Well, being as persistent as I am, I was bound and determined to get this darn thing out and I wanted to replace the entire piece since I had purchased it new.
I had tried the tap thread and bolt method that I saw on the internet (they make it look sooooo easy), but it did not work for me. The bolt went so far and would just continually turn, not catching anything it seemed.
Before I left for work this morning, I sprayed the entire insides of the cartridge with vinegar and it sat all day long. I decided to give it one more go when I got home so I tried the bolt again and got a hammer. I used the claw end to grab hold of the bolt and gently gave it a tug. I was so excited because the cartridge moved forward and with a little more effort, it was free.
Don't get too excited yet! When I pulled it out, I realized that the last maybe 3/4" of the darn cartridge had broken off and was still inside my pipe! Why me? LOL!
Anyway, I am about to go get ANOTHER cartridge puller and see if I can get that last tiny piece out and get this job done once and for all!
I'll be sure to let you know how it goes! Thanks for all of the help. I appreciate it more than you could know!
Anyone need any help picking out lottery numbers? LOL! I'm not exactly the LUCKIEST person I know!
