When the season ends and it's time to put away your towable tube, many people likely think, "I'll just deflate it and toss it in the closet." However, incorrect deflation and storage methods can accelerate material degradation and damage valves, potentially leaving your equipment unusable for the next season. To extend the life of your towable tube, proper deflation procedures and appropriate storage are essential.
Why Proper Deflation and Storage are Important
Towable tubes are mainly made of PVC (polyvinyl chloride) or reinforced nylon, materials that are sensitive to ultraviolet (UV) rays, heat, and moisture. Storing them while inflated puts unnecessary stress on valves and seams due to internal pressure fluctuations caused by temperature changes. Conversely, folding them without fully deflating them can cause uneven creasing, making those specific areas prone to cracking or whitening. Careful care significantly affects the product's lifespan.
Correct End-of-Season Deflation Procedure
Check the Valve Type
Towable tube valves vary by manufacturer and product, with several standards such as Boston valves, pin valves (needle valves), and screw-type valves. Damaging the inside of the valve through improper operation can lead to air leaks, so be sure to check the valve shape in the instruction manual before beginning.
Deflate in Stages
- Spread it out on a flat surface: Lay the tube out in a clean area free of gravel or sharp protrusions.
- Remove the valve cap: Caps are easily lost, so put it in your pocket immediately after removing it.
- Open the valve: For a Boston valve, turn the inner cap counterclockwise to open. Do not push it in forcefully; let the air escape naturally.
- Push out remaining air by hand: Gently press with your palms starting from near the valve toward the edges to push out the air. The key is not to fold it with excessive force.
- Close the valve and attach the cap: Once all air is out, close the valve securely and reattach the cap to avoid losing it.
Cleaning and Drying Before Storage
It is important to rinse the entire tube with fresh water before or after deflating. Storing the tube with seawater, salt, sand, or sunscreen residue significantly accelerates material degradation. The area around the valve is particularly prone to sand buildup, so rinse it carefully with running water.
After cleaning, let it dry completely in a well-ventilated, shaded area. Storing the tube in a bag while even a trace of moisture remains can lead to mold and odors. Drying can take anywhere from several hours to half a day depending on the conditions. Do not rush to store it; confirm by touch that it is completely dry.
Tips for Folding and Storage
Once dry, fold it loosely or roll it up in a way that minimizes creases. Folding it in the same place every time creates permanent creases that damage the material, so it is recommended to slightly change how you fold it each time.
- Tuck ropes and handles inside so they do not stick out.
- If you have the included storage bag, use it to protect the tube and avoid applying unnecessary pressure.
- Do not place heavy objects on top.
Choosing a Storage Location
The biggest causes of degradation for towable tubes are UV rays and heat. Car trunks or outdoor areas exposed to direct sunlight can become very hot during the summer, which can cause the PVC material to harden, discolor, and crack. Ideal storage conditions are as follows:
- Indoors, out of direct sunlight (e.g., in a shed or the shaded part of a garage).
- Low humidity with good ventilation.
- Away from sharp tools or heavy equipment.
- Away from areas where mice or pests can enter.
For long-term storage (during the off-season), it is even safer to place the tube in a UV-protective storage bag or cover it with a black cloth to block light.
Pre-Season Inspection Points
Check the condition of your equipment before using it after storage. If the pressure drops significantly after inflating and leaving it for a few hours, air leaks from the valves or seams are suspected. In that case, it is safest to apply soapy water around the valve to find where bubbles form, and then consult with a repair kit or the manufacturer. Also, check for wear on handle ropes and rust on metal fittings, and replace them before use if any abnormalities are found.Frequently Asked Questions (FAQ)
Q. Can I store it with a little air left inside?
We generally recommend storing it completely deflated. Leaving air inside causes the internal pressure to fluctuate with temperature changes, increasing the load on valves and seams. However, some products may have instructions to leave a small amount of air; please check your instruction manual.
Q. What should I do if mold grows?
For mild mold, wipe it off with water diluted with mild detergent and dry it thoroughly. Avoid bleach or organic solvent cleaners, as they may damage the material. If the mold has taken deep root, it is more practical to consider replacing the item, taking into account hygiene and the condition of the material.
Q. What if I lose the valve cap?
Without a valve cap, foreign objects can easily enter the valve, leading to air leaks or operation failure. You may be able to obtain a cap that matches the valve standard at a hardware store or specialty shop. If the standard is unknown, inquire with the manufacturer or check for replacement parts specific to your product.
Q. Is there a protective spray I can use on PVC?
There are commercially available UV-protective care sprays for PVC or protectants for inflatable boats. Confirm material compatibility before use, and be careful not to spray directly onto the valve.
To Use Your Valuable Equipment for a Long Time
Although towable tubes are consumable items, practicing the correct deflation and storage methods can greatly increase the number of seasons you can use them. Making the basics of cleaning, drying, proper folding, and choosing the right storage location a habit is the most cost-effective form of maintenance.
