I've been rebuilding the same coils for awhile now, and suddenly my husband who actually is the one who vapes is saying that they flooding. He thinks it's the o-ring for the bottom of the tank. I'm pretty positive it's the coil gasket that goes around the chimney. I can find his o-rings, but for the life of me I cannot find the coil gaskets. I bought a combo pack off of ebay but they ended up being for the protank 2 which has shorter gaskets on it so they don't do what I want them to do. So I figured I'd ask on here since I've been lurking around the site for the last few months and not coming up with answers.
