Can you help me find the right stem (or knob) for this 20-year old Symmons
Temptrol shower faucet?
My Symmons ModelÊ faucet stem broach splines are the wrong size! :(
* The shower faucet has a circular brass plate stamped "Symmons" "Model CA"
* Naturally I assumed it's a Symmons faucet so I called them for parts
* Symmons kindly sent beautifully machined parts; (almost) all fit nicely:
- The TA-10 Temptrol "spindle assembly" is a gorgeous work of art
- The TA-25B "black diverter spindle kit" was a 100% perfect replacement
- The TA-4 Temptrol "hot and cold seat kit" was likewise elegantly machined
- The TA-35A "cold seat removal tool" fit the larger cold seat perfectly
- The TA-35B "hot seat removal tool" likewise nicely fit the smaller seat
- Even the installation diagram & instructions were perfectly aligned with
what I have in my 20-year old shower faucet
The only problem is the faucet stem broach splines are the wrong size:
* The Symmons spline is circular, 12 point, ~0.415 inches in diameter
* My brass spline is circular, 16 point, ~0.360 inches in diameter
Have you run into this problem before?
How do you solve it?

Few plumbers can help you because you have a high end bathroom
It's probably made by Harden who would take Symmons Temptrol valves
and customize the stems making it longer, thinner, and with more
Your best bet is to throw it away because Harden went out of business
and I doubt you'll find such high end legacy replacement parts on the

I looked for Harden to no avail in the Master Plumber Bible:
When I called Symmons technical support a few weeks ago, they sent me the
"Symmons TA-10" shower faucet flow control spindle but I now realize they
should have sent me the Harden TA-10H flow control spindle which is a
modified Symmons valve not sold by Symmons anymore.
You can see the difference between the original Symmons and the Harden in
this web page which shows the Symmons TA-10 next to the Harden Symmons
TA-10H faucet valve.
Now that I know what to look for, hopefully I can find a Harden TA10H in
stock somewhere local.

Instead of looking for a valve stem to fit the faucet knob, why don't you

I think your numbers are wrong though. Looking at the URL, he needs the 12

I'm still stuck.
When I told Symmons customer support at 800-symmons that it was a harden
faucet stem, they said they can't help me anymore.
I sent photos to symmons customer support email@example.com who finally said
they have nothing that will fit.
So, now I'm stuck with a Symmons TA-10 stem (12 point, .415" broach) and I
need to find Symmons or other hardware to fit. Yet when I go to Home Depot
and ACE and OSH, all of them tell me is that I have to replace the entire
mechanism behind the wall!
There must be a simple solution out there. Are there any Internet savvy
plumbers on this message board?
