Why Won't My Paddleboard Hold Air? Valve Position Explained

The short answer

If air is rushing straight back out as you pump, your valve pin is in the down (deflate) position. Press the pin and let it spring back up to the raised (closed) position, then inflate as normal. That single click is the fix for the vast majority of "my board won't hold air" cases.

How your Wave valve works

Your Wave SUP has a spring-loaded valve with a small pin in the centre that clicks between two positions. Which position it's in decides whether your board holds air or lets it out.

The mistake that catches almost everyone: after you deflate (pin down), you go to pump the board back up without popping the pin back to the raised position. With the pin down, every stroke you push in comes straight back out, and it feels like the board simply won't inflate. Nothing is broken — the valve just needs setting back to inflate mode.

The two-second fix

1. Take off the valve cap and look at the pin in the centre of the valve.
2. Press the pin down and release it so it springs up. You want it in the raised (closed) position — the same position you inflate and paddle in.
3. Connect your pump hose and click the lock (a quarter-turn so it can't blow off).
4. Inflate to 18 PSI as normal, up to 20 PSI for High Performance Mode.
5. Disconnect and cap off. A brief hiss as the hose comes away is normal — that's just the air in the hose, not your board.

Want to be sure it's holding? Note the reading on your pump gauge, leave the board a few minutes, then check again. If the pressure is steady, you're good — the earlier problem was simply the pin position.

Still losing air? Work through these

If the pin is raised and the board still won't hold pressure, run down this list before assuming anything's faulty:

• Air leaking from around the valve, not through it. The whole valve body may have worked slightly loose in its housing. Push the pin fully down, then use the valve tool from your repair kit to tighten the valve clockwise until secure. Take care not to over-tighten.
• Debris in the valve. Sand or grit on the sealing surface stops the valve closing cleanly. Open the valve, rinse the area with fresh water, let it dry, and try again.
• The cap is loose — but that's not your leak. The valve cap keeps dirt out; it isn't what holds the pressure. Your board stays firm because the valve seals, not the cap. So if you're losing air with the cap off, look to the pin and valve body, not the cap.
• A leak somewhere on the board. If the valve checks out, the air may be escaping from a seam or a small puncture. Brush soapy water over the board and watch for bubbles to pinpoint it — then see our repair guide.

When the valve itself needs attention

In the rare case a valve is damaged, it can be replaced without any specialist kit. Fully deflate the board, use the valve tool anticlockwise to release and remove the valve, then fit a replacement. If you're at all unsure, don't force it — our team can talk you through it or arrange a valve under warranty.

Speaking of which: a valve or seal that's failed through a manufacturing fault is covered by your 2-year Wave warranty. Damage from over-inflation or grit left in the valve counts as wear or misuse, so a quick rinse and a gauge check go a long way to keeping both your board and your cover in good shape.

Quick reference

Still stuck?

If you've set the pin to raised, tightened the valve, and cleared any debris and the board still won't hold air, get in touch before you paddle. Have your order number and a photo of the inflated board handy — it helps us sort things quickly.
