How to Unclog a Sprinkler System

Dirt and debris can build up in all parts of a sprinkler system--pipes, risers and nozzles. If the water spewing from your sprinklers isn't as strong as it should be, it's time for a cleaning.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Garden Hose
• Wire Or Paper Clip

1. Turn off the system and remove all the nozzles and heads.

2. Turn on the water and let it run until a solid, clean stream flows from each head opening. Then turn the water off.

3. Dismantle each nozzle according to the directions in your owner's manual.

4. Hold the nozzle under a faucet or hose to blast out debris. Open small, clogged holes using a piece of wire or a paper clip.

5. Rinse out the filter basket or screen.

6. Reassemble and replace the heads and nozzles. Then turn on the water. If the system still seems sluggish--and your indoor water pressure is normal--the problem could be a leak in the line (see How to Repair a Leaking Irrigation System).

Tips & Warnings

• To dismantle some nozzles, you'll need a screwdriver or a special key that came with your system; other types you can take apart by hand.
