Replace rotary sprinkler head

[smanilov]

I need to replace Rainbird rotary sprinkler heads (R50). The sprinkler guy said I can do it myself - just unscrew the old one and screw in the new one.

Do I need to dig around it to the pipe to do it? If not, how can I make sure when I remove the old one that dirt does not fall into the hole?

Please, help me with any tips on how to do this.

Thanks!

Hi, Inside the head there is a filter which can be removed y itself. Like the guy said unscre the old when ground is pretty dry and install new one. Clean the filter in case dirt got sucked in.
