Product Overview
Are you struggling with uneven crop growth caused by low-line pressure and unequal water distribution in your greenhouse or nursery? The commercial-grade Netafim™ Woodpecker Pressure Compensating (WPC) Jr. Drippers are the ultimate solution for precise, uniform micro-irrigation. Engineered for commercial bench-top containers and overhead hanging basket irrigation assemblies, these industry-leading button drippers ensure that every single plant receives the exact same volume of water and liquid nutrients, regardless of its position along the lateral line.
The standout feature of the Netafim Woodpecker Jr. emitter is its integrated high-performance check valve. This mechanism prevents the dripper from discharging a single drop of water until the entire lateral line reaches a threshold of 5 PSI. By forcing the system to pressurize completely before irrigation begins, it solves the widespread problem where plants nearest to the water source get flooded while those at the end of the line suffer from under-watering. Operating smoothly across a vast 2 to 50 PSI pressure range, it delivers unyielding flow consistency across varying terrains.
Key Features
- Advanced Pressure Compensation (PC): Maintains a perfectly constant, uniform flow rate across varying incoming pressures ranging from 2 to 50 PSI.
- Built-In Check Valve (CNL Feature): Prevents line drainage when the system shuts off, keeping lines fully charged with water to facilitate immediate, simultaneous watering during the next cycle.
- 5 PSI Anti-Drip Activation: Emitters remain sealed until the line pressure hits 5 PSI, ensuring the entire system pressurizes fully to eliminate uneven front-to-back watering splits.
- Nursery Assembly Ready: Optimized for easy pairing with plastic weights, micro-tubing, and specialized drip stake assemblies for container benching or hanging floral baskets.
- Patented Woodpecker Self-Flushing: Unique internal continuous self-flushing mechanism clears organic debris during operation, preventing clogging and reducing maintenance overhead.

Frequently Asked Questions (FAQ)
Q1: Why do these Netafim Woodpecker Jr. drippers require 5 PSI to open?
A: The 5 PSI opening threshold is an intentional, pro-grade feature designed to resolve unequal pressure distribution. In large zone layouts, water naturally trickles out of the closest drippers first, flooding nearby crops while far-end plants stay dry. Forcing the entire line to build up to 5 PSI guarantees that all drippers across your entire greenhouse map pop open and begin watering at the exact same fraction of a second.
Q2: What is the purpose of the built-in check valve?
A: When your irrigation timer cuts power, the internal check valve closes instantly. This keeps the supply lines fully filled and charged with water between cycles instead of letting the lines drain out onto the floor. This eliminates the lag time required to refill the lines during your next watering schedule, conserving water and ensuring high accuracy for short-burst pulse watering.
Q3: How do these button drippers handle hard water scaling and soil clogging?
A: Netafim WPC Jr. button emitters feature a patented internal continuous self-flushing design. While irrigation cycles run, a flexible, premium silicone diaphragm actively shifts to flush out micro-sediments, mineral deposits, and particulate nutrients before they can calcify or form a clog, minimizing lines maintenance significantly.
Q4: Can I push these drip emitters directly into standard polyethylene supply tubing?
A: Yes. These button emitters are built with a sharp, barbed inlet tail piece. Using a standard irrigation punch tool, you can pierce holes directly into your main 1/2″ or 3/4″ solid PE poly supply tubing lines and snap the barb tightly inside for a secure, leak-free commercial friction fit.
