that guy has a skullet
anyways that machine sucks!!! who the hell wants to worry about everytime they set the wand down to open up some bypass at the wand to keep the truckmount from turning into Chernobyl. better yet who wants to be in the driveway of a multimillion $ house cleaning upholstery and have to have a hose running water on the ground, that is hackish at best. a simple temperature solenoid will fix that, BTW after 6 years and 2k hours my prochems bypass solenoid has never been off my machine or worked on in any way, its called a water softner. if it ever does get stuck open I can still finish the job and fix it when I get home, a simple soak in descaler is all it takes, but the last time mine has seen the light of day was when it was assembled at the factory
