I have read all the posts I could find on changing tub spouts but I can't even get mine off. We have been having trouble with it for quite some time and today the shower diverter actually came out and the little white plastic piece fell out too. I can see how it works but I can not get it back in. I thought I would just replace it since it is old. The pin looks bent. I have tried pulling and unscrewing the spout. I can not budge it. Any ideas?
