Sprinkler Head Maintenance
Where do I go to learn about how lawn sprinkler components work? There is a lot of literature on designing and laying out a system, but apparently nothing that explains, for instance, how a sprinkler head actually works.
So I have a rotary sprinkler head that sticks near the end of its travel and won't rotate. I clean the screen and nozzle, but this doesn't solve the problem. Where do I go from here---and why? That's the type of question I am currently faced with and would like to answer.
