I find that most of the glass that I clean is hydrophobic. It seems to be a pain to rinse thoroughly with pencil jets. Am I just whining or should I buy some fan jets for the nylon brush that came with my Gardiner pole?
I am also puzzled about the pressure. I have a pump box that I bought from WCR. I usually set it to about 30 or 35. The range is 0-100. I understand that I need to keep the pressure down to prevent spotting. But I just watched a video of a guy cleaning triple over single DH in about 1 minute each. He seemed to have pretty good flow too. It would take me several minutes for me to clean the same windows for them to come out spot free. What am I doing wrong that is causing me to take so long per window. I am basically working at the same speed or slower than using traditional “nose to the glass” method.
Jeff Brimble the master wfp man. He uses a hudson backpack at 88 ft awesome. This guy knows his stuff. His brush design is awesome. Jeff is right, you do not need lots of waterflow and you can rinse with brush on the glass. You are new to using the wfp and just like a squeegee it will come with practice. Pencil jets will work on hydrophobic just make sure you cover all the glass as the water like to stay away from the sides. And by the way that wfp at 88 ft is Jeffs design and no one has match him working that high up. Modular pole. Also Jeff anyway I can get some of your magic formula that changes the glass to hydrophilic
That gives me food for thought. I like the idea of more than 2 jets. I think I’ll add 2 to my setup. Well it does make sense to have the jets above the brush. I wonder why the manufacturers don’t make the brushes like that from the get go.
I will answer that question from a manufacture point of view. Jeff uses a backpack so water flow is low. Most wcers use city water pressure or pumps so these type jets are for sprinkler systems and may not handle the high psi. Jeff will correct me if I am wrong. The new brushes now have dual jets so you could run both the fan and pencil at the same time. Also with jets above the brush you run the risk of wetting the top frame under high psi. Jeffs design is very cool. You should see his rain water machine
