Phil,
Last night when Bob came over I put a piece of hose on the vent tube at each end on his tank. No way could I blow through it in either direction. And as you know, I am quite the blowhard. It is defenitely plugged up. I tried to stick a pipe cleaner in it to see if I coutube seems to take an immediete 90º bend that is too sharp for the pipe cleaner. I then shoved it in from the underside and got about 6" before it just stopped and would not go any further.
I don't see anyway to clear it out or even get to the tube without destroying the tank since it's all inside the tank. Looks like a new warranty tank is called for.
