Pretty surprising thing happened to me Monday. I was trying to change the cartridge in my Delta Fossett handle in our shower Sunday night, because the handle was leaking. I could not get this retaining nut to budge. Tried turning it with channel locks and hitting it to loosen any build up or cement that might be holding it. But it would not turn no matter what. So I gave up and I sent Michele to Lowe’s to buy a strap wrench Monday. Well, when I got home from work and I went to put the strap wrench on the nut the nut just turned without any effort! I didn’t need the strap wrench. My infant could’ve taken it off. It shocked me. I still don’t know what happened. It’s like an angel came in the night and loosened it for me.
