Pentair Air Relief Tee Valve

The Pentair Air Relief Tee Valve (part number 273062) is a specialized internal and external air-management plumbing fitting engineered for Pentair Triton and Triton II side-mount fiberglass pool and spa sand filters. Injection-molded from a heavy-duty, high-impact PVC composite, this three-way T-shaped valve assembly connects directly into the upper plumbing manifold and air relief tube line near the top access dome of the filter tank. Its primary functional role is to facilitate the manual or automated venting of compressed air pockets that naturally accumulate at the high point of the pressurized filter shell during pump startup, ensuring a smooth, completely flooded hydraulic flow and protecting the tank from dangerous pressure surges. Built to withstand continuous internal hydraulic operating pressures up to 50 PSI, turbulent water movement, and prolonged exposure to highly concentrated pool chemicals like chlorine and acid, this durable valve assembly prevents external weeping and maintains system safety. Because it features a compact, thick-walled plastic configuration without heavy metal gauges, this individual air relief tee valve carries a product and shipping weight of approximately 0.30 pounds (about 4.8 ounces).
