I used this sprayer for weeds. It has only been used 10 times and I have to throw it away. The valve broke after 4 uses and was replaced by the manufacturer. Now, the pump is broken rendering the unit unusable. It is really a piece of junk - not well constructed. I had to purchase two hose clamps early in it's life to keep the hose on during use. The manufacturer did not even think of suppling these hose clamps. We have a Chapin sprayer used for many years. We will replace this one with another Chapin.
