Chicmount 4" Pop-Up Sprinkler Heads 8-Pack — 1800 Series Compatible, Adjustable 9–20 ft Radius

Chicmount 8 Pack 4 Inch Pop up Sprinkler Heads compatible with the 1800 series are compact, adjustable irrigation nozzles that pop flush with the lawn and deliver a 9–20 ft spray radius for small to medium landscapes.

These replacement sprinkler heads are made from durable plastic and designed to integrate with 1800-series systems, offering easy installation and tool-free adjustments so you can tailor spray distance and arc to irregular lawns, flower beds, or community green spaces. With a 4-inch pop-up height, the heads stay hidden when inactive and pop up to distribute water evenly, helping maintain tidy turf edges and unobstructed mowing.

How do these pop-up sprinklers fit into an existing 1800 series system?

The Chicmount heads are built to be compatible with 1800-series sprinklers and use standard bonnet and valve-body dimensions for straightforward swaps. Replacing a worn head only requires removing the old unit and screwing in the new one, with no specialized tools needed.

• Standard 4" pop-up height suited for 1800-series in-ground lines
• Threading and bonnet size match common 1800-style fittings
• Designed for quick unscrew-and-replace maintenance

What adjustments can I make to the spray pattern and range?

You can set the spray arc anywhere from 0° to 360° by twisting the nozzle, and the spray radius is adjustable between roughly 9 and 20 feet to suit various plantings. These controls let you reduce overspray onto sidewalks or focus water into denser planting zones without swapping parts.

• Arc adjustment: full-range 0–360° rotation for custom coverage
• Radius control: adjustable spray reach from about 9 to 20 ft
• No tools required — twist to set arc and distance

How simple is maintenance and nozzle replacement?

The heads were designed for user-friendly upkeep: unscrew the bonnet, pull out the valve body, compress the spring and access the nozzle for a swap or cleaning. Nozzle interchangeability allows different spray patterns for seasonal needs or changing landscapes.

• Bonnet removal exposes valve body for quick access
• Spring-compression design simplifies nozzle swaps
• Replace or clean nozzle without digging or special tools

What kind of coverage and applications are best for these sprinkler heads?

With a broad adjustable radius and 4-inch pop-up profile, these heads work well for residential lawns, medium-sized gardens, and commercial landscaping that use 1800-style systems. They’re particularly suited to areas where flush installation and unobstructed lawn use are priorities.

• Ideal for front yards, backyard lawns, and small community green spaces
• Useful around walkways and mowing zones because they retract flush
• Adjustable spread adapts to both circular and sector-shaped beds

Who is this for: homeowners, landscapers, and groundskeepers using 1800-series irrigation systems who want a cost-effective set of replacement or upgrade heads. If you need low-profile pop-up units that are easy to install, adjust without tools, and cover small-to-medium areas with flexible spray patterns, this 8-pack from Chicmount provides spare parts and quick fixes for routine irrigation maintenance.
