Rain Bird PRS05030S 30 PSI Retrofit Pressure Regulator for 1/2 Inch Threaded Riser

Effortless conversion to drip irrigation

Rain Bird PRS05030S offers a compact, durable way to transform a standard 1/2 inch riser or shrub spray into a precise low-volume drip zone. Regulating flow at 30 psi, this regulator helps micro-watering devices perform with consistency while supporting water-conscious lawn and garden practices. The result is a more targeted application that can reduce waste and improve plant health in dry periods without forcing dramatic changes to your outdoor routine.

Key connections are simple: a 1/2 inch FPT bottom inlet and a 1/2 inch MPT top outlet that accepts a drip manifold (sold separately). When paired with Rain Bird free flow manifolds, you can create flexible emitter networks that feed 1/4 inch drip tubing to emitters, bubblers, micro-sprays, and 1/4 inch emitter tubing. The setup is well suited for retrofit projects where you want to add or expand a drip zone without a full irrigation overhaul.

Durability and installation in the real world

Made from UV and chemical-resistant materials, the regulator is built to withstand outdoor exposure, from hot sun to garden soil, for longer life in residential borders, shrub beds, and landscaped beds. The unit is designed for quick, tool-light installation on existing risers, enabling a clean, integrated look while supporting an efficient watering strategy.
