As grass grows or soil settles, sprinkler heads can become recessed ? leading to poor coverage, dry spots, or turf damage from mower blades. This riser solves that by allowing precise height adjustment to keep heads flush with the surface. Its cut-to-fit design eliminates guesswork and reduces the need for multiple fittings, while its UV-resistant material ensures durability whether installed above or below grade. A small but essential component that enhances system efficiency, extends equipment life, and keeps landscapes lush and evenly watered.
