It’s a German design, very high-end, but not so common in Utah. This was the first one I’ve ever encountered, and looking online for more information led to not many results, so it felt important to document how this valve works and comes apart.\n\nWhat made it interesting is that this valve does not operate like most. It has the temperature controller before the shower shut-off valve. We initially believed it to be the thermostatic cartridge contributing to the problem. Once we got into it, another issue showed up: the little plastic plunger that controls the temperature when you turn the valve on and off was broken.\n\nWe later identified that was due to extremely high pressure at the house. The pressure reducing valve had failed, leading that piece to break. For anyone curious how it comes off, that piece just spins right off the shaft. We weren’t able to complete the repair this time, but that’s OK. We will be back to change the pressure valve and finish this at a later date.\n\n**Job facts:** [Bathroom Plumbing & Fixture Repairs](<https://mtnmanplumbing.com/bathroom-plumbing-fixture-repairs/?agentnet=md>) in [Sandy](<https://mtnmanplumbing.com/?agentnet=md>), Utah.\n\n![Tyler Nerdin](<https://mtnmanplumbing.com/wp-content/uploads/2025/12/Tyler-Nerdin.png>)\n\nProject Lead\n\n### Crafted by Tyler Nerdin\n\nMaster Plumber   \\|   Lic. \\#8522119-5518\n\n[Learn More About Tyler](<https://mtnmanplumbing.com/tyler-nerdin/?agentnet=md>)\n\n```\n         Mountain Man Plumbing   79 Google reviews   Write a review                 Posted on Google        Liz      Trustindex verifies that the original source of the review is Google. Super helpful and informative. Communicated well and was punctual!         Posted on Google        Nathan      Trustindex verifies that the original source of the review is Google. Tyler from Mountain Man Plumbing replaced my in-house main water shutoff valve and the pressure reducing valve (PRV) with a very practical new system that enables me to view the line pressure coming in and any drops in pressure easily. Very good looking workmanship.\n\nPrior to the work Tyler came out to my home and provided an estimate on the work, and stuck to the estimate. He's been easy to work with, cleaned up after himself, and also allowed me to change an appointment close to my originally planned estimate appointment over the phone. The website is also easy to use and efficient for scheduling an estimate. Thank you!

Tyler showed up right on time, was professional, and got everything taken care of faster than expected—finishing the entire job in less than a day. He replaced our water heater, took care of the valves, and installed a new expansion tank, all with great attention to detail.\n\nEverything is working perfectly now, and the whole process was smooth and stress-free. Highly recommend Tyler and the team if you’re looking for reliable, efficient plumbing work!         Posted on Google        Dana      Trustindex verifies that the original source of the review is Google. Tyler was very professional, polite and honest. Instead of trying to sell me new parts or a whole new water heater he showed me that some of the heating elements just needed cleaned. I would recommend this company for anyone looking for honest help to get the right fix without getting ripped off.

Hard to find a plumber who preps for a service call like he did.  He asked questions before he came over to fix a shower valve so he could make sure he had the right parts for the fixture so he was as efficient as possible when he got here.   Communication was great prior to the service call and during.  Fixed everything I needed in a couple of hours for a very reasonable price.
