Orbit 38091 Pvc Riser 0.5 X 12 Inch Irrigation

Product Description

The ORBIT IRRIGATION PRODUCTS INC 38091 is a 1/2-inch by 12-inch PVC riser designed to extend sprinkler heads above grade in residential and commercial irrigation systems. This threaded riser connects standard sprinkler heads to lateral supply lines, providing the vertical offset needed for proper head-to-head coverage or to clear low ground cover and turf. Constructed from PVC, the riser is lightweight, corrosion-resistant, and well-suited for burial in soil environments. Landscape contractors, irrigation technicians, and experienced DIYers install these risers during new system layout or when retrofitting existing zones to adjust spray height.

This riser is used in underground lawn and landscape irrigation systems where a fixed 12-inch vertical extension is required. Typical applications include turf zones, planter beds, and ground-cover areas where sprinkler heads need elevation above plant material or sloped terrain. The 1/2-inch pipe diameter matches the most common lateral line sizing in residential irrigation layouts, making it a straightforward fit for new installations and repairs alike.

Key Features

• 1/2-inch threaded connection compatible with standard irrigation fittings and sprinkler heads
• 12-inch length provides fixed vertical extension for proper spray clearance
• PVC construction resists corrosion and moisture degradation in buried applications
• Lightweight at 0.17 pounds, reducing handling fatigue on large zone installations
• Sold individually, allowing precise quantity ordering for zone-by-zone repairs

Compatibility

Designed as a standard OEM-style replacement and new-installation component for residential and light commercial irrigation systems using 1/2-inch threaded sprinkler heads and lateral fittings.

Installation Notes

Installation is typically performed by licensed irrigation contractors or landscape professionals. Shut off the irrigation zone valve and relieve line pressure before disassembling any fittings. Use Teflon thread tape on all threaded connections to ensure a watertight seal and prevent joint weeping under system pressure. Follow local plumbing and irrigation codes for burial depth and backflow prevention requirements.
