I am trying to remove this faucet to replace the cartridge. There is not a set screw and the cone shaped body unscrews with the handle staying stationary, revealing the cartridge. (I've already sacrificed one faucet by using a pipe wrench with no padding rendering the faucet useless) I have tried strap wrenches, non marring pliers, pipe wrench with a rag over jaws, etc. and nothing will grab the body because the shape and chrome finish. Anyone have any ideas? TIA
