This specialized tube is crafted from a durable, chemical-resistant polymer designed to withstand constant immersion in treated pool water without warping or degrading. Its primary function is to bridge the gap within the filter manifold or head assembly, ensuring that any air pockets formed during pump operation are channeled directly toward the manual air relief valve for evacuation. By maintaining a water-filled environment inside the filter, this component helps prevent air-related surging in the plumbing lines and ensures that the entire surface area of the filter element remains effective for debris removal.
