Backflow Testing in San Marcos, TX

830-203-0738
San Marcos requires annual backflow testing – here's what that means for you.
If your home has an irrigation or sprinkler system, the City of San Marcos requires it to be tested by a licensed backflow prevention assembly tester every year. The test verifies that your backflow preventer is working correctly – preventing irrigation water, fertilizers, and other contaminants from flowing backward into the city's drinking water supply.
Once the test is complete, a compliance report has to be filed with the city. We handle that for you. You don't have to figure out the form, the portal, or who to send it to.
Who needs backflow
testing in San Marcos?
Any homeowner in San Marcos with an in-ground irrigation or sprinkler system almost certainly has an annual testing requirement. If you've received a notice from the city or your HOA, that's your reminder. If you haven't received one yet but have an irrigation system, don't wait – testing requirements don't go away, they just become overdue.
Not sure if your property requires it? Call us. We'll tell you in about two minutes.
