1).I hear air or see bubbles from around the paddle board valve. What should I do?
Over time and frequent use, it is possible that the inflation valve can become slightly loosened. Not to worry–a simple tightening is all that is necessary. Using the valve wrench, gently tighten the valve by turning a quarter or half turn clockwise. You may need to turn the valve more or less depending on how loose it is, but it should not take excessive force to do so.
2).If the above method does not work, how should I do？
First of all, you can use the wrench in the orange repair kit to remove the air valve, then adjust the position of the air valve, and reinstall and lock it.
