I have a home built in 1968. In one shower there is a Symons Model "WO" faucet. I called Symons to order a replacement stem, etc and they had never heard of a Model WO. They actually asked me to take pictures of it and send it to them. Water leaks from the shower head and all I want to do is replace the washers or "o" rings, or the whole stem if necessary. I have done this on more modern Symons faucets and its a breeze, but I can't seem to find the parts for this Model "WO".
