The Multi-Outlet Dripper Assembly (DMWST) is a Netafim 4-Way Stackable Assembly designed for nurseries, greenhouses, and home growers who need to water many potted plants from a single emitter. It attaches directly onto the outlet barb of a Woodpecker or Woodpecker Jr. Emitter (emitter sold separately), and when paired with a 4-Way Flat Assembly (DMWASS), it divides one emitter's flow evenly across eight separate containers.
Each assembly includes two 18" and two 30" arrow-dripper tubes for flexible placement around pots of different sizes. Remove the Stackable Assembly to drop back to 4-way watering, or seal off the emitter entirely with a shutoff cap when not in use. Note: dividing flow across 8 outlets significantly reduces GPH per container, so higher-flow emitters are recommended.

Step 1: Install the Emitter
Punch a Woodpecker or Woodpecker Jr. Emitter into your mainline tubing at each container location.
Step 2: Attach the Stackable Assembly
Push the DMWST 4-Way Stackable Assembly onto the emitter's outlet barb.
Step 3: Add the Flat Assembly
Push a 4-Way Flat Assembly (DMWASS) onto the outlet of the Stackable Assembly to bring the total to 8 outlets.
Step 4: Distribute the Tubes
Route the 18" and 30" arrow-dripper tubes to each container and stake the drippers into the soil.
Can I use the DMWST assembly by itself?
The DMWST is designed to be stacked with a 4-Way Flat Assembly (DMWASS) to reach 8 outlets.
Without the DMWASS, the Stackable Assembly alone does not create a functional 4-way split — order both for a complete 8-container setup.
What happens to the flow rate when I water 8 containers from one emitter?
The flow divides evenly across all 8 outlets, so a 1 GPH emitter delivers about 1/8 GPH to each container.
Choosing a higher-flow emitter helps ensure each container still receives adequate water.
How do I stop watering a container temporarily?
Remove the Multi-Outlet Dripper Assemblies and seal the emitter outlet with a Woodpecker shutoff cap.
This lets you take a plant off the watering schedule without removing the emitter itself.
