Emitters

What are emitters?

Emitters are irrigation devices used to provide a regulated amount of water to a specific plant or location.

Can I bury emitters?

(Kindly support us by leaving a comment below)

It is recommended to place emitters above ground or covered with light mulch with the outlet pointed towards the air. Emitters with the outlet in the dirt may clog with muddy water being drawn back into it upon shut down.

What could be causing my emitters to clog?

Dirt, such as sediment, sand, algae, or any number of things can get in your water and plug your emitters. It is always recommended to place a filter on your drip system. If your water is extremely dirty, water pressure can force contamination through the filter screen, so it’s important to give the filter element a timely, regular cleaning.

What does pressure compensating mean?

A pressure compensating emitter has a flow regulator built into it. These emitters deliver the same amount of water regardless of changes in pressure or terrain.

What can I do about emitters that gradually clog?

Calcium or hard water and very fine sediments that cake can eventually clog emitters, even if they are otherwise properly filtered. The simplest repair is to leave the old emitter in place and install another emitter near it.

How do I replace or repair leaky emitters, or I just don’t want to water at that spot any more?

Identify where the water is coming from. It can come from the punched hole or a broken emitter. If the hole is too big or if the emitter is leaking from places it shouldn’t, carefully remove it from the tubing and plug the hole with a goof plug.

Can I replace or repair an emitter?

Yes, it is common to replace a leaky or clogged emitter. Normally emitters are not repaired. Some are cleanable.

What pressure do emitters need to work?

Different types of emitters have varying pressure needs. It is best to check manufacturers’ specifications. Normally, basic emitters work best at 20 PSI or less and pressure compensating emitters work best at 10 PSI or more.

How many emitters can be put on one line?

That depends on the capacity of your line and what the flow rate of each emitter is. 1/2″ tubing can carry up to 240 GPH . If you choose to use 2 GPH emitters, divide 240 gph by 2 gph (240/2). The result, 120, is the most number of emitters you can put on a 1/2″ supply line.

Why do my emitters keep clogging?

Any foreign particles in your water — dirt, mineral sediments, algae — can plug your emitters. As always, we recommend a filter on your drip system. If your water is extremely dirty, high water pressure can force these particles through the filters screen.

Can I use emitters with pressure less than 10 PSI?

Most emitters work best at 20 PSI or higher. Non-pressure compensating emitters will work at pressures below 10 PSI, though flow rates will be correspondingly lower. Pressure compensating emitters may work below 10 PSI, but their flow rates may be erratic and can vary between emitters.Basic Drip Emitters and Pressure Compensating Emitters

What is the difference between non-pressure compensating and pressure compensating (PC) emitters?

Non-pressure compensating emitters tend to be lower in cost and work at pressures below 10 PSI. However, they are pressure dependent, releasing less water at lower pressures and more at higher pressures. Pressure compensating emitters (PC) maintain a consistent flow rate despite changes in terrain or pressure changes.

What does pressure compensating mean?

A pressure compensating emitter has a built-in flow regulating diaphragm that delivers the same amount of water regardless of changes in pressure or terrain.

Over time my emitters gradually clog. What can I do about this?

Calcium or hard water and very fine sediments that cake can eventually clog emitters, even if they are properly filtered. The simplest repair is to leave the old emitter in place and install another emitter near it. Of course, always use a filter when drip irrigating.
