My holding tank is building up pressure during use and I figured it wasn't venting properly. I found that the venting hose seemed to clogged with no ventelation...I followed it and it is attached to the bottom of a stanchion in a spot behind the head medicine cabinet that I can't get to without removing the medicine cabinet. BUT, I'm looking at the stanchion above decks and there is no sign of a vent hole!? The holes the lifelines go through are sealed with tubes. Any ideas? Could the base be clogged? Should I drill a hole in the stanchion?
