Problem with foam brush on Jim Coleman stand

[slash007]

I have a Jim Coleman Super Saver and my foam brush has been putting out very thick soap lately. I checked and the I am able to adjust the air pressure any way I like, but my chemical doesn't seem to go above 15-20 psi not matter what I set the regulator at. I tried changing the regulator thinking that was the issue, but no change. What should I check next? It is hooked up to a motor with a procon pump. Is it possible the pump is the issue? I thought if it went out it wouldn't output anything at all, but I wasn't sure.

Thanks.

I have problems with mine but the air side is difficult to adjust. When I have low flow problems I crack the main line going to the procon and allow some fluid to flow through. Every once in a while mine seems to get airbound, once I crack it it bleesd off the air and works fine. What type of regulators does everyone use on these??? Mine seem to last a few months then begin to leak air/fluid!!

It sounds like your pump is going bad.

Does your procon have a bypass adjusting screw? Might be the culpret?

I did play with the adjusting screw and it seemed to help a little bit, but I still cannot get the pressure to go above 20psi on liquid.
The foam coming out is serviceable for now, but I would like to have it a little less foamy.

So your procon is the adjustable kind plus you have a regulator in line ahead of your solenoids? Can you take the regulator out of the equation and try setting the pressure by the adjusting screw on the pump? I would think this would tell you if the pump is bad.

I have a procon pump on my Tri-foam and I adjust pressure on the pump, no regulator in the system. Has worked fine for over 4 years and hasn't changed a bit. I have it set on 80 psi?

Where is the pressure gage located in the line? Just ahead of the solenoids? Also, Do you have needle valves that adjust flow to each bay?
