How to Tell if Your Paddle Board Valve Is Loose

Your paddle board valve is designed to keep air sealed inside the chamber at high PSI. If it becomes loose during shipping, storage, or regular use, you may notice a few clear signs:


  1. Hissing Noise Around the Valve
    When your board is inflated, listen closely around the valve area. If you hear air escaping, that’s a giveaway.

  2. Bubble Test
    Pour a small amount of water over the valve. If bubbles appear, it means air is escaping through a loose seal.

  3. Board Won’t Stay Inflated
    A properly working valve will hold air for days or weeks. If your board deflates quickly after pumping it up, a loose valve is the likely culprit.


⚠️ Don’t ignore these signs. A leaking valve won’t just cut your session short — it can also put unnecessary stress on your board’s seams.


Tools You’ll Need

Fortunately, every Glide inflatable paddle board comes with a repair kit that includes the black plastic valve wrench. This is the key tool for fixing a loose valve. You’ll also need:


  • Your SUP pump (manual or electric)

  • A towel or sponge for the bubble test

  • A bit of patienceHow to unbox your inflatable sup



Step-by-Step: How to Fix a Loose SUP Valve

Follow these steps to get your board sealed tight and ready for the water again:

1. Inflate the Board for Diagnosis

  • Use your manual or electric pump to inflate the board.

  • Note: hand pumps typically don’t register PSI until 7–10 PSI, so don’t panic if the gauge isn’t moving right away.

  • Once inflated, listen for hissing near the valve or test with water.

2. Confirm the Leak

  • Pour a small amount of water over the valve.

  • Look for bubbles rising up — if you see them, the valve is loose and needs tightening.

3. Deflate the Board Completely

  • Before making adjustments, fully deflate your SUP.

  • This removes air pressure from the chamber, making it safe to tighten the valve.

4. Tighten with the Valve Wrench

  • Find the black wrench in your repair kit.

  • Press firmly down around the valve with one hand.

  • Insert the wrench into the valve head.

  • While holding pressure downward, twist the wrench clockwise until snug.

  • Think of it like screwing a bolt into a wall: it should be secure but not forced to the point of stripping.

5. Double Check the Seal

  • Try twisting the outer valve with your fingers.

  • If it doesn’t move under light pressure, the valve is tight enough.

6. Reinflate and Retest

  • Pump the board back up to your normal PSI (12–15 PSI for most Glide inflatables).

  • Listen for any hissing.

  • Do the bubble test again to confirm the leak is gone.

✅ If the board holds air without noise or bubbles, you’re ready to paddle!


Pro Tips for Paddle Board Valve Care

  • Check During Unboxing: Inspect your valve as soon as you open your new board. Shipping jostles can sometimes loosen it.

  • Regular Maintenance: Do a quick bubble test at the start of the season. Preventing leaks is easier than mid-session fixes.

  • Don’t Overtighten: Valves are tough, but stripping the threads can cause bigger issues. Snug, not forced, is the goal.

  • Keep It Clean: Rinse your board after use in saltwater or sandy conditions to prevent debris buildup around the valve.


When to Call for Support

Most valve issues are solved with a quick tightening. But if your valve continues to leak even after adjustments, the problem could be a:

  • Damaged O-ring or gasket

  • Cracked valve housing

  • Improper factory seal

If that’s the case, don’t worry — Glide backs every inflatable with a 5-year warranty. Reach out to our team at info@glidesup.com
