    Hello,

    I recently purchased a house and quickly realized the master shower had no hot water. I had a plumber look at it and advised that the shower cartridge needed to be replaced. Here is where things get tricky. The shower does not have a shut off valve. I have emailed pictures of the installed cartridge to a number of plumbing supply store and no one can identify it and they want me to bring it in. If I turn off the water to the house and the cartridge breaks when I remove it, I believe I am screwed. Correct? Any thoughts on my next step?

    Thank you for your help

    It looks like it could be either of the cartridges below. It may be neither though. What I am unsure of it what retains it in the valve body. Thermostatic valves are usually threaded in, or have some sort of spring clip/trim that hold them in. Both of the cartridges that I found have a set screw in them (something I’ve never seen before). I imagine you screw it inward for removal, and screw it outward for installation? I found a YouTube video that shows the set screw being in the right side. The tilers didn’t do you any favors so you can’t access the integral stops(something I have encountered a lot before). Although I usually avoid using integral stops when I can anyway. As long as you find what holds it into the valve, I’ve never damaged this type of valve irreparably.

    Thank you Kevin. I think I have to remove the cartridge. there is set screw at the bottom. I wonder if there is a way to removr it without cutting the tile. The screw sit just above the tile opening. Very tight fit

    Have a nice evening

    If it’s an Allen screw, you may be able to cut an L shaped key down to get it to fit. If that doesn’t work, it looks like you’ll need to cut some tile away. Depending on how steady your hands are, a dremel, or an oscillating tool will work. You may want to call a tiler to do this for you though if you’ve never done it before.
