Maintenance of Double Valve Snorkels
Proper maintenance ensures optimal performance, hygiene, and longevity of your double valve snorkel. Following these guidelines will help protect your investment and ensure safe, enjoyable snorkeling experiences.
Maintenance Tip: After each use in saltwater, soak your snorkel in fresh water with a tablespoon of white vinegar for 30 minutes to prevent salt crystal formation and mineral buildup on valves.
Essential Maintenance Routine
- Post-Use Rinse: Immediately after each use, thoroughly rinse the snorkel with fresh water to remove salt, sand, and debris that can damage valves and components.
- Deep Cleaning: Periodically disassemble the snorkel (if possible) and clean each component separately with mild soap solution, paying special attention to valve mechanisms.
- Inspection: Regularly check for wear, cracks, or damage, particularly on valve flaps and mouthpiece. Replace worn or damaged components promptly.
- Proper Storage: Store the snorkel in a dry, cool place away from direct sunlight to prevent UV damage and material degradation.
- Chemical Exposure: Avoid exposing your snorkel to harsh chemicals like chlorine for extended periods, as they can degrade materials and compromise valve function.
- Transportation Protection: Use a protective case or dedicated snorkel bag to prevent scratches and damage when traveling.
- Valve Maintenance: Apply silicone grease or appropriate lubricant to valve flaps and moving components periodically to maintain smooth operation and proper sealing.
- System Testing: Before each use, check valve function by gently blowing through the snorkel to ensure proper operation and water resistance.
Warning: Never use petroleum-based lubricants on silicone components as they can cause material degradation and potential failure. Always use silicone-safe products specifically designed for water sports equipment.

DIY and Replacement Guide for Double Valve Snorkels
Whether you're replacing a worn-out snorkel or performing maintenance on your current one, this step-by-step guide will help you complete the process efficiently and safely.
Important Safety Note: Always ensure any DIY modifications or replacements maintain the water-tight integrity of the snorkel. Improper modifications could lead to water intrusion and potential safety hazards.
Step-by-Step Replacement Process
- Gather necessary tools and equipment: Prepare a small screwdriver (typically Phillips), pliers, silicone lubricant, and any replacement parts specific to your snorkel model.
- Clean the work area: Ensure you have a clean, well-lit workspace to prevent losing small components or introducing debris into the snorkel mechanism.
- Disconnect and disassemble: Carefully remove any fasteners or connectors holding the snorkel components together, keeping track of their original positions.
- Inspect all components: Thoroughly examine each part for wear, cracks, or damage before proceeding with replacement.
- Clean the snorkel housing: Remove any debris, salt buildup, or old lubricant from the snorkel body before installing new components.
- Install new components: Carefully insert replacement parts, ensuring proper alignment and orientation according to manufacturer specifications.
- Reassemble the snorkel: Secure all components following the reverse order of disassembly, being careful not to overtighten plastic fasteners.
- Test the valve system: Verify proper operation by gently blowing through the snorkel and checking for valve movement and sealing.
- Conduct a water test: Before using in open water, test the snorkel in a controlled environment like a sink or bathtub to ensure proper function.
DIY Tip: When replacing valve components, take clear photos of the original assembly before disassembly. This visual reference can be invaluable when reassembling complex valve mechanisms.
Common DIY Fixes for Double Valve Snorkels
| Issue | Possible Cause | DIY Solution | When to Replace Instead |
|---|---|---|---|
| Water leaking through valve | Debris in valve, worn valve flap | Clean valve thoroughly, apply silicone lubricant | When valve flap is torn or deformed |
| Mouthpiece discomfort | Worn material, incorrect size | Boil water, reshape mouthpiece (if silicone) | When material is cracked or degraded |
| Cracked tube | Impact damage, UV degradation | Small cracks: silicone marine sealant | When crack compromises structural integrity |
| Loose connections | Worn fasteners, stripped threads | Tighten properly, use thread tape if needed | When threads are completely stripped |

Frequently Asked Questions about Double Valve Snorkels
While double valve snorkels can be more complex than basic models, many designs are actually ideal for beginners. Purge valve snorkels, a common type of double valve design, are specifically recommended for novices as they simplify water clearing. The added valve technology helps prevent water intrusion and makes the snorkeling experience more enjoyable for those still developing their technique.
Beginners should look for models with easy-to-use purge valves and comfortable mouthpieces, prioritizing user-friendly features over advanced performance characteristics.
Yes, many double valve snorkels can be repaired when damaged, depending on the nature and extent of the damage. Minor issues such as small tears in silicone components can often be addressed with silicone sealant designed for water sports equipment. Valve mechanisms can frequently be cleaned or replaced without needing to purchase an entirely new snorkel.
However, if structural components are compromised or if there are extensive tears or cracks, replacement is typically the safer option. Always prioritize safety over cost savings when deciding whether to repair or replace.
Double valve snorkels can be used for freediving, particularly high-performance models designed with streamlined profiles and minimal drag. These snorkels allow freedivers to breathe comfortably at the surface between dives without having to remove their masks.
However, it's important to note that during the actual freediving descent, the snorkel is not used for breathing underwater. Instead, freedivers typically hold their breath during dives. The double valve feature is primarily beneficial during surface swimming and recovery between dives, preventing water from entering the tube during splashing or brief submersions.
While not always strictly necessary, using a snorkel keeper with a double valve snorkel offers several important benefits. The keeper securely attaches the snorkel to your mask strap, preventing loss if it gets knocked away during water activities. This is particularly valuable for more expensive double valve models.
Additionally, a properly positioned snorkel keeper helps maintain the optimal angle of the snorkel relative to your mouth, improving comfort during extended use. For activities in rougher water conditions, a snorkel keeper becomes even more important as it prevents the snorkel from being dislodged by waves or currents.
With proper care and maintenance, a quality double valve snorkel can last 3-5 years of regular use. Premium models with high-grade materials may last even longer. The lifespan depends significantly on several factors:
- Frequency of use and exposure to harsh conditions
- Proper cleaning and storage practices
- Quality of materials and construction
- Exposure to UV radiation and chemicals like chlorine
Regular inspection of valve mechanisms and replacement of worn components can significantly extend the functional lifespan of your snorkel.
