I have a new shower with a Kohler K-304-KS Rite-Temp pressure balancing valve. The water temperature seems to fluxuate too much. Has anyone used this valve before? Can I stop the valve from adjusting the water temperature for me?

I'm just replying until someone who knows comes along! If it's brand new, isn't there a warranty or something? Could you contanct Kohler and ask them? Sometimes info is available on the company web sites, or there might be a toll-free number you could call.
Yes, you were right on! I called Kohler and they sent out new parts for the valve. I put them in and it works fine now. Thanks for the suggestion. Now, I just have the noisy drain problem to fix. But I'm on it.
When I got notified I had a response to my post, I couldn't remember posting to your question--was a while ago. Glad it worked out and you got the help you needed. Reinforces my belief that Kohler is a good company!
Okay, now it seems the Kohler valve wasn't the problem. I put in the new valve parts. Same thing. The water will suddenly drop 10 degrees for 10 seconds and then return. I took apart the old valve and drilled a hole in the plastic body into the brass piston that moves with a change of pressure. I secured the piston with a screw and put the whole thing back together. It still varies the temperature.
Now, this shower is supplied with hot water from a Takagi TK-2 tankless water heater. I have that set at 180 degrees because I also have it supplying heat for baseboard heaters. (Not in use now, it's summer) The 180 degree water is moderated by a mixing valve to give 120 degree water for the sink, tub and shower. This valve also has a "thermostatic" function, so it could be that. Or, perhaps the Takagi TK-2 isn't all that steady. Anyone have experience with this?
Sorry, I can't help you. Maybe someone else has some ideas.
