I’m having serious issues replacing an antique faucet stem on old old claw foot tub.

The hot water nozzle slowly leaks and I can’t find a replacement stem or even a washer that would fit. I emailed Faucet Parts Plus and they replied we have nothing that matches. Does anyone have any suggestions?

The picture is the cold water cartridge which is the one that works. I need a hot water cartridge/stem. (It looks as though it was cobbled together with a different washer to slow the leak) 12 spline.

Cartridge and washer

  • I would recommend taking it to a local plumbing supply house (not a big-box, home improvement store). The odds are good that they'll be able to find you a part that will work. They may have to order it, but they're the ones with experience and calipers to take all the required measurements.

Most hardware stores will be able to find a match. Bring the stem with you. There are usually many replacements in stock. If not the usually have a plumbing parts book or software they can look up the specifications and then special order it for you. It may be helpful to take a picture of the faucet if they want more information.
