Drip/Low volume irrigation systems operate at much lower pressures than sprinkler systems, and so a pressure regulator is usually required to bring the dynamic pressure down to an acceptable range, normally between 15 and 35 psi. A drip system that operates at high pressure (above 40 psi) may appear to be operating adequately; however, it is more likely to develop problems over time.
The most common pressure regulators designed for drip irrigation systems are non-direct acting pressure regulators that have a pre-set output— they are not adjustable. These regulators are not suitable for continuous pressure applications; that is, they must be installed do
