Pressure Compensating Shrubbler

Achieve flawless, uniform watering across your entire garden—from the highest point of a slope to the very last plant in a long container row. The Dripworks Pressure Compensating (PC) Shrubbler is the definitive solution for inconsistent water flow, delivering a precise, gentle 360° spray pattern to every plant, every time. Eliminate dry spots and waterlogged roots for good.

Why Choose the PC Shrubbler Drip Emitter?

• Guaranteed Uniform Watering on Any Terrain: Our advanced pressure-compensating mechanism features a durable internal silicone diaphragm that ensures a consistent flow rate (from 6.6 to 10.1 GPH) across a wide pressure range (15-45 PSI). This means the first plant on your line receives the same amount of water as the last, even on steep hillsides or in systems with long tubing runs, solving the most common cause of uneven plant growth.
• Protect Delicate Plants and Prevent Soil Erosion: The Shrubbler delivers a gentle, full-circle stream of water, not a harsh, erosive jet. This 360-degree pattern is ideal for watering shrubs, flower beds, ground cover, and container plants without disturbing mulch or washing away precious topsoil, promoting healthier root systems.
• Effortless Cleaning and Maintenance: Unlike sealed emitters that must be discarded when clogged, the Shrubbler easily twists apart for quick inspection and cleaning. This simple, take-apart design ensures a long and reliable service life, providing exceptional value and performance, especially in areas with hard water or potential debris.
• Built to Last in Direct Sunlight: Constructed from high-impact, UV-stabilized polypropylene, these emitters are engineered to withstand the harshest sun and weather conditions without becoming brittle or degrading. This robust construction guarantees years of dependable performance in your garden.

Ideal Applications

The Ultimate Solution for Sloped & Uneven Gardens

Watering a garden on a slope presents a unique challenge: gravity. In a standard drip system, gravity increases water pressure at lower elevations, causing emitters at the bottom of the hill to release far more water than those at the top. The Pressure Compensating Shrubbler's patented internal diaphragm technology (US Patent 8662414) actively counteracts this effect. It automatically regulates flow, ensuring every plant across the entire slope receives a consistent and correct amount of water. For maximum effectiveness, install your supply tubing laterally, running it perpendicular to the slope rather than straight up or down.

Achieve Perfect Watering in Pots, Planters & Containers

Container gardening requires precision. The PC Shrubbler is the ideal emitter for pots, planter boxes, and hanging baskets of all sizes. Its pressure-compensating feature is critical for systems using long lengths of 1/4" micro-tubing, where pressure naturally decreases along the line. The Shrubbler ensures the last container in the series is watered just as thoroughly as the first. Furthermore, its gentle, 360° spray pattern soaks the soil without causing compaction or splashing soil out of the pot, which is essential for maintaining healthy container environments.
