Regular equipment servicing is essential to ensure that your gear is functioning correctly and safely. Properly maintained equipment not only enhances your overall diving experience but also significantly reduces the risk of malfunctions that could lead to accidents or death. This guide covers the importance of servicing your dive gear, the recommended service intervals, and tips on maintaining your equipment.
Why regular equipment servicing is essential
1. Ensures reliability underwater
Diving requires complete trust in your gear, from your regulator to your buoyancy compensator device (BCD). Regular servicing helps ensure that every piece of equipment will work as expected when you are underwater. A well-serviced regulator will provide consistent airflow, while a properly maintained BCD will keep your buoyancy under control.
2. Prevents malfunctions and emergencies
Dive equipment is exposed to saltwater, sand, and significant pressure changes. Over time, wear and tear can lead to issues such as leaks, corrosion, or mechanical failures. Regular servicing helps identify and resolve these issues before they cause problems during a dive.
3. Extends equipment lifespan
Quality dive equipment is an investment. Regular maintenance extends the lifespan of your gear, ensuring that you get the best return on your investment while staying safe.
Recommended servicing intervals
All dive equipment should be serviced at least once per year, or according to manufacturer recommendations, and before any dive trip after a prolonged break.
1. Regulator
- Recommended Servicing Interval: Annually or every 100 dives, whichever comes first. Also if there are signs of reduced performance.
- Service Overview: During servicing, the technician will disassemble, clean, and inspect all components of the regulator. O-rings, filters, and other critical parts are replaced, and the regulator is reassembled and tested for proper function.
2. Buoyancy Compensator Device (BCD)
- Recommended Servicing Interval: Annually.
- Service Overview: The BCD is inspected for leaks, damage to the bladder, and functionality of valves and inflator mechanisms. Any worn parts are replaced, and the BCD is tested to ensure it holds air properly and that all straps are secure.
3. Dive Computer
- Recommended Servicing Interval: Battery replacement every 1-2 years or as indicated by the manufacturer or the device.
- Service Overview: Batteries are replaced, and the computer is tested to ensure accurate depth and time readings. The technician will also inspect the seals to maintain water resistance.
4. Dive Cylinder
- Recommended Servicing Interval: Visual inspection annually, with a hydrostatic test at least every two years.
- Service Overview: Visual inspections check for corrosion, cracks, or other damage. Hydrostatic tests measure the cylinder’s ability to handle pressure, ensuring it remains safe for use.
- Important: In August 2017, some older aluminium cylinders were deemed unsafe and removed from service by Worksafe due to the alloy used. These cylinders cannot be safely tested and should be removed from use immediately.
5. Dive mask, fins, and snorkel
- Recommended Servicing Interval: Regular self-inspections before each dive.
- Service Overview: Inspect your mask for cracks or tears in the skirt, check fin straps for wear, and ensure the snorkel is clear of debris. These items are usually low-maintenance, but small issues can still impact your dive.
Signs your gear needs servicing
1. Poor regulator performance
If you notice increased resistance when breathing through your regulator, uncontrollable or excessive airflow or hear unusual sounds, it is time for servicing. These are indications that something is wrong with the internal components and should be addressed before your next dive.
2. Slow or inconsistent BCD inflation
If your BCD is slow to inflate or does not hold air properly, it is time to have it serviced. A faulty BCD could put you at risk of drowning during your dive by making buoyancy control difficult.
3. Battery warnings on dive computer
Many dive computers have a battery warning indicator. If you see a low-battery signal, do not ignore it. A dive computer failure underwater can leave you without critical information, such as depth or remaining no-decompression time.
4. Visible damage or corrosion
Check for visible signs of damage or corrosion on all equipment. Cracked hoses, frayed straps, or corroded metal parts indicate that your equipment needs immediate professional attention.
Tips for maintaining your dive equipment between servicing
1. Rinse thoroughly after every dive
After each dive, rinse your gear thoroughly in fresh water to remove salt, sand, and chlorine. Pay particular attention to moving parts, such as regulator second stages, inflator mechanisms, and buckles.
2. Store gear properly
Store your dive gear in a cool, dry place away from direct sunlight. Prolonged exposure to heat and UV light can degrade the materials. Keep your regulator in a regulator bag to protect it from dust and physical damage.
3. Inspect gear regularly
Conduct a visual inspection of your gear before every dive. Check for loose fittings, worn straps, and signs of damage. Catching small issues early can prevent larger problems from developing.
The role of a certified technician
1. Expertise and knowledge
Certified technicians are trained to inspect, maintain, and repair dive gear according to manufacturer specifications. They use specialised tools to calibrate regulators, replace parts, and test performance under simulated diving conditions.
2. Manufacturer warranty compliance
Most dive gear warranties require regular servicing by certified technicians to remain valid. Using a certified service provider ensures that your warranty remains in effect, giving you added peace of mind.
Common mistakes to avoid
1. Skipping annual servicing
Even if your gear seems to be functioning well, skipping annual servicing can result in unnoticed wear and tear leading to unexpected and potentially catastrophic failure. Regular servicing is essential for catching potential issues early.
2. DIY servicing without proper knowledge
Many divers attempt to service their own gear without adequate training. While basic maintenance such as rinsing and visual inspection is fine, attempting repairs without proper knowledge can lead to equipment failure and increase safety risks.
3. Ignoring manufacturer recommendations
Always follow the manufacturer’s guidelines for servicing intervals and procedures. Ignoring these recommendations can lead to equipment malfunctions and void warranties.
Conclusion
Servicing your dive equipment is a crucial part of being a responsible diver. Your gear is your lifeline underwater, and ensuring it is in top condition is key to your safety and enjoyment. By following recommended servicing intervals, working with certified technicians, and conducting routine maintenance, you can dive confidently, knowing your equipment will perform as it should. Remember, the cost and time involved in servicing are small compared to the value of a safe and enjoyable dive.
