Mixing Valve Replacement

stepheng · August 2021

Has anyone replaced the LK550 mixing valve with one made in the US? I have not been able to find a domestic supplier for the repair kit that replaces the internal parts so that the housing does not have to be removed. There are several US manufacturers - Honeywell, Watts, etc. Any one using one of these?

Hi Stepheng,
I am looking for the repair kit for the LK 550 mixing valve as well.
What did you end up doing to solve/repair your faulty mixing valve situation?
Thanks!

Turns out it just needed adjusting. I couldn't find the repair kit. Only US distributor wanted me to buy a minimum order of $500 or so. Maybe its better now. I did look at replacing and found the new Alde valve in the UK at https://www.leisureshopdirect.com/gas/water/alde-water-heaters/alde-tmv3-thermostatic-mixer-valve. Taco makes ones here in the US - would require a little modification but would be worth it to have one with parts readily available in the US.

@stepheng Nucamp most likely has the part, or can get it for you without doing the "minimum" parts dance.

This is the link to Missouri Teardrops, who can order the part. (Hopefully!). Follow their directions on a photo and your VIN number. They will check availability, etc, and order the part. Shipped to your door.

@stepheng - Glad you were able to fix the issue with just an adjustment!
@pthomas745 - I will check into ordering the part through Missouri Teardrops. Fingers crossed!
Thank you both for the info!
