That regulator you're trusting with your life? Those fins that carry you through currents? Your BCD that keeps you neutrally buoyant? Every piece of dive equipment is an investment—in both money and safety. Yet many divers unknowingly destroy their gear through preventable maintenance mistakes, turning expensive equipment into premature replacements.
The math is simple: proper maintenance costs a fraction of replacement. The money you save by caring for your equipment correctly could fund an extra dive trip each year. More importantly, well-maintained gear is reliable gear—and underwater, reliability isn't optional.
Let's examine the ten most common maintenance mistakes divers make and how to avoid them.
Mistake #1: Rinsing Your Regulator While Pressing the Purge Button
The damage: This is perhaps the most expensive maintenance mistake in diving. Pressing the purge button while rinsing opens the second stage, allowing water to flow backward through the intermediate pressure hose and into your first stage. The first stage's internal components—precision valves, springs, and seals—are extremely sensitive to moisture and salt contamination.
Why divers do it: It seems logical to "flush" water through the system. Some divers do it accidentally while handling equipment.
The fix:
- Never press the purge button during rinsing
- Securely attach the dust cap before any contact with water
- Ensure the dust cap itself is completely dry before attaching
- Rinse under running tap water rather than soaking—this reduces the chance of water seeping past the dust cap
Mistake #2: Ignoring the Inside of Your BCD
The damage: Every dive, salt water enters your BCD through dump valves and the low-pressure inflator. This water contains salt, sediment, and potentially bacteria. Left unchecked, it corrodes internal components, breeds mold, and creates unpleasant odors. Eventually, the bladder material degrades from the inside out.
Why divers do it: Out of sight, out of mind. The exterior looks clean after a quick rinse.
The fix:
- After each dive day, flush fresh water into the bladder through the inflator hose
- Hold the deflate button while filling to allow water to enter easily
- Partially inflate the BCD and shake it vigorously to circulate water throughout
- Drain through all dump valves, one at a time
- Repeat until the water runs clear
- Store partially inflated in a cool, dry place
Mistake #3: Using Household Chemicals on Equipment
The damage: Bleach, household cleaners, alcohol-based products, and even some mouthwashes contain chemicals that attack rubber seals, degrade neoprene, and corrode metal components. The damage isn't always visible immediately but accelerates wear dramatically.
Why divers do it: These products work great on household items, so why not dive gear?
The fix:
- Use only products specifically designed for dive equipment
- For disinfection, use manufacturer-approved solutions
- Fresh water alone handles most cleaning needs
- For stubborn odors, use wetsuit-specific cleaners
- When in doubt, consult your equipment manufacturer
Mistake #4: Storing Wet Equipment
The damage: Mold, mildew, bacteria, and rust all thrive in damp environments. Wet storage causes wetsuits to develop permanent odors, metal components to corrode, and fabric to deteriorate. Zippers become stiff and eventually fail.
Why divers do it: After a dive day, energy is low and the temptation to "deal with it later" is strong.
The fix:
- Allow all equipment to dry completely before storage
- Hang wetsuits on wide, purpose-built hangers (never wire hangers)
- Store in well-ventilated areas away from direct sunlight
- Use silica gel packets in gear bags during extended storage
- Check stored equipment periodically for any moisture buildup
Mistake #5: Leaving Equipment in Direct Sunlight
The damage: Ultraviolet radiation is the silent killer of dive equipment. Neoprene becomes brittle and loses elasticity. Rubber seals crack and fail. Plastics fade, become brittle, and eventually break. Silicone mask skirts degrade and lose their seal.
Why divers do it: On dive boats, there's often nowhere else to put gear. After dives, equipment gets left on the dock or beach.
The fix:
- Store equipment under benches, in shade, or under towels when on boats
- Never leave gear on the beach or dock longer than necessary
- Dry equipment in shade, not in direct sun
- Store equipment in cool, dark locations long-term
- Consider UV-protective gear bags for travel
Mistake #6: Skipping Annual Servicing Because "It's Working Fine"
The damage: Regulator performance degrades gradually—so gradually that divers often don't notice until failure. Internal seals dry out, springs fatigue, and corrosion builds up. According to Divers Alert Network, approximately 11% of dive incidents are linked to equipment failure.
