If you read the text under the movie clip, it was done at 375 PSI.
The test was performed by Tom Cermak (me) in my driveway...
I should turn up the heat, but I'm afraid the hose would not stand the heat... the video was done under the actual settings I clean with.
We are able to run dual wands and keep those temperatures with the
AT.
Mark is my brother and many people think we sound alike, even our parents used to get confused lol
