Just curious what your guys recommended PSI is for everyday residential carpet? My TM was set at 350 when I got it, so that's what I have been using. I turned it up to 500psi today as I used my cx15, and when I had to switch back to my wand for some areas, I left it at 500 psi. I feel like I can do faster passes with the higher psi, also it seemed like I had more heat with the higher psi? Is that possible? So just curious what your thoughts are on PSI, other than I am going to use more water.

I stay around 350 to 400 but it all depends on how bad the carpet.

I'm using a prochem titanium wand, and I am guessing it has the stock jets in it. I will have to double check.

With the sapphire 570 and the devpro wand been running at 500 psi seems to do great with a nice dry pass

400 ish.
Yes higher PSI will bring the flow to the wand quicker and water should be hotter if you have decent heat off the mount. Higher the PSI ... increases overwetting backing.
Can also leave pressure marks if you go to high on cut pile.

Talking to my garage tech, he said his brother was a carpet cleaner for 35 years. Used nothing but Butler units. And his go to psi was 150-250. I was shocked.

Wow! 150-250 seems really low! How do you even get carpet clean at that low psi? Maybe he has some secret behind that low of pressure? I have 4 jets, but will have to check numbers on them.

So what makes a butler or a bane TM able to clean at that low of pressure that would work better than any other truckmount at a higher pressure? Or is that just there recomondation?

So will more psi use more water as well? will a 2 jet wand use more water than 1 jet, or a 4 jet wand use more water than 2? I guess it all goes back to what else you do in the cleaning process. Chem, heat agitation ect. and to what degree. Im thinking like a 10 ph pre spray and crb to agitate, you can rinse with 150 psi. No crb or agitation, then im thinking a higher psi and more heat. Agree? input appreciated.
