Sprinkler heads come in different types:
- Pop-up spray heads: Short and spray water in a fixed pattern.
- Rotary heads: Taller and rotate to cover large areas.
- Drip emitters: Deliver water slowly near plants.
Mark each head location on a map or paper. This helps when adjusting or fixing them later. Check for any heads that are cloggedor damaged. Clear debris and make sure the water spray is even and covers the desired area.
