Robert, I had the same problem with mine. On the advice from Dave Merriman I drilled out the vent hole to 3/16" and that cured it. I can have it under in 30 sec. if I hold down on the lever. However If you dont get the hole dead center it will not seal. In that case just pull off the blue rubber stopper valve and re-silicone it so that the bump fits perfectly up into the enlarged hole.
