my whole house water filter was tightened last with the o ring in between the casing and the base, just under the threads of the casing (the o ring can be seen in the pic to have snapped when the casing tried threading it into the threads during tightening). I’ve finally noticed this after unsuccessfully attempting to get the filter casing off by 1) using the plastic wrench, 2) using a second plastic wrench, 3) using PVC over the handle of one wrench as a lever (didn’t have wide enough PVC for two wrenches), and breaking the handle of that wrench, 4) hair dryer for several minutes, then hammer and mallet taps, then attempting with one plastic wrench, and finally 5) with a strap wrench (designed for oil filter) and ratchet, which didn’t work nearly as well (to get a baseline reference point for the tool) on my larger filter as the plastic wrench did - the larger filter can be loosened just fine. At this point do I just need to get someone to cut the copper pipes and install a whole new water filter, or is there any hope of getting this off while the o ring is between the casing and base, making it so hard to loosen? It’s not worked its way up into the threads, as can be seen in the picture, but it’s clearly at the base of the threads under the casing, not seated where it should be
