Drippers, Micro-Jets & Foggers
PC or non-PC dripper?
A pressure-compensating (PC) dripper gives almost the same flow along a long row or on sloping ground, because its internal diaphragm offsets pressure changes. A non-PC dripper is simpler and cheaper and is enough for short lines on flat ground.
An adjustable dripper changes its flow when the cap is turned and suits landscaping with different plants side by side. All of these drippers are fitted on 16 or 20 mm lateral tubing with a punch.
Fitting drippers on the lateral
Make the hole for each dripper with a proper punch, not a nail or a drill; a ragged hole leaks and holds the dripper loosely. Push the dripper in straight and all the way so its barb seats fully inside the tube.
The spacing and the number of drippers per tree depend on the soil, the age of the tree and the water the crop needs. Before fitting the drippers, flush the tubes by opening the line ends so soil and chips do not get into them.
Preventing dripper clogging
The most common reason a dripper stops working is clogging: suspended particles, algae and mineral scale. A suitable filter at the head of the line, regular flushing of the lateral ends and frequent filter cleaning prevent most of it.
In hard water, lime scale slowly narrows the dripper passage; periodic acid flushing of the network, with an irrigation specialist's guidance, removes it. Pressure-compensating drippers should not be opened, because their inner diaphragm moves out of place.
Drippers, Micro-Jets & Foggers — Frequently Asked Questions
Which PC dripper flows are supplied?
2, 4, 8, 12, 16 and 24 L/h.
Which pipe are drippers fitted on?
16 or 20 mm lateral tubing.
Which dripper is better on slopes?
A pressure-compensating (PC) dripper.
Which land needs PC drippers?
Sloping land and long rows, where pressure changes along the line and a standard dripper would not give an even flow.
Why do drippers clog?
Because of suspended particles, algae or mineral scale in the water; a suitable filter and regular line flushing prevent it.
