My mom's townhome has a jacuzzi tub with shower. The hot and cold are separate valves mounted on the flat shoulder of the tub, along with the tub faucet and diverter valve. The tub has gone a very long time without being used so the diverter, to turn it from shower to tub faucet, has frozen in position. I didn't want to force it so I turned the water lines off at the angle stops and started taking the diverter apart. After taking the handle off I saw that I could put a socket on what was underneath so I unscrewed whatever that thing is. Please see pictures to see what I'm talking about.
I couldn't figure out what I needed to do next in order to fix this frozen valve so I put that thing I had unscrewed back in and put the handle on and tried to work it back and forth gently to loosen it up. I wasn't gentle enough. The ribbed stub that sticks up upon which you fit the handle gave way, coming completely off. I wasn't sure which way it needed to turn in order to get to the tub faucet position so as I was turning it back and forth I obviously exerted too much torque in the wrong direction. I think it's pretty crappy (soft) metal as well, although it's over twenty years old so maybe these fittings corrode internally.
Would someone please identify just what it is I've got? None of the fittings have any obvious markings showing what brand they are - I'm hoping it is a standard or easily found valve. I imagine I'll have to buy a completely new diverter valve just to get the part that I've ruined by twisting it off. But perhaps if I know who makes the valve I could order just the part that I unscrewed?
Finding a replacement part won't solve the problem of the frozen valve but it will at least get me back to zero. From the pictures, it appears there is a hex-shaped fitting in the pipe that's sticking up. There's water in the pipe so that fitting is hard to see. Is that something I should put a socket on and twist?
I sure hope I don't have to do anything with the valve body itself as it is located in an impossible to access position.
Thanks for any help.
