superclean

MMI I wish you would have responded with the first paragraph of your last post to begin with. I was just frustrated b/c I have been so busy lately I don't have time to keep coming on here and answering questions. I put the thread up and was trying to get a response to my question quickly. The next thing I know I am the one being questioned and the thread was kind of getting off topic. Anyways thanks for the info on the acid. I don't use it much, but I had it on my trailer so I figured I would try it.

Thanks to all who answered my original question. No harm meant but.... I asked a question if you know the answer and want to share feel free. Don't turn around and ask me questions and then tell me what I need or how to do a job you have never seen. I asked a simple question if putting a smaller orifice on would back up the pump and harm it. Why did you need to know what I was cleaning to answer that? By the way the flooring has an anti slip surface and is in a commercial car detailing shop. This stuff was very thick and durable not someones epoxy painted garage floor. The grease and dirt was very tough to remove. I tried straight mariatic acid, a general degreaser, and some of their engine cleaner and all of them did absolutely nothing to it. It had to be blasted inch by inch at about 3000psi with 200 degree water. The flooring held up fine.

Cleaning epoxy flooring. My pressure is about 2800psi not 3500. If I can get it to 3500 at the gun I would be in good shape. Does anyone know if going down in orifice size would put back pressure on the pump and potentially harm it?

I have two identicle washers. Figured it out last night. I knew something was odd because when I pulled the trigger it was still bypassing a little water into the tank whereas my other washer doesn't. Also when pulling the trigger several times I was getting different pressure readings ranging from 800-2000psi. But the lines were not pulsating so I didn't think it was starving for water or have a clog in the lines. But I ran the problem down to a bad or clogged chemical injector.

I have a job tomorrow that I need more pressure for. I have a 3500psi at 5.6 gal unit. When adjusting the unloader I am at about 4000 in bypass and 2800 with trigger on. That is reading pressure at my gun with 100 ft. hose. I would like to bump the pressure up but I don't want it to go much higher than 4000 when in bypass mode. How can I raise it? Should I just get a smaller orifice. Would putting a smaller orifice damage the pump in any way?

Engine is good Unloader is good Pulled the pump head and did not see any obvious problems. Would you be able to see if the packing is bad or is it to hard to tell? I think I am going to just replace the packing and see.

Just pulled the 6 nuts and flushed them and it still does not work. Any other ideas?

I have a 18hp kohler with a general pump and I am only getting about half the pressure I should be. I pressure tested it and I am only at about 1300psi. It should be around 3000. I swaped unloaders with one that I know works. Also, checked the filter which is off of a tank. I did notice when I pull the trigger some of the water is still bypassing back into the tank. That is why I replaced the unloader. Anyways I guess it has to be something in the pump. I have never taken a pump apart so I really don't know where to start. The pump is a general 3500 by 5.6 I think it is model #ts2021. Any help is appreciated.
