time to look at the pressure gauge and tank clamp O-ring so the entire filter assembly seals and vents correctly.

Q: How do I confirm this is the right valve?
A: Check your filter’s parts list or the stamping on the existing vent. If it specifies air relief 154689, ARP1549 is the matching replacement.
Q: Do I need to drain the filter to change the air relief?
A: You must fully relieve pressure before removal; expect some water in the tank and minor spillage. Follow the filter manufacturer’s service instructions.
Q: My system still pulls air after replacing the valve—why?
A: A new air relief fixes venting and sealing at the filter top. Ongoing air in the system usually points to suction-side leaks, low water level, or pump issues that need separate troubleshooting.

ARG Air Relief Valve Replaces 154689 | ARP1549
ARG ARP1549 air relief valve replacing OEM 154689. Manual filter vent bleeds trapped air and restores a clean top seal. SKU ARP1549.
Features

- Manual vent allows trapped air to be bled from the filter tank on startup
- Helps quiet the system and reduce air hammer and pressure surging
- Restores a proper, leak-resistant seal at the filter’s top air-relief port
- Compact design stays clear of nearby plumbing and equipment
- Direct swap into the same opening as the original 154689-style vent
Description
The ARG ARP1549 Air Relief Valve is built to replace aging filter vents identified by OEM part number 154689. As these valves weather and wear, they can become hard to turn, seep around the stem, or stop venting air cleanly. That leaves air pockets trapped in the filter, which makes the system noisy, unstable, and less safe to open.
Dropping in ARP1549 restores a predictable bleed point at the top of the filter tank. During startup or after service, you open the valve to purge air until you see a solid stream of water, then close it and let the filter run. It’s a simple swap that gets rid of hissing, weeping, and stubborn vents without touching the rest of the equipment.
Pro Tip
Plan on changing the air relief whenever you’re already doing a full filter clean and the existing valve looks sun-baked or crusty. It’s much easier to replace the vent while the system is down than to come back later chasing a small leak or air issue. Always fully depressurize the system before you remove or install any air relief valve.
