Uneven spray from a Hunter rotor is usually caused by clogged nozzles, damaged parts, or low water pressure. Dirt or debris can block the nozzle or filter screen, disrupting water flow, while worn gears or seals may prevent smooth rotation. Additionally, water pressure that is too high or too low can affect spray distance and uniformity. Try to fix your Hunter rotor by cleaning the nozzle, checking for worn parts, and ensuring your system uses the right amount of pressure. If the rotor is in especially poor condition, it may be in your best interest to shop for a replacement.
