How To Fix Your iSUP Valve

There's nothing that will fill you with dread faster than seeing air bubbles and hearing the hiss of air escaping from your inflatable paddle board while you're out paddling around. Except seeing a great white tailing you; that would be worse.

The good news is that inflatable paddleboard repair is so much easier than fixing dings on a hard paddle board. We'll review the repair process here and explain different techniques for locating leaks and applying patches to get rid of those pesky leaks once and for all. Don't fret- small holes are an easy fix.

Key Highlights

  1. Identifying the Leak: Start by inflating your SUP and applying a soapy water solution to spot persistent air bubbles indicating leaks.
  2. Preparing the Surface: Thoroughly dry and clean the leak area with rubbing alcohol before any patch application.
  3. Patch Application: Apply PVC glue to both the patch and the SUP, press firmly to adhere without gaps, and allow to cure overnight for best results.
  4. Using Self-stick Patches: For quick, minor repairs, self-stick patches offer a convenient, no-mess solution.
  5. Valve Maintenance: Tighten the valve with the included wrench to prevent air from escaping. Regular checks ensure the valve remains tight and functional.
  6. Post-Repair Testing: After repairs, re-inflate and recheck the area with soapy water to confirm the leak is sealed.

Let's Learn How to Fix your iSUP Valve

At Glide, we understand that your inflatable SUP is more than just a piece of equipment—it's your gateway to adventure on the water. That's why we've included a repair kit with every Glide inflatable SUP purchase. But if you've misplaced yours or are in need of a refresher on how to use it, don't worry! Repairing your SUP is straightforward and affordable, with PVC patches and glue usually costing between $10-$20.

Finding and Preparing for the Repair

The first step in any repair is locating the leak. This can sometimes be a challenge, but an effective method is to inflate your SUP to at least 1 PSI and then gently pour water mixed with a little dishwashing detergent over it. Look for persistent bubbles, which indicate a leak. Once found, dry the area thoroughly and clean it with rubbing alcohol. If the damage is near a critical feature like a D-ring or pad, consider how the patch's shape might need to adapt while aiming for a round patch when possible.

Applying the Patch

With your SUP deflated and the area prepped, apply a thin layer of PVC glue to both the patch and the board. Press them together firmly, ensuring no edges are left unattached. Wiping away excess glue will keep the repair area clean and reduce dirt accumulation. It's crucial to allow the patch to cure properly, typically overnight, to ensure a strong bond.

The Convenience of Self-stick Patches

In addition to traditional patches, we recommend keeping self-stick patches on hand. These patches, which don't require glue, offer a quick and mess-free solution for minor repairs. Simply peel and stick for an instant seal.

Checking the Repair and Addressing Valve Leaks

After allowing adequate time for the glue to cure, re-inflate your SUP and reapply the soapy water mixture to check for leaks. While patch failures are rare, they can happen, and a secondary patch might be necessary. Valve leaks, often due to loosening over time, are another common issue. Thankfully, they're easily fixed with the valve wrench included in your repair kit. A snug tightening of the valve should resolve most air escape problems.

FAQs

Why is my inflatable SUP losing air?

Most air loss comes from a slow leak, a loosened valve, or a small puncture. Luckily, all three are easy DIY fixes using your SUP repair kit and soapy water to locate the issue.


How do I know if the valve is the problem?

If bubbles appear around the valve when you apply soapy water, the valve likely needs tightening. Use the valve wrench from your repair kit and give it a firm—but not aggressive—twist.


How tight should the valve be?

Hand-tight isn’t enough. Use your valve wrench and snug it down until it no longer wiggles. Over-tightening isn’t common, but avoid forcing it beyond resistance.


What kind of glue should I use for patching my inflatable SUP?

Use PVC-specific adhesive only. General adhesives won’t bond properly and may fail. Glide repair kits include the correct glue, but any high-quality PVC glue works.

How long should my patch cure before reinflating?

Ideally, let the patch cure overnight (8–12 hours). Faster cures are possible, but allowing full curing ensures the strongest bond and longest-lasting repair.


Can I use self-adhesive patches instead of glue?

Yes—self-stick patches are great for quick, temporary fixes. For long-term repairs, glued PVC patches are stronger and more durable.

What if my patch still leaks after curing?

It’s rare, but you may need to apply a second patch or replace the first. Re-clean, reapply glue, and use a slightly larger patch for better coverage.


Why are Glide inflatable SUPs easier to repair than cheaper Amazon boards?

Glide uses higher-grade PVC and heat-fused construction, which bonds better with PVC adhesives and self-stick patches. Many cheap Amazon boards use thin, low-quality PVC that delaminates or doesn’t hold glue well.

Do I need professional repair for a leaking valve?

Almost never. Valve tightening fixes 95% of valve leaks. Only damaged valve housings require professional service—and Glide can help if that happens.

What should I do if I can’t find the leak?

Inflate your SUP slightly above normal PSI, use soapy water generously, and check seams, rails, and around the fin box. Stubborn leaks are usually valve-based.
