Leaky tub faucet - unsure of brand and how to fix?
Hi all! I am having a little difficulty with my tub faucet. First off, I am not certain what brand it is because the handle is a generic replacement but I've thought that it might be a Moen. It is a single-handle, pull on/push off, left and right to control temp style with a teardrop shaped handle with the point of the teardrop facing up. I should also note that the house is 30+ years old and we've owned it for about 5 so the faucet could be anywhere from 5 to 30 years old.
My problem is that my faucet has a leak that has been getting progressively worse and is now a very steady drip. I thought this was something I could handle myself and I tried pulling the cartridge out of the wall. What came out was an approx 5 inch long metal bar about the diameter of a pencil that had some o-rings and brass washers on it. I'm thinking that is not a part that is supposed to come out as it had one of those expanding split washers holding it in. I changed the o-rings on the chance it might help and managed to get the rod back in and while everything works, the drip is the same - no improvement.
First question, how can I be sure what type of faucet I have since there are no markings? Second, does the large chrome escutcheon plate from the wall for access or is this something that can be done without removing it?
