We have one of those faucets with one handle which first goes to cold and then progresses to hot as you go further from off. Or, at least, it used to be that way. We went on vacation, had someone staying in the house, and, weirdly, when we came back, the situation was reversed: it goes to hot right when opened up, and then to cold past that. What's more, hot is about 5% of the range right at the beginning, with most of the rest of the dial just being cold, cold, cold.

Our housesitter says she has no idea that anything happened, and that seems reasonable... but, for whatever reason, something must of have twisted inside, although I'm not sure what or how.

We've finally gotten tired of this and wanted to fix it. I contacted a plumber, and he said that they'd come, take a look, and then drive to the neighboring town to see if the plumbing supply has the right part — all on the clock. I don't want to argue about the business model there, but, really, we just can't afford the risk of an open-ended trip like that.


  1. Any idea what's going on?
  2. Is this something I can fix?
  3. If not, is there some way I can identify the part that might be needed, so that the plumber (or I!) could preorder and just bring the right part in the first place?

Here's a picture of the valve / cartridge:

There are no obvious model or serial numbers or any identifying parts.

Is it possible that the little plastic toothed parts are just slipped in some way? I didn't want to mess too much for fear of making things worse.

I think it's a Delta. See if this video helps you (especially around 1m20s) youtube.com/watch?v=XkanSw90Czw And don't be too fearful; those stems/valves are like $20 are a big box store. I watched a couple of videos and got real comfortable with the process and changed my Moen last week in about 10 minutes. – Ghost Oct 20 '13 at 18:21
I think your housesitter forced something or had people over to your house using your shower. – RockPaperLizard Nov 26 '14 at 7:31

It's actually a Danze. I had to replace mine as my hot water would not shut off. After alot of investigating and calling different suppliers ex: Moen and Delta, I was directed to Danze 1-800-487-8372. I sent them a picture of the cartridge and it was theirs.

Thanks! Too late for me (eventually had it replaced as part of a larger bathroom makeover), but possibly this will help someone else. – mattdm May 12 at 14:59

if it is a MOEN Faucet just remove the handle from the stem & turn the stem 180deg. & re-install the handle & all should be back to normal again ... Hope this cures it!

If it's a broken MOEN you get it for free. Lifetime guarantee on some, 5 year on others. – Mazura Sep 27 '14 at 5:54

I'm not a plumbing expert, but I installed a new cartridge in my shower and had this problem. I think a new cartridge was installed in your absence for some reason, and installed incorrectly. Should be an easy fix, shut off house water, take it out and rotate it 180° reinstall, turn water on, should work fine.

I'm certain a new cartridge was not installed in my absence — our housesitter had neither the knowledge to do that, nor the money to pay someone else to. And for that matter, I can't imagine a situation in which she would have done so. – mattdm Jul 16 '15 at 14:59
