Commercial Precision With Built-in Anti-Drain Technology
The Netafim Woodpecker Jr. Emitter takes the legendary reliability of the standard Woodpecker and upgrades it with a built-in check valve for ultimate system control. Perfect for commercial greenhouses, nurseries, and large residential landscapes, these pressure-compensating (PC) drippers are designed to solve the common problem of low-point drainage. When the irrigation cycle ends, standard lines drain out at the lowest elevation, over-watering those plants while under-watering plants at higher elevations. The Woodpecker Jr. eliminates this entirely.
Every emitter in the system features a non-draining check valve (CNL) that requires exactly 7 PSI to open and snaps shut when pressure drops to 1.7 PSI. This ensures that the entire line stays full of water between cycles and that every single emitter starts and stops watering at the exact same moment. Punched directly into 1/2″ mainline tubing, this compact powerhouse delivers perfectly uniform pulses of water and nutrients, making it the premier choice for pulse-irrigation and precision commercial growing.
- Built-In Check Valve: Prevents low-point drainage by sealing shut at 1.7 PSI, ensuring the mainline stays full of water for instant startup on the next cycle.
- Simultaneous Operation: Because the line stays pressurized, every plant on the system receives water at the exact same time, eliminating dry spots.
- Continuous Self-Flushing: Features an extra-wide flow path that automatically clears debris during operation, drastically reducing the chance of clogging.
- Pressure Compensating: Maintains a uniform flow rate regardless of pressure fluctuations between 10.2 and 58 PSI.
- Compact Design: A smaller profile than the standard Woodpecker makes it ideal for tight spaces and intensive growing setups.

A quick guide to installing your Netafim Woodpecker Jr. emitters.
Step 1: Punch the Hole
Using a dedicated irrigation hole punch, create a clean hole directly into your 1/2″ or 3/4″ mainline tubing at the desired location.
Step 2: Insert the Emitter
Push the barbed inlet (the slightly narrower, pointed end) of the Woodpecker Jr. firmly into the punched hole until it snaps securely into place.
Step 3: Attach Micro Tubing (Optional)
If your plant is further away from the mainline, push a piece of 1/4″ micro tubing onto the top outlet nipple to direct the water precisely to the base of the plant.
