Have you ever wondered what it is like to clean a composition roof at three stories above the ground?  Watch this video and you will see and feel what it is like.  Many more to come as the videos are edited.  Note the trigger gun used is a 12 gpm SS Suttner ST2700 and has been used for 3 years with no problem.  Many here have doubted that it would hold up.  Well it has and will save you from using to much roof cleaning chemicals and it has a feather trigger.  Yes it costs more than a PVC valve but it will save you time and money

 Looks great Marcus! BTW, how much "mileage" do you have on your pentaflex?  I know most use fatboys and only a few of us have the pentaflex and wondering how long it holds up to continuous usage?

 I do not continuously my pentaflex pump as 20% of my businiess is roof cleaning.  Most roofs that I clean are tile and about 6000 sq ft.  They take about 4-6 hrs to clean.  In that definition of continuous usage the pump runs for about 6 hours using a 30 dia nozzle and the pump continuously cycles.  The pentaflex seams to have a better limit switch as I have yet after 5 years of using this pentaflex had to change a limit switch.  I did have to change a pumo head after running CH  through it as the CH residue gummed the valves up.
