My sg 20 stihl backpack sprayer is loosing pressure
Happy new year guys. About 2 months after I bought my sprayer it started lousing pressure. I have to pump like a mad man to get through one job. Initially the sprayer was like a dream, and pressure was not a problem. Any body have an idea where to look? I looked at the take-up pipe and check valve for clogging. I hear no bubbling, or can feel no sudden loss of pressure. I know I can take it back to the dealer and get it fixed, but I don't want to give it up for a couple of days.
