VENT TUBE KIT

This vent‑tube kit is intended to provide a dedicated passage for air (or trapped gases) inside the filter/tank to escape safely, helping to prevent air locks or pressure imbalances that can impair filter performance. When water and debris flow through the filter media, air can accumulate in pockets — especially after filling, maintenance, or backwashing — and without a vent path, that trapped air can reduce water flow, cause uneven filtration, or even stress components under pressure. The vent tube gives a controlled, low‑restriction route for that air to leave the system (often via the air‑relief valve at startup), allowing the tank to fully fill with water and operate as designed. Because it’s a genuine part, it’s built from materials compatible with pool water, chemicals, and pressure conditions — important for long‑term reliability of the filtration system.
