Welcome to 1A Backflow & Services

To help keep our public water clean it must be isolated from undesirable reversal of water flow or mixtures of water with liquids, gases or toxic health hazard substances into the distribution of the potable water system. Backflow Prevention assemblies provide that protection and must be tested a least annually.

Billy Dominguez, Owner
Testing and inspection of backflow preventers is our specialty. We have become one of the most recognized and respected backflow assembly testing companies in our profession today. We have achieved this status through our high standards of service and have established a very strong reputable profile in our industry today since established in 1997.
