The sellers of the house we now own hired a terrible plumber to fix the plumbing issues in our soon-to-be home. For example, left a water leak (either caused by him or ignored) at the valve in the front yard leaking. A lucky discovery, we found it just two weeks after we closed. Anyway, on to the shower issue.
I'm no plumber, but it looks to me like when this guy "fixed" the whistling noise from the shower (hard water buildup no doubt) he replaced some parts there were not compatible with the old stuff, but put it back on anyway. What I'm left with is what looks like a cartridge that does not match the handle of the shower- thus I can get it to work so that the water turns on but the temperature adjust does not work. I could be wrong though- attached are pictures.
I'd like to know if I'm wrong, first off. But if not, I'd like to know how to figure out what faucet would be compatible with this valve so I can replace it.
That's what it looks like. I can't figure out how to remove any more of it from there. All I know is that the faucet handle, at least, is a Delta.
Now, the reason I think the handle doesn't match the cartridge is that they do not line up flush (and I'm pretty sure they did before we bought the house). Also it wouldn't make sense, such a large gap. Any ideas why this would be other than an idiot plumber?
This is as far as it will go, the cartridge plastic stuff is too large to fit through the little gear hole on the handle.
