That said.....#1 maintenance item is usually making sure your heads are all spraying properly. Not clogged.....and pattern is correct...including distance and degree of circle.

Next in priority is to make sure your timer is programmed correctly.

Both the above items can be checked fairly easily.

In case you get busy and forget or something happens in between PM.......the symptoms of any issue will show itself via damaged or dying landscape area(s) or excess water laying on property or surrounding hardscape(s) (sidewalk, driveway, patio, street, etc.) or screeching noises coming from your pump...
