Mine is set at 500 psi and it never changes for carpet and upholstery. I turn it up to 1000 psi for t&g.

It depends a lot on what wand you are using. With my old prochem quad jet 400 psi was about right. With my current wand 500-700 psi works good depending on the carpet.

Cleaning carpet with more than 400 psi and we are likely getting the backing wet. True glue down carpet
obviously can't handle those high pressures but even a heavy residential nylon can be damaged with pressure
obove 400 psi. Some portables may be set at 500 psi but when you key the wand it goes down to 300 psi. To
a large extent this has to do with the jets we are using . The bigger jets cause the pressure to fall more than
smaller ones. With my CA Jaguar 6.6 I usually ran mine at 350 with two 11002 jets.

Hi, also need to keep in mind the size and length of the solution hose you are running. Long length runs drop psi at the tool alot!!
I think if you look at the hose to pressure chart at cat pumps site you will see what I mean. On 1/4" hose, for every 50' of run it looses at least 50 psi. As the hose length gets longer the drop in pressure and flow is more significant. We run a Butler with live reels on 1/4" line of 150'. I think the drop from the machine to the valve is something along the lines of about 180 psi or something near that. That is alot of pressure loss!

We run the butler at 500psi normally at the machine on a 15" 5 jet wand. It cleans great and has short dry times as well.

Just saying, need to keep things in perspective with pressures being ran.

Hope this helps.

There is a lot of talk of PSI, a lot of very smart comments and technicians out there, I am wondering if you guys feel psi is all that important when it come to dirty to the eye carpet, I only do residential, reason I ask is because I currently prespray heavily and crb the carpet for scrubbing and agitation and then clean with my 220 psi diaphragm pump which I tested psi at 150 psi with 2 jet wand 02 jets and zipper not sure exact psi due to 5 1.5 jets, but I do get good results, so is psi really all that important or is it the tool, chemical and agitation more important, I would like your guys thoughts on this
