Gilmour Pattern Master Impulse Sprinkler

Gilmour Pattern Master Impulse Sprinkler

The first time I used it, I turned it on and about 5 minutes later I looked out the window and all I saw was a geyser coming out. The sprinkler hed had unscrewed. (I did not check it before I used it). I put it back in and made sure it was tight and it has been working GREAT ever since. So far I really like it and the birds like it also.
