ARG ARP2730 air relief valve replacing OEM 273550. Manual filter vent bleeds trapped air and restores a clean top-port seal.

Features

• Replacement air relief valve for filters that originally used OEM part 273550
• 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 sits cleanly at the filter top without interfering with plumbing
• Direct swap into the same opening as the original 273550-style vent (verify in your parts list)

Description

The ARG ARP2730 Air Relief Valve is built to replace aging filter vents identified by OEM part number 273550. As air relief valves weather and wear, they can become stiff to turn, start seeping around the stem, or stop venting air cleanly. Air pockets trapped in the filter tank make the system noisy, unstable and less safe to open.

Dropping in ARP2730 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 normally. It’s a quick, low-cost way to get rid of hissing, weeping and stubborn vents without touching the rest of the equipment.

Pro Tip

Any time you do a full cartridge or grid clean, inspect the air relief. If it’s chalky, cracked or hard to operate, 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.