Why divers do it: Professional servicing costs money. If it's working, why fix it?
The fix:
- Service regulators annually or every 100 dives, whichever comes first
- BCDs should be serviced annually
- This applies even to equipment that's rarely used—sitting idle causes seal deterioration
- Build servicing costs into your annual dive budget
- Keep service records for warranty and resale purposes
Mistake #7: Improper Wetsuit Storage
The damage: Wire hangers crease and permanently deform neoprene. Folding creates cracks and stress points. Stacking heavy items on top compresses the neoprene, reducing its insulation properties.
Why divers do it: Wetsuits are bulky, and storage space is often limited.
The fix:
- Invest in wide, padded wetsuit hangers
- Hang wetsuits folded at the waist over a wide hanger rod
- For long-term storage or transport, roll rather than fold
- Never stack items on top of stored wetsuits
- Lubricate zippers with appropriate zipper wax periodically
Mistake #8: Neglecting Hose Protectors and Connections
The damage: Salt crystals accumulate under hose protectors and at connection points. These hidden deposits cause corrosion and eventually lead to leaks at the worst possible times.
Why divers do it: These areas are hard to see and easy to overlook during quick rinses.
The fix:
- Slide hose protectors back during rinsing to clean beneath them
- Work connection points back and forth under running water
- Periodically remove hose protectors completely for thorough cleaning
- Inspect connections for any signs of corrosion or wear
Mistake #9: Improper Camera and Housing Care
The damage: Underwater photography equipment requires even more meticulous care than dive gear. O-ring failures cause floods. Salt crystals on electrical contacts cause connection failures. Sand in moving parts destroys mechanisms.
Why divers do it: After an exciting dive, the focus is on reviewing images, not cleaning equipment.
The fix:
- Soak housings in fresh water before opening
- Always open housings in clean, dry environments
- Clean and lightly grease O-rings regularly (following manufacturer recommendations)
- Inspect O-rings for hair, sand, or damage before every dive
- Store with O-rings slightly greased and housing open to prevent seal compression
Modern smartphone underwater housings like the DIVEVOLK SeaTouch 4 Max simplify this process with fewer complex parts mean fewer failure points and easier care.
Mistake #10: Using Compressed Air to Dry Equipment
The damage: Compressed air from tanks isn't pure—it can contain moisture, oil residue, and contaminants. Using it to blow dry equipment forces these contaminants into mechanisms and can push water deeper into components rather than removing it.
Why divers do it: It's conveniently available and seems like an efficient drying method.
The fix:
- Air dry equipment naturally in ventilated, shaded areas
- Use clean, dry cloths for initial moisture removal
- If compressed air is necessary, use only clean, filtered air sources
- Never force air into sealed components
Building a Maintenance Routine That Works
Good maintenance doesn't have to be time-consuming. Here's a practical routine:
After Every Dive Day
- Thorough fresh water rinse of all equipment
- BCD internal flush
- Visual inspection for damage
After Every Trip
- Complete drying before storage
- Lubricate wetsuit zippers
- Inspect O-rings on housings and cameras
- Check for any developing issues
Annually
- Professional regulator service
- BCD service and inspection
- Review all equipment for wear and replacement needs
The Real Cost of Poor Maintenance
Consider the numbers:
- A quality regulator set: $800-$1,500
- A good BCD: $400-$800
- A wetsuit: $200-$500
- Annual professional servicing: $150-$250
Equipment that's properly maintained can last 10-15 years or more. Neglected equipment often needs replacement in 3-5 years. The maintenance cost of $250/year is trivial compared to replacing a full equipment package every few years.
That savings alone could fund a dedicated dive trip. The choice is clear: spend a little time on maintenance now, or spend a lot more money later.
Investing in Quality Pays Off
Quality equipment that's well-designed for maintenance makes your job easier. When choosing underwater photography gear, for example, the DIVEVOLK housing systems are designed with maintenance simplicity in mind—fewer complex parts mean fewer failure points and easier care.
Pair quality equipment with proper maintenance habits, and your gear will reward you with years of reliable service. The ocean is challenging enough without adding preventable equipment failures to the equation.
