How to fix a leaking sprinkler head

I describe a method to repair an irrigation sprinkler head that is continuously leaking. This video describes the basic anatomy of home sprinkler systems followed by a practical example.

The commonest cause of a continuous, low volume leak in a sprinkler head is a small debris particle that is holding the diaphragm of the control valve open. The particle is too large to be flushed beyond the valve, yet so small it may be drawn back up the line when water is not flowing. Therefore it is important to flush the line after disassembling the valve, to clear the proximal line of debris. If that effort fails you will need to replace the diaphragm or perhaps replace the solenoid. When the diaphragm is off, examine the seat for scratches and pits caused by debris binding against it.

THANK YOU! I’ve been looking for a tutorial that will show me the basics of valve repair/troubleshooting. I’ve got the same type of leak in my front yard as you have. I’m going to try this today!

@wmcraver You're welcome! Here in Canada there is snow on the ground now, so all sprinkler work will wait til spring.

@spelunkerd I wish I had a “snow break” from my sprinkler issues. :) I’m in AZ, and where I am, it rarely freezes or snows.
