Rain Bird Rain Bird 1804ap4 Pop-up Spray Head, Adjustable, 4-in. Pop Up, 4-ft. Spray

The Rain Bird 1800 Series is the world's #1 commercial-grade pop-up sprinkler head, installed in parks and backyards globally. This model is engineered for reliable underground irrigation in all climates and soil types, delivering water to shrubs, small lawns and irregularly shaped planting areas. The 1804AP4 combines heavy-duty materials with patented technology to ensure years of dependable service with minimal maintenance.

Pop-up sprinkler heads must withstand constant pressure changes, soil debris and harsh weather. The Rain Bird 1804AP4 solves these challenges with a patented co-molded wiper seal that actively clears debris when the unit retracts, plus a strong stainless steel internal spring that guarantees positive stem retraction and a tight seal season after season. This design prevents water leakage and keeps grit out of the case, extending the head's lifespan.

Features and Benefits

• Patented co-molded wiper seal: An encased plastic cage resists grit, pressure and environmental damage while wiping the stem clean at pop-down to prevent water loss.
• Heavy-duty stainless steel spring: Ensures dependable flush retraction every time, protecting the internal mechanism from soil and debris.
• 4-inch pop-up height: Modest rise protects the unit while delivering effective water coverage without being obtrusive.
• Adjustable spray pattern: Two-piece ratchet mechanism allows nozzle pattern alignment without tools, enabling directional adjustment after installation.
• Top-removable components: All sprinkler parts are removable from above without special tools, making flushing and maintenance quick and easy.
• Pressure-activated multi-function seal: Provides a positive seal without excess flow-by, allowing more heads on the same valve.
