CETA PC Emitters

A quick guide to installing and maintaining your CETA emitters.

Step 1: Punch the Hole
Using a standard irrigation hole punch, create a hole directly into your 1/2" or 3/4" mainline tubing.

Step 2: Insert the Emitter
Locate the colored side of the CETA PC Emitter (this is the water inlet). Push the colored barb 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 barb to extend the water directly to the plant's root zone.

Step 4: Cleaning and Maintenance
If the emitter becomes clogged, gently twist and pull the top cap off to expose the internal diaphragm. Rinse the components with water to clear any sediment, then snap the cap back on.

Why should I use a pressure compensating (PC) CETA Emitter instead of a standard dripper?
The pressure compensating feature ensures the CETA PC Emitter delivers the exact same amount of water whether it is at the beginning or the end of a long tubing run, even on sloped terrain.

Standard (non-PC) emitters will output more water at the beginning of a line and less at the end as friction causes pressure to drop. PC emitters guarantee uniform watering.

Which direction do I install the CETA PC Emitter?
The CETA PC Emitter is one-directional. You must always push the colored barb into your mainline tubing or micro tubing, as the colored side serves as the water inlet.

The top outlet barb is designed to accommodate 1/4" micro tubing if you need to route water further away from the main delivery line.

What size tubing does the CETA PC Emitter connect to?
The CETA PC Emitter features 1/4-inch barbs on both the inlet and outlet. It pushes directly into 1/2-inch or 3/4-inch mainline tubing via a punched hole, or connects to 1/4-inch micro tubing.

We recommend using a dedicated pocket punch or key punch to create clean, consistently sized holes in your mainline to prevent leaks around the barb.

As I flush my system this spring, how do I clean the CETA PC Emitters?
To clean the CETA PC Emitter, simply twist off the cap to expose the diaphragm. Rinse away any debris or winter buildup, then snap the cap back on for a perfect seal.

Spring startup is the perfect time to check your emitters. Because these can be taken apart, you can easily restore full flow without having to buy and punch in replacement drippers.
