Review on Superb Wrench Housing 20 Inch Filters by Paul Rosemark

I tried to remove my "frozen" Big Blue 22" filter housing with three different plastic wrenches: all three didn't work. One of them, the last one, has the handle broke off when I added a short pipe extension as recommended to increase leverage This metal key is the only one that worked True it can cut into the body plastic Well just lower it a bit or raise it a little bit to get a new handle and as I understand it next time don't screw the case in as tight as you can. Hand tighten plus a quarter turn with two hands. That's it. The water pressure will keep it from loosening moves / loosens I wish the metal on this wrench was a little thicker, but so far after trying other wrenches for a week it was this one with its metal handle and longer handle that allowed me to break the stranglehold of the plastic.
