Low PRessure is smooth, no pulsating or machine gunning which leads me to believe there are no air leaks. Thanks Russ......I do not use the machines on a daily basis and my employees fail to communicate frequently, but I would guess it has been Fading.

Mine was a gun on my surface cleaner that died 6 ft into the job. Left pressure on the line and everything.

Nervermind.

Just reading down the page and thought the same thing, all I can say is WOW, I'm glad that place is helping mike find out what was wrong with it. Say that site might be $5 or $10 cheaper? Do you think that they would give out as much help as russ does without charging anyone? Or think if mike would have taken the machine to the shop what a big charge he would have gotten from that!

thanks russ for helping me out more than once before and for helping others out!
 
I had it happen to me today too. My relief valve was sucking air. Took me 40 minutes to figure it out.
