Common questions.
Is backflow testing required by law in El Paso?
El Paso Water requires backflow prevention assemblies on qualifying commercial properties to be tested, typically annually, to protect the public water supply from contamination. Requirements vary by property and connection type — we confirm what applies to yours.
How often do I need to test?
Most commercial assemblies are tested annually. We track your specific due date and reach out before it’s overdue.
What happens if my device fails the test?
We quote the repair or replacement on the spot in most cases, so you’re not left non-compliant while you find a second vendor.
Do you file the report with El Paso Water for me?
Yes. Your certified test report is submitted directly to the utility as part of the service.
Do you test residential backflow devices too?
Our focus is commercial and multi-property portfolios — call to confirm if you have a specific residential situation.
Can you handle multiple properties on one schedule?
Yes — send us your property list and we’ll build one testing schedule and one invoice for the whole portfolio.
