I could not fill my bathtub as the trip lever wouldn't work. I removed the face plate and tried to remove the old linkage assembly. While trying to pull it out it broke off at the hook on the bottom and the weight is now stuck in there. Is there any way to get it out or do I have to remove the whole tub? If I have to remove the tub I might as well as replace it. Where can I find instructions on how to do that? I am not the handiest. This is a first floor bathtub with a slab bottom. HELP!
