Trying to find a replacement for a ceramic disc stem cartridge for our shower, but have no clue who manufactured it. Was hoping someone could help identify it. BTW...I have no knowledge of plumbing. I'm trying to do the legwork for my husband who works a lot and hasn't had any luck from local hardware and plumbing outlets. I've attached a photo of it. Here are the specs as I understand them: ceramic discs, 16pt broach, approximately 5 1/2" long, 1" base width, 1/2" threaded neck. Any ideas? Thanks in advance for your insights!
