A. Drip
emitters can get plugged from salt accumulation and debris. Never cut
irrigation lines that have drip emitters on it with a hacksaw blade. The
plastic debris created by the hacksaw blade is nearly impossible to keep out
of the irrigation lines. I will guarantee you that this debris will end up

in
your drip emitters and plug them. Cut PVC irrigation lines with a PVC cutter. It
leaves no debris to plugged emitters. You can cut polyethylene pipe, the kind
used for drip emitters, with a pruning shears.

Make
sure the ends of the drip lines can be cleaned by opening them up and letting
water flow for 15 or 20 seconds about once a month. You can buy little figure 8
devices to go on the end of the irrigation lines or you can bend them over and slip
on a small piece of PVC pipe to hold that shut.

Secondly,
put drip emitters facing up, not down. If salt accumulation is the problem and the
emitters can be removed without damaging the drip system, remove and soak them
in vinegar for a couple of hours.

If
you cannot open the drip emitters to clean them, try poking a needle or pin
through the opening to see if you can unplug them. In the past I have knelt
down on the ground and lifted the emitter to my mouth, after I washed the
outside, and sucked on the emitter to try to get debris cleaned from the
opening.

If
you cannot remove the emitters from the drip line, you might have to replace
them. Make sure when you buy drip emitters they are the kinds that you can open
and clean easily. Flag drip emitters are inexpensive and can be cleaned easily.
Button emitters can be more difficult.

Drip
tubing with built-in, in-line emitters can be the most difficult. If you buy
the built-in emitters, by a name brand such as Netafim, Toro, etc. make sure
you have a filter on your drip system somewhere after the valve.

If
you work on drip systems and have to cut the tubing, after you repair it, flush
the system with water by opening the ends and letting it run out the ends. If
you don’t do this, debris will get pushed into the emitters and can become a
problem.
