Whether you’re paddling along the Amalfi Coast, cruising on a calm lake in Austria, or exploring a hidden cove in Croatia, nothing can ruin a perfectly good paddleboarding experience like a leaky paddle board. If you find that your inflatable paddle board isn’t holding air pressure like it used to, don’t panic—most leaks are easy to fix.
This guide will help European paddlers identify the most common leak causes and how to fix them, so your Funwater paddle board stays in top shape all season long.
Common causes of leaks on inflatable paddle boards.
Leaky valves
The most common cause. If your valve is improperly installed or the O-ring is damaged, air can slowly escape.
Tighten the valve using a valve wrench (usually provided with your Funwater SUP board). If the leak persists, replace the O-ring.
Damaged seams
Seams can peel or weaken, especially if the paddle board is not stored properly or exposed to excessive heat.
Solution:
Clean the area and apply the PVC patch using waterproof adhesive. Allow to dry completely before inflating.
Punctures from sharp objects
Rocks, shells, and even rough transport can cause small holes in the fabric.
Solution:
Inflate the SUP and spray it with soapy water to find bubbles. Mark the hole, dry the area, and apply the repair patch.

Wear and tear of materials
Older SUP boards can start to deteriorate over time, especially cheaper models that aren’t made of durable PVC.
Solution:
If the material itself is cracking or flaking, it may be time to upgrade to a sturdier model – Funwater paddle boards are made from military-grade PVC, designed to handle the harsh conditions found throughout Europe.

How can you prevent future leaks?
Always dry and deflate after every use especially in saltwater.
Store in a cool, dark place when not in use, away from direct sunlight or freezing temperatures.
Avoid dragging your SUP board over rocks or rough surfaces.
Check the pressure regularly - most inflatable paddle boards work best between 12-15 PSI.
