Have any ideas on how I repair this dripping problem? I have an indication that I need to replace a washer or "O" ring, but don't know how to get to those pieces. Help

Hi Cavhookem

Without a model number I can only tell you that you need to remove the handle and trim plate from around the valve and then shut off the water supply to gain access to the inside of the valve. Once inside the valve you will find a cartridge and/or cup washer and springs that will need to be replaced. You can locate replacement parts at almost any home supply store or any local plumbing supply store.

Good luck!
