Asset Preservation & Maintenance

Had Your Backflow Preventer Inspected Lately?

Do you have a sprinkler system? Make sure it has a backflow preventer and it is tested annually.

Backflow prevention devices protect public health and safety by keeping dangerous contaminants out of the public water system – and out of your own home.

Backflow inspections:

  • Are required annually by law in San Antonio and most municipalities.
  • Apply to all residences with in-ground sprinkler systems and many types of commercial businesses.
  • Must be done by a licensed tester that is selected, contracted and paid by the owner of the home or business.
