Question for TDI staff member or instructor or anyone else out there who knows the TDI standard for valve drills. I've got an aluminum 80 with an H-Valve that I fool around with in the pool to practive manipulating valves and I was wondering what are the steps for executing a valve drill on an H-Valve? I know how to do a valve drill on manifold doubles but will probably be doing some light deco using steel 119 with H valve so I'd like to get up to speed on the valve drill if there is one... Thanks in advance.
