This is part of normal maintenance and it is why we include the wrench in your order! If you aren't sure what to look for, we have attached photos below. Simply use the valve wrench to tighten the valve. We recommend checking this regularly.
Please note: the valve wrench is used to tighten and remove the valve. Please DO NOT use the wrench to deflate the board. Deflating the board should be done with the pin on the valve.
