Air Valve Replacement Quick Instruction

  • To replace the air valve, you can first inflate the chamber to 3 PSI. First to loose the valve when chamber (Boat or SUP) inflated, use the valve winch to turn it by counter-clockwise, pressure down the tool by your another hand in case it slip out. You may turn it for about 1 round until spinning.
  • Lay down the chamber (Boat or SUP) on the flat floor, Manually deflate the chamber completely before you can unscrew the air valve out.  You don’t need to change the valve seat that inside the chamber. At the mean time don’t let it fall into the chamber, otherwise it is hard to get it back to the original position.
  • Optional to add some silicone to air valve thread. Or if you used to have air leaking at the valve edge before and tight up the valve no help, then you should add some on to get it a better seal and fixed.  If you add the silicone to your valve, we suggest to keep 24 hours before you next use. And chamber pressure best to keep 1 PSI after valve replaced.
  • Same way to screw in the air valve to the valve seat. First by hand until no more moving. Then you can use the valve winch to keep turning. Also holding the bottom tight via the chamber. Maybe you can turn 1 or 2 round until no more.
  • Inflate the chamber to 3 PSI. and you can keep using the winch to final turn it tight. You may be able turn half round or more until final tight.
  • When you turn the winch very hard, always remember use another hand to pressure it down toward the valve, the tool slip out from the valve may cause its teeth damage.
  • Use the 5% liquid soapy water to check the air leaking. Easy to use a water bottle and drill a pin hole (1/64”) on its cap as a DIY tool.
