Filter/Pressure Regulator Unit

The Easiest Way to Convert Your Sprinkler System to Drip Irrigation.

The NDS Filter/Pressure Regulator Unit (SKU: FPR17) is a compact, all-in-one sprinkler-to-drip conversion fitting designed to thread directly onto a standard 1/2″ MPT riser — replacing virtually any pop-up spray head from any major manufacturer. In one simple swap, you eliminate the high-output spray head and gain a properly filtered, pressure-regulated starting point for a drip irrigation zone.

At the heart of this unit is a built-in 30 PSI pressure regulator that steps your system pressure down to drip-compatible levels, protecting emitters and dripline from pressure fluctuations that cause uneven watering or premature failure. A removable 150-mesh screen filter catches particulates before they reach your emitters, keeping the system running cleanly without a separate inline filter. The unit passes up to 300 GPH and accepts up to 60 PSI at the inlet.

Two Smart Loc™ swivel outlets on the universal adapter connect to multiple sizes of poly tubing and dripline. The outlets rotate a full 360°, preventing kinking or bending as you route tubing in any direction. An included end cap lets you close off one outlet if your layout only requires a single run. The filter/regulator body and adapter are constructed of ABS; the filter screen and mesh are polypropylene for corrosion resistance.

This unit is the same component at the core of DripWorks’ full Sprinkler-to-Drip Conversion Kits. If you’re converting multiple heads, you can also pair it with our poly tubing and drip emitters to build out each zone affordably head by head.
