Handy man/someone with elbow grease or plumbing experience needed. Shower diverter valve stem is stuck. Initially, the knob, escutcheon, etc were all stuck and corroded. I have been able to remove everything after (many hours and several trips to Lowes for sprays, extractors, etc.) including the packing nut but cant get the stem itself. This is a 5 minute job if I can get the stem removed. Had a plumber out before being able to remove all of this and they quoted $175. Really cant afford $175 to have someone come and remove it in 20 seconds. I have the replacement diverter stem and can finish the job once the old one is removed, if need be. Small fee is doable but $175 is out of my range. Know anyone that can possibly assist?
