BCD Maintenance Checklist: Essential Buoyancy Compensator Care and Service Schedule
A single equipment failure at depth can turn an incredible dive into a dangerous emergency—and most BCD malfunctions are completely preventable with proper care. In this episode, veteran diver Ray Hollister shares the exact maintenance routine that has kept his buoyancy compensator working flawlessly through more than 2,000 dives over four decades. Whether you dive a back-inflate wing or a traditional jacket-style BC, you'll learn the specific tasks, timing, and techniques that prevent stuck inflators, leaky bladders, and dump valves that refuse to work when you need them most.
Key Takeaways
- Your BCD needs internal rinsing, not just external. Salt water gets inside your bladder and forms a crusty layer on the walls—like the hard white buildup you see on a showerhead. You need to actually put fresh water inside the bladder, slosh it around, and drain it out through the dump valve after every dive day.
- The inflator button requires active flushing to stay reliable. Pressing your inflate button 8 to 10 times while holding the hose underwater pushes fresh water through the mechanism and washes out salt crystals before they make the button stick or move slowly.
- Dump valves need aggressive attention during rinsing. Sand and salt love to hide in the spring mechanisms of your dump valves, especially the rear one. Pulling each dump cord 5 or 6 times while water flows over it knocks loose particles that would otherwise jam the valve shut.
- UV light slowly destroys your BCD's fabric and straps. Leaving your gear in direct sunlight between dives causes the nylon webbing to weaken and eventually crumble—like how a rubber band gets brittle after sitting in a sunny window for months. Always dry in the shade.
- Multi-day dive trips demand a mid-week deep soak. When you're diving several times daily, salt builds up faster than quick rinses can handle. Submerging your entire BCD in fresh water for 30 to 45 minutes around day three or four dissolves hidden salt crystals that regular rinsing misses.
