In this video, you can see where I plugged off the outlet tube to get pressure to build up inside the O.C.V. Well when the pressure builds, you can see where the relief starts venting out the front relief and the cap never blows completely off ! The cap lifts ,but only high enough to open the relief vent. That was with 8 grams of oxalic acid and the outlet vent completely plugged. !!! :) Thank you Lord for that guidance.
