rebuild/replace element in vernet thermostatic valve

Author: ingenthr (CA)

For the second time in about 6 years, my Altmans (out of business) thermostatic valve cartridge (HFCART2) seems to have failed. It never comes up to the right level of heat.

Question: is there a vendor who would, or is it somehow possible to, replace the thermostatic element on it?

I kept the other failed valve thinking that maybe I'd look into this if it ever failed again in the future. I didn't expect it to happen so soon. The thermostatic element itself is made by Vernet, it would seem.

Thanks much for all of the past help too!

Author: marlinman (FL) Try soaking your cartridge in white vinegar for a hour. Then flush the cartridge alternating from full hot to full cold for 2-3 minutes. do this 5 or so times. Apply ONLY silicone grease to the seals and reinstall. For what its worth the HFCART is not Vernet. Their Vernet they used is C9VERCART in 1/2" valves only.

Thanks for the advice!

On the back side of the cartridge, I see Vernet stamped in. You can see it a bit in the image[1] and I took a better pic once before so I could zoom in to see it.

Also, I added a water softener before I last replaced the valve, so I don't think it'd be from hard water stuck in it. And, I did use a silicon grease when installing.

I will give it a shot and will cycle it as you recommend after a thorough cleaning. Hopefully this gets it going. Thanks!
