Higher PSI

[R W]

Had a chat with Greenie yesterday about 2 1/2 hoses, and cleaning with the Ti wand. On some of the nastier jobs, I was pulling out the Steamway flood wand....it puts out a crap load of solution in a concentrated area, but the 1 1/2 tube restricts even the Genesis vacuum. With the Ti, I was running about 5-550 PSI, and the flow didn't seem to agitate the bad areas as well. He suggested, and I kicked up the PSI to about 750, and what a difference it made. What kind of PSI are you running, and with what wand and flow??


Oh....I run slotted or hybrid glides on both.

I run 700 - 800 Psi with a Greenhorn wand, 10 flow. 2 in all the Way from a no 4 blower. No in line filter. I'm using quite a bit of water (compared to my old setup - 400psi 06 flow pmf 802 wand) but most carpets are left only slightly damp to the touch. The Greenhorn easily out cleans any wand Ive ever used. Its a great wand.

RW are you using extensions and what size jets. Are your jets hitting the glide? i am concerned about over-wetting over 550 psi

 

[Supersucker]

I am at 500 psi with a Ti wand, 9 flow. Soon I will go to 12 flow at maybe 350-400 to keep from blasting water all the way to the backing, while having the option to crank it up to flush out urine & whatnot.

If they are too nasty, I find prescrub to be worth the time FWIW.

Wow thats weird. I had a tile job yesterday had my PSI up to 750. Forgot to turn it back down today for a carpet job. Carpets were lookin a little more pimped today. I have a Twand which is pimped by Greenie. I guess I will be leaving it at 700-750. It must have helped it was a 300 dollar job and he tipped me 50 more. I am finally gettin busy. I had a real shitty April and beginning of May. My customers must be getting their monopoly money back.

R.W. I run the same machine as you and same wand as you. I have it "Greenied" at 12 flow with a Hybrid glide. Most of the time I am at 500 psi and that is plenty just like you said. Once and awhile I will push it up to around 600.

when I worked for rainbow we cleaned at 1000psi, a little streaking but not too bad, next place I worked was about 600psi, now that I have my own biz I run about 450

I usually change it based on the job.

Anywhere from 500 - 800 with a 10 flow greenhorn. On the real nasties, not many of those, switch to the 15 flow at max psi. Then hook up water hose, because it goes fast.

I run at 500 but after reading this post I think I am gonna try cranking it up.

 

[floorguy]

600 with a 12 flow....

funny because on houses i was just thinking of dropping it back a little...

commercial noooo brainer, give me the high psi. baby..

 

[Al]

Generally its up @ 700 or so

 

[steve r]

160

 

[Brad_Smith]

Lol. I remember cleaning with a bane. Now 15 flow GH 450-700psi.

 

[Blue Monarch]

500 here. I can't get myself to speed up my strokes. Scared I'll soak 'em if I crank it up.

 

[Jim Martin]

same as Dirk..........but I am at about 450.......

I am in no hurry .....I do nice slow even strokes...

it is only a 1/4 inch fiber....

I'm glad Brian posted.

It's one of the most common questions I get on the phone each week, What press. to operate at?

I always say wouldn't you use less pressure on a 20oz. cheap apt. grade carpet than you would on an 80 oz. thick plush?

NOPE! I just pull the wand faster.




Just kidding.

 

[Greenie]

Also....operating pressure has a hell of a lot to do with the wand, If I was running a PMF 2 jet, 400psi would probably be my maximum, a prochem could easily run 200 psi more on the same carpet, and a GH 200 more above that, none of the above would over wet with a conscientious operator.


Now Under Dry is another question.

 

[Ron Werner]

I have 15 flow with a greenhorn, 50' 2", 50' 2.5", running about 500-600psi with moderate stroke. damp to the touch

 

[Mike Draper]

I usually run 225 PSI. Oh yea, I use a RV-360.
