Sooooooo. I bought a blue 50 gallon barrel yesterday at the flea market for 10 bucks. Pretty happy about that. I attached it to a pallet I had and installed a water hose spout in the bottom. I was hoping to fill with water, water and fertilizer, or what have you. I wanted to make a gravity waterer for my garden and apple trees. Idea being to raise pallet up high with forks, attach 25 foot hose with a quarter shut off valve on the user end of the hose, go plant to plant and water. I am disappointed in gravity. Just not enough flow, would be out there all day. So my question, what kind of pump could I bolt to the pallet to fix my problem? Need a pump that won’t burn up while hose valve is closed. Would love to have specific examples, never done this before.
