How to Check and Repair a Leaking Inflatable Boat

(+ Video Guide Included!)

A leaking inflatable boat can turn a fun day on the water into a frustrating one—but don’t worry! Most leaks can be fixed easily with the right tools and a bit of patience. In this guide, we’ll show you how to inspect and repair your inflatable boat step-by-step, from tiny punctures to valve issues.

1. Visual Inspection

Start with a full visual inspection:

• Inflate the chambers fully.

• Use your ears and listen for hissing sounds.

• Spray or brush soapy water around the seams, valves, and surfaces.

• Look for bubbles—this is your leak location!

• Mark the leaking spot with a pen.

2. Checking for Valve Leaks

Valves are a common source of slow leaks. There are two typical types:

a. Valve Edge Leaking

• Loosen the valve's upper ring by turning it half a turn counterclockwise.

• Use a valve tool to tighten it securely.

• If leaking continues, remove the top part, clean the seal area with alcohol, and reassemble carefully.

⚠️ Tip: Don’t let the bottom piece fall into the chamber!

b. Valve Center Leaking

• Inflate and deflate the valve several times.

• Still leaking? You may need a replacement valve. Contact your boat’s manufacturer.

3. Repairing Small Damage (Less Than 2 Inches)

If you’ve found a small puncture, here’s how to fix it yourself using a PVC repair kit:

Step-by-Step:

1. Mark the leak.

2. Cut a rounded PVC patch at least 2 inches larger than the damage.

3. Outline the patch area with painter’s tape.

4. Sand the boat surface and the patch lightly.

5. Clean both areas with acetone.

6. Apply a thin coat of glue to both sides. Wait 30 minutes.

7. Apply a second coat. Wait 10 minutes.

8. Deflate the boat and lay it flat.

9. Press the patch firmly into place using a roller or screwdriver handle.

10. Let it cure for at least 24 hours.

✅ After curing, re-inflate the boat and use soapy water again to make sure the leak is sealed.

4. Repairing Large Damage or Tube Seams

If the damage is larger than 2 inches, or you notice leaks at the tube seams, it’s time to call in the pros.
Large repairs require strong adhesives, precision, and sometimes heat-bonding techniques only professionals can safely apply.
