Brown Spots in Your Lawn
If patches of your lawn are turning brown while neighboring areas stay green, your sprinkler system isn't delivering water evenly. The fix is usually quick — once you know which head is the problem.
Likely causes
What's usually causing this
Broken or cracked sprinkler head
A head that's been hit by a mower, edger, or vehicle splits along the riser. Water pools at the base instead of spraying. The brown patch sits directly downstream of where coverage should be.
Clogged nozzle from sediment
Texas water carries sediment, especially after main breaks. A partially clogged nozzle still pops up but sprays a weak, uneven pattern — leaving the far edge of its zone dry.
Sunken or tilted head
Heads can sink as soil compacts over years. A tilted head sprays at the wrong angle, missing the area it was installed to cover. Brown spots in a consistent pattern across the lawn often point to multiple settled heads.
Zone pressure problem
If multiple heads on one zone are weak, the issue may be upstream — a partially closed valve, a kinked line, or a pressure regulator that's failing. The whole zone underperforms even though no single head looks broken.
