Step 3

Spray all sealing surfaces of the enclosure with all-purpose leak detector fluid or soapy
water. Look for bubbles forming to determine if there are any leaks. If there are any failures
in the seal, bubbles will appear and increase in size from any air escaping from the
pressurized enclosure.

Step 4

Release air pressure by pressing the bump on top of the air valve cap down on the
enclosure's valve stem.
In the case of air leakage, reseal the box according to Step 19. If there is no air leakage,
reinstall the air valve cap back onto the air valve before burial.
