Why do heads sink or tilt in San Marcos yards?

Soil under San Marcos moves seasonally. Hill Country limestone and blackland clay — mixed infiltration, rocky trenches, and hard water. We reset heads on swing joints so the next soil cycle doesn't crack the lateral.

Does San Marcos water quality affect nozzles and emitters?

Yes. Mineral-heavy supply in this part of Hays County scales nozzle orifices and drip emitters, which shows as a shrinking spray radius. We clean or swap the affected parts and add filtration at the zone when it keeps recurring.

Who receives the backflow test report in San Marcos?

Your MUD or water district. We test the assembly, note any repairs, and file the certification with the correct Hays County authority so your account stays compliant.

Is annual backflow testing required in San Marcos?

Yes — irrigation backflow assemblies in San Marcos need a yearly test by a licensed tester. We handle the test, any rebuild parts, and the paperwork submission for you.
