Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
I purchased a new Model 3800 D from Tom Johnson RV last July and I have had problems with the hot water in the shower. When I turn the knob to increase the flow of hot water to the shower head the volume and pressure diminishes to the point that I don't even have any water at all. Does anyone else have any ideas about this problem? I have talked to Tom Johnson reps and I have also talked to Coach net with no results. Please share any ideas you might have.
do you have pressure with just the hot water on?..........I would check water filter system for dirty filters.....and would temporally bypass or remove the house water pressure regulator and see if that cures it...............sounds like you have low water pressure

I have great pressure on the cold water side but when I turn toward cold the pressure becomes less and less until I have no pressure when it approaches full hot water volume
If this is a single valve unit with only one knob ........your mixer inside the valve is possibly obstructed.....or the hot water shut off for the shower is obstructed..........if it is a single knob type ....if you could give me the brand name off the knob I can walk you thru the repair..............should be a delta or symmons type

Just had a brain fart!!!.........if you remove the knob you should be able to remove the backplate......once you do that the mixing manifold will be exsposed......either on the hot water side your left hand......or in the center will be a screw adjustment turn it all the way in and test......then back it out and test........this is the anti-scald adjustment
if you have been having this problem since new , the valve was never adjusted out of the box because they dont wet test in the factory........they test for leaks with air!!!.
