I'm new here, and I wanted to replace a washer in my bathtub fixture as it was dripping slowly for some time now. I removed the knob and trim bezel, it was very hard to get the knob off because I believe it's been on for about 30 years or more. The house was built I think in 1952 , and when I took off the knob and trim, I knew I had a problem because I've never seen a faucet like this one. In the past I have changed a washer in a bathtub fixture, and I have a set of those deep socket tools to unscrew the stem, however this one is different.
This valve appears to be a cast brass large round piece that protrudes out of the wall slightly, and has a brass nut on the end that unscrews . I took the brass nut off and I was going to insert one of the sockets and unscrew the stem, but the hole that is around the stem is only about a 5/8 diameter hole and if I look in there with a flashlight, the stem is very long, I'd say aout 4 inches, and there is no nut down inside there to unscrew, so I'm at a loss on how to change this washer. I tried to count the splines on the end of the stem, and I think I count 16 spines not positive as it's hard counting them when you need new glasses.
Can anyone tell me what brand this might be? There is no name on the fixture all it says on the shower pull up knob is Made in USA, pull up for shower. The handles look like American Standard, I enclosed a few pictures to help identify this fixture. Also if you know what it is, can you tell me how I get the stem and washer out? It would not surprise me if it takes a special washer, I have a few packs of assorted standard faucet washers, hopefully it uses a common flat washer like the one I did about a year ago for my brother.
Thanks in advance for any help and info on this fixture.
