Does anyone know the manufacturer and model number for the shower valves Newmar uses in the Dutch Star? I attached a few pictures of the shower valve in question.
My 2016 DSDP 4369 today had an issue with the shower valve where I get full flow with cold water as I open the valve, but as I turn the lever to increase the water temperature, I get a "thunk" (technical term) and the shower output slows from full flow to a trickle. Full flow returns when I turn the valve back to cold water. Not sure what is going on. I have no issues with hot water flow in any of the other faucets in the coach.
I'm hesitant to take the valve apart any further without knowing who manufactures it and where I can get repair/replacement parts. I didn't see any isolation valves for the shower so I need to have parts on hand before I take it apart.
I sent Newmar an email earlier today, but don't expect to hear back from them before next week.
Any input is appreciated.

I had the exact same issue on my 2017 DS. It turned out to be hard water deposits on the hot water check valve on the shower valve. Those two screws with stop nuts to the left and right are combined shutoff valves and back flow valves. Loosen the nuts and back out the screws to remove them. you will see that they are binding up with calcium deposits. soak them in a little CLR to clean them and then reinstall them.
By the way, the valve is Rough in Valve Huntington Brass #05120-00. The ceramic disk cartridge is # ST7100.
Don't forget to shut the water off and release the pressure before you start to disassemble the valve.

Thank you! This is the information I was looking for. Looks like I’ll be working on a shower valve this weekend.

Thanks to Aweese for the information. Problem solved! The hot water service stop was plugged and needed cleaning. See photo.
I also went to the Huntington Brass website and downloaded the spec for the shower valve. PDF attached.
The only caution I would provide is to be careful removing the service stops. They contain a plunger and spring. If you drop any of these parts into the shower wall opening, they are gone forever.

This is what my service stops look like. I have cleaned them and have a new cartridge and still have the exact same problem. See photo.
Cold water flow in the shower only, is finally fixed

Even though my check valves look different than others posted, they work the same. The part that goes into the part with the spring was totally stuck with deposits. I finally carefully got them apart and cleaned them well. My problem is solved. Hard water for sure was the culprit.

Would you be willing to walk me through the process over the phone? I’m afraid to start pulling things apart without some guidance. Thanks!

I have the same issue. I found the opening for the set screw on the bottom of the handle but can't get the Allen wrench on the screw. How did u find it?

To access the recessed allen screw on many faucets, you must move the handle/open it some.
So, turn off shore water, turn off water pump and open a faucet to bleed off pressure.

Sometimes you have to get a set of really long allen wrenches, so they flex a little. This was a timely post by "ftharrisiii" as it shows the adjusters, I was telling you about.
