Does the psi on a backpack sprayer affect the volume of liquid you can put down? Like the SP1 (70psi) compaired to the SP2 (180 psi). If I wanted to use multiple tips to spray lawns, would I be much better off with more psi?

In theory it takes more fluid to create more pressure.

Do a test with plain water and a measuring cup, because on the little back packs they can make higher psi action with the same gpm.
