I have a pump sprayer for Round-Up. It is from Ace Hardware, although I have had different brands. They only seem to last a year or so. The pump thing goes out. Today, I pumped it up, and it released all of the pressure. There is a pressure relief valve on the top, so I moved it backward, thinking it might have been left open. This had absolutely no effect.
Can this sprayer be saved? I'm tired of buying new ones. Also, I want to spray my wild morning glories TODAY, before it has a chance to rain again.
