I have a ~15 year old Delta single-handle anti-scald shower valve in one of my bathrooms that occasionally only flows HOT. I replaced the compensation valve several years ago and I guess I need to again. The problem is I can't find the manual now--so no part number.
I'm hoping there's only one choice in replacement cartridge(?)
Taking it apart beforehand is a problem due to distance from stores & my availability so taking the old one with me isn't my first choice--but if that's what has to happen I can deal with it.

 

Have you visited the Delta website? They have a faucet identifier. You can also call their tech support number.

 

Agreed call Delta, they have good customer service and will ship you the parts for free.

 

Looks like I'm not going to the hardware today.
The part identifier didn't work. On my desktop it doesn't respond to any choices & on my phone it starts out filtering for "repair parts" but ends up only showing *new* parts for current models.

I called and was surprised it's covered by a lifetime warranty. I just need to take it apart far enough to describe details such as screw positions so I'll do it from home.

This might explain why I can remember installing a new valve but not how I found it. Pity their records don't go back far enough to find my call from years ago.

See the link above to insert pictures. Someone here might be able to identify the valve. Each one is unique in some way.

 

Well the joke's on me. I was on the phone with Delta and she said send me a picture. She got it and..."that's not one of ours".
Why would Price Pfister put a greek "Delta" triangle symbol on the knob?
