anyone know what this is? make/model

That is not a clickable link.

ugh. you can't see the picture?

I see the picture and the link also shows the picture again. Here it is again.

Thanks Diehard. Not sure why it was not click able for me.

That appears to me to be a Moen. As far as I know, the model number doesn't matter, since they all use the same cartridge. The only difference is whether it is a Posi-Temp valve (you rotate the handle to turn the water on and off) or a Moen-Trol valve (you have to pull or push the handle to turn the water on or off).

I am not sure what your issue is, but Moen has a lifetime guarantee. If you need a new cartridge or other parts, call their tech support people, and they will mail you what you need. Usually at my door 3 or 4 days later.

Thanks for the replies! Briefly - this was in the wall when we bought the house - i think it was supposed to be a small shower type thing for washing a dog. The room its in is off the garage and was unfinished. I have just gotten around to finishing it and realized the parts i thought were for this hardware actually are not. But it helps you think this is Moen because the parts i have are Grohe and nothing in the instructions looks like whats in the wall. So that helps

Thanks I will start looking at Moen products and see if i can find something that works.

That’s a moen 1222B cartridge

There’s two different cartridges for their showers. 1222B for the posi-temp and 1225B for the older shower controls and most basins.

As already mentioned, that is a Moen PosiTemp valve. Any PosiTemp trim you find will work on it.

Were I you, I would be curious as to what that odd buildup on the cold connection is.
