What Are Pressure Compensating Drip Emitters? 

Pressure compensating drip emitters, otherwise known as PC emitters or PC drippers, are devices designed to control water flow to ensure uniform discharge regardless of variations in water pressure. Among drip irrigation heads, PC emitters are often chosen as the solution when watering areas with significant differences in elevation or in landscaping or farming projects that require efficient and precise water distribution.

 

Drip Emitters FAQ: Pressure Compensating Drippers

What is the difference between pressure-compensated and non-pressure-compensated drip emitters?

When discussing drip emitters and determining the best one for your needs, it’s important to understand the similarities and differences between the two types. While both pressure-compensating drip emitters and non-pressure-compensating drip emitters will deliver uniform water flow, several key factors set PC drippers apart. Pressure-compensating drippers can handle a wider range of water pressures and also allow the use of more drippers in one line.

What is the difference between button drippers and pressure compensating drippers?

Button drip emitters – also known as button drippers – are similar to pressure compensating drippers in that they release water at a set flow rate. However, unlike PC drippers, button drippers do not factor in changes in water pressure, so they are best suited for use in smaller areas or systems with stable water pressure.

How to install pressure compensating drippers?

Pressure-compensating emitters are fairly easy to set up. Use a designated hole punch to create a hole in your drip line tubing. Then, insert the pointed end of the dripper into the hole, pushing it in firmly. You may need a small piece of small-diameter drip tubing to connect the dripper to the main line. Be sure to position the PC drippers evenly based on the water needs of your plants. Drippers should be installed toward the base of each plant.
