Hello: I'm trying to repair the hot, cold, and diverter valves on a shower/bath tub. I removed the screw holding the handle, but I couldn't pull the handle off. I purchased a 'handle puller,' but after a couple of turns it would slip off the handle. I even tried C-clamping the arms of the 'handle puller,' but again after a couple more forceful turns, the 'handle puller came off the handle. I have the same problem with all three handles. Any suggestions to get the handle off of the valves. Thanks!

On my addition the building inspector indicated the need to change the two handle mixing valve to a "anti scalding pressure balance type". In speaking with him today, he indicated there may be a device I can install in the riser between the mixing valve and the shower head, without changing out the valve and reworking all that copper. I chose the two handle valve to coordinate with the separate tub and vanity valves, rather than go with a single handle mixer valve. My Questions: Is there such a device that can be installed in the riser between the mixer valve and shower head? If so, where can I find it? Are there any negatives in choosing this option over the single handle valve? Thanks, Iggy. ;)
