Netafim WPCJ CNL Dripper, 1.0 GPH, Nipple Outlet
A small bag of drippers is the quickest way to rebuild a few stations or test a layout before a full planting. This bag holds 25 Netafim Woodpecker Junior drippers, item 21520-001510, model 01WPCJL4N-B25. Each is grey with a black outlet, the color code for a nominal 1.06 GPH. The dripper is pressure compensating, so it delivers constant flow anywhere from 10 to 45 psi. A built-in check valve closes when line pressure falls to 1.75 psi. That keeps water in the line after each cycle instead of draining onto the lowest plants. The outlet is a nipple style rather than a barb, built to plug into Netafim multi-outlet manifolds. A flex tube adapter made for nipple outlet drippers lets a micro-tube lead run from it as well. Water goes straight to the pot, which keeps foliage and flowers dry and leaves sprays on the leaves undisturbed. The barbed inlet presses into a hole punched in the PE supply line.
Pairing the Dripper With a Multi-Outlet Manifold
On a flat 2-way manifold, this dripper splits its flow between two pots at about 0.50 GPH each. Flow at each arrow equals the dripper flow divided by the number of arrows on the assembly. Keep the same assembly type across a zone so every plant receives the same water and fertilizer. Because each dripper adjusts to pressure and elevation, uniformity reaches 94 percent even on sloped ground. Punch the supply line with a 3 mm plastic punch made for drippers and sprinklers. Press the dripper inlet fully into the hole, then seat the manifold or adapter onto the nipple outlet. Filter the water to 120 mesh to keep the dripper clear. A pressure regulator near 35 psi keeps the zone comfortably inside the working range. Twenty-five drippers cover repairs, small benches and trial plots without opening a large bag. Grey marks this flow at a glance, so replacements are easy to match in the field.
