My covers are needing to be replaced for my 22.5 and OTG 26.75 and I'm looking for a solution to work in conjunction with the new covers to really keep the moisture out of the pit and grill. I recently spotted a small water puddle inside the wsm. I keep them covered with dampers closed. There are no leaks around the body rings so I'm wondering how water worked it's way inside to begin with. I recently installed CB grommets for my temp control unit along with the mount for the fan. The fan mount appears to be flush so it could be the grommets however those holes are tiny and the Weber cover drapes over them so not sure how this keeps happening. I'm tempted to go to the hw store and get some heavy duty plastic to go over the weber covers but that would draw the ire of my better half.....any advice will be greatly appreciated.
