Caring for your scuba cylinders (also called tanks) is essential to ensure their longevity, safety, and optimal performance. Proper maintenance and regular checks are crucial to ensure they remain safe to use during dives. Here are some key steps for caring for your scuba cylinders:

1. Regular Visual Inspections

Before every dive, inspect your scuba cylinder visually for signs of damage, wear, or corrosion. Look for:

• • Dents, gouges, or cracks: These can compromise the integrity of the cylinder.
  • Corrosion or rust: Especially on the exterior, as it can weaken the tank.
  • Valve condition: Ensure the valve operates smoothly and there are no signs of leaks.
  • O-ring condition: The O-ring on the cylinder valve should be intact, clean, and properly lubricated.

2. Cleaning the Cylinder

Exterior Cleaning: After each dive, rinse your scuba cylinder with fresh water to remove any saltwater, sand, or dirt. This prevents corrosion and buildup on the surface.

• • Dry the tank thoroughly after rinsing to avoid rusting.
  • For stubborn dirt, use a non-abrasive cleaner and a soft cloth.

Interior Cleaning: Over time, the inside of the cylinder can accumulate moisture or contaminants, which may affect air quality or cause corrosion.

• • Have your tank cleaned professionally. Scuba Warehouse offers such service.

3. Inspect and Maintain the Valve

Valve Check: The valve is one of the most critical parts of the scuba tank. Before each dive, check the valve to ensure it’s fully operational.

• • Check for leaks by turning the valve slightly on and off, and listen for any air escaping.
  • Clean the valve O-ring and lightly lubricate it (with appropriate silicone lubricant) to keep the seal tight and prevent leaks.
  • Periodically check that the tank valve threads are free from damage or wear.

4. Hydrostatic Testing

Hydrostatic testing is a critical test to check the integrity of the tank. This test involves filling the cylinder with water and pressurizing it to detect any deformation or weaknesses.

• • Frequency: Hydrostatic testing is required by law (in many countries) every 5 years. You should ensure that your tank is hydrostatically tested by a certified professional according to local regulations.
  • If your tank fails a hydrostatic test, it should be retired and replaced, as it’s no longer safe to use.

5. Regular Visual Inspections (VIP)

In addition to the hydrostatic test, scuba tanks require an annual Visual Inspection (VIP). This is typically done by a professional who will inspect the cylinder for any issues that could affect safety.

• • This inspection checks the cylinder’s overall condition, including the valve, threads, O-ring, and exterior.
  • A VIP should be done every 12 months, regardless of whether the tank has been used or not.

6. Proper Storage

Store tanks upright: Always store your scuba cylinder standing up in a secure, vertical position to avoid any pressure on the valve.

Avoid temperature extremes: Store tanks in a cool, dry place away from direct sunlight, extreme heat, or freezing conditions. Temperature changes can cause the tank’s internal pressure to fluctuate, which may lead to damage.

Keep away from chemicals: Do not store your tank near chemicals or other substances that could corrode or damage it.

Use a tank rack: When storing multiple tanks, use a tank rack to keep them secure and prevent rolling or accidental falls that might damage the tank or valve.

7. Air Quality Control

Fill with clean air: Always ensure that the air in your cylinder comes from a reliable and well-maintained air compressor or filling station. Contaminated air can damage the tank or affect your health.

Avoid overfilling: Never fill your tank beyond the recommended working pressure (usually indicated on the tank’s label). Overfilling can lead to dangerous situations.

8. Avoiding Overuse of the Tank

Do not use the cylinder until it is completely empty or overly close to empty, as this can cause damage to the valve and internal components. It’s a good practice to leave some air in the tank.

Don’t drop or hit the tank: Always handle your tank with care. Dropping or bumping it can cause structural damage, which may not always be visible but could lead to cracks or leaks.

9. Replacement of O-Rings

The O-ring is a critical part of the tank valve. Over time, it can wear out, crack, or become damaged.

• • Regularly check the O-ring and replace it if it shows signs of wear, cracking, or damage. It’s always a good idea to carry a few extra O-rings with you while diving.

 

If you’re unsure when your tank is due for a hydrostatic test or VIP, you can always contact Scuba Warehouse to schedule these checks.
