content: I attempted to spray a fungicide on my lawn with this sprayer. After spraying for about 20 minutes I realized that the product was not being drawn up into the hose spray. I checked the tubing, attempted to push it on tighter etc. I then sprayed an area approx 4 square feet. All of the product was deposited into this area in less than 1 minute. So now I have a small section of lawn that is extremely overtreated and the rest untreated. So I am now watering that area for the next hour in an attempt to dilute the product and not further harm my lawn. So I am out the product, watering for 1 hour, and my time! Very annoyed!
