• Restores a proper, leak-resistant seal at the filter’s top air-relief port
• Compact design sits cleanly at the filter top without interfering with plumbing
• Direct swap into the same opening as the original 154687-style vent (verify in your parts list)

Description

The ARG ARP1547 Air Relief Valve is built to replace aging filter vents identified by OEM part number 154687. As air relief valves weather and wear, they become harder to turn, start seeping around the stem, or stop venting air cleanly. That leaves air pockets trapped in the filter tank, which makes the system noisy, unstable and less safe to open.

Dropping in ARP1547 restores a predictable bleed point at the top of the filter. On startup or after service, you open the valve, purge air until the water stream runs solid, then close it and allow the filter to run. It’s a small part that quickly eliminates hissing, weeping and stubborn vents without touching the rest of the equipment.

Pro Tip

Any time you’re doing a full cartridge or grid clean, look at the air relief. If it’s chalky, cracked or stiff, replace it now while the system is already down. Always shut off the pump and fully depressurize the filter before removing or installing any air relief valve—never assume the tank is safe just because the pump is off.
