I'd like to replace the old Harden tub/shower valve trim in my condo's bathroom. As far as I know the Harden company (which already went bankrupt) only made trims and they used Symmons hardware under (i.e. valve, etc.). I'd like to put a newer Symmons trim on (e.g. S-6700TS-TRM ). My issue is I can't take the knob off from the shaft. I tried to use strap wrench for that but it wasn't successful, maybe I needed to put more force but I'm not sure...
