Pelican performs a visual inspection of all coolers at the end of the manufacturing process to ensure the coolers are of the highest quality. Unfortunately, a visual inspection is not always able to catch something like a drain plug that isn’t tight enough. The good news is that tightening your drain plug is pretty simple.You'll need a T20 Torx screwdriver, a flathead screwdriver, and a hammer.Unscrew the free-spinning drain cap. Remove the anti-rotation screw using the T20 Torx screwdriver. Set the drain cap and anti-rotation screw to the side.Tighten drain plug assembly:Insert a flathead screwdriver into one of the notches in the drain collar. Tap the screwdriver with a hammer to turn the drain collar in a clockwise direction.Test drain plug assembly:Screw the free-spinning drain cap onto the drain collar. Fill the cooler with enough water to cover the entire drain plug assembly. Tilt the cooler up and leave for fifteen minutes. If a leak occurs, tighten the drain plug assembly and retest.Install a free-spinning drain capRemove the free-spinning drain cap from the drain collar. Align the washer at the end of the tether with the anti-rotation screw hole in the drain collar; be sure to face the flat side of the washer toward the drain collar. Install the anti-rotation screw; it may not be possible to align the anti-rotation screw directly where it was installed in the previous drain plug assembly. Do not overtighten—over-tightening the screw will reduce retention.Be aware: due to the design of the free-spinning cap, the cap will not sit flush with the drain collar. As long as the drain cap is fully tightened and the drain cap washer is in place correctly, the drain cap will not leak.If this does not help with your drain plug's leak or you have other concerns about the leak, please reach out to us at sayhello@elitecooler.com
