Our shower head has started leaking. I have checked the head itself and the tape is good, as well as the washers. The leak is not coming from the point where the head connects to the pipe, so I am pretty sure it has something to do with the valves in the handles. I took the shower head off and the drip is still coming from the end of the pipe. The plumbing in this house is pretty old and I am not sure how to replace the "cartridge" if that is even how these are set up. I would like to replace the knobs and everything if the problem is actually coming from the valves. Should any shower set from home depot fit? If not, how do I know what will? I can take pictures if it would help with advice on what to do.
Thanks for the help in advance.
