I had a problem with the sprinkler head I purchased a year ago, the spray pattern, controlled by a deflector was not working and the spray area kept expanding. I called AM Leonard and without ANY difficulty, they sent me a new unit. I was very impressed Love the sprinkler by the way
I use the Orbit Brass Impulse Sprinkler to water nursery stock in my holding area and newly planted stock in the nursery. Very reliable. I can turn it on with a timer and leave the nursery with confidence that the sprinkler head will not jam up.
