Maintenance Tips
-
Rinse the first and second stages with fresh water after use to remove salt, sand and chlorine. Avoid fully submerging the regulator and don’t depress the purge during rinsing to prevent water entering low‑pressure internal parts.
-
After rinsing, shake or gently blow out excess water from the second stage before drying.
Drying & Storage
-
Allow the regulator to air dry in a cool, shaded area with the mouthpiece/hose free of water buildup.
-
Store in a padded bag or case, away from direct sunlight, heat and humidity, and never under pressure (disconnect from tank).
Inspect Components
-
Periodically inspect hoses, O‑rings, connections and mouthpiece for cracks, wear or kinks; replace worn parts promptly.
-
Listen for air leaks by attaching the regulator to a tank and monitoring for hissing.
