Senninger 3/4 Hose Thread Drip Irrigation Pressure Regulator, 25 PSI, Landscape Grade High Performance

Revised Content:

Irrigation systems often experience fluctuations in water pressure, leading to unwanted flow deviations and over- or under-watering. In nursery, home, and commercial landscape watering systems, pressures can fluctuate when zones cycle on or off, or due to elevation changes in the irrigation system. A water pressure regulator serves as an automatic valve, limiting higher pressures to a desired constant lower pressure. Maintaining the correct operating pressure is crucial for optimum droplet size and radius of throw. Despite being an essential part of any drip system, pressure regulators are often not included in drip irrigation kits.

It is advisable to pair the pressure regulator with a backflow preventer and keep extra units on hand for irrigation repair, replacement parts, or system expansion. Senninger pressure regulators are built to rigorous quality standards and are known worldwide for their reliable performance. These regulators are 100% water tested for accuracy and can be installed above or below ground, with no external metal parts for excellent corrosion resistance. The maximum flow path resists plugging, and they feature very low hysteresis and friction loss.

The PRLG (Pressure Regulator Landscape Grade) model maintains a constant outlet pressure of 25 PSI (1.72 bar) with a flow range between 0.5 - 7 GPM (114 - 1590 L/hr), making it ideal for installations requiring lower flows, such as solid set, drip line, soaker hose, and other low-pressure agriculture, residential, and commercial irrigation systems. Proper use of this low-flow water regulator helps maintain sprinkler or droplet flow, distribution uniformity, and the overall efficiency of an irrigation system. It also contributes to water and energy conservation, as well as extending the lifespan of sprinkler and drip systems in your garden or nursery.

This sturdy inline plastic water regulator can be installed above or below ground, with no external metal parts for excellent corrosion resistance. It works with any standard 3/4" outdoor faucet, hose bib, garden hose, water hose, sprinkler manifold, garden soaker hose, or home irrigation system.

When measuring the dynamic water pressure of this regulator, it is important not to screw a pressure gauge directly onto the end of the regulator, as this would block the flow of water and measure static pressure instead of dynamic pressure. To measure dynamic water pressure, attach a gauge at the end of your irrigation tubing line or use an inline gauge that allows water to flow unblocked through the regulator.
