Why Is There A Restricter Washer In Lawn Sprinkler

Question From: Los Angeles, California, United States
Q: Why do they put a restrictor washer in an orbit oscillating lawn sprinkler?

A: You've got me on that one. The only reason I can think of is to increase the water pressure. The folks at Dramm make the best sprinklers available. You can contact the consumer department at [email protected]. Best And Happy Yardening, Nancy.
