HIGH FLOW MANUAL AIR RELIEF VALVE: Designed to efficiently release trapped air from pool and spa filter tanks, helping restore proper water circulation, stabilize system pressure, and support safe startup after maintenance or filter cleaning.
UNIVERSAL POOL & SPA FILTER COMPATIBILITY: Engineered as a universal replacement air relief and bleeder valve for pool and spa filters that use this common vent valve design, including many cartridge and D.E. filtration systems.
DURABLE CORROSION-RESISTANT CONSTRUCTION: Manufactured using high-strength plastic and metal components to withstand pool chemicals, moisture exposure, and repeated pressure venting cycles for long-lasting performance.
CONTROLLED PRESSURE RELEASE DESIGN: Provides smooth, controlled venting of trapped air without excessive water spray, helping prevent pressure spikes, reduce stress on filter components, and extend system lifespan.
EASY INSTALLATION & MAINTENANCE: Features a threaded body for quick hand-tight installation and simple manual operation, making it ideal for routine servicing, system priming, and seasonal startup.
