Backflow Prevention Testing in Metairie & New Orleans

Earl’s Plumbing & Heating provides certified backflow prevention testing and repair for homes and businesses across Metairie, Kenner, and New Orleans. Annual testing keeps contaminated water from flowing back into the clean drinking supply and keeps you compliant with local water authority requirements.

Backflow happens when a drop in pressure lets used or contaminated water reverse direction into your potable lines. A backflow preventer stops that, but it has to be tested regularly to prove it still works. Our certified technicians test, document, and repair or replace assemblies, then handle the paperwork your water provider requires.

Who Needs Backflow Testing

  • Commercial properties, restaurants, and multi unit buildings
  • Homes with irrigation systems, pools, or fire suppression lines
  • Any property the water authority has flagged for annual certification

What Our Testing Includes

We inspect and test the backflow assembly, verify it holds pressure correctly, replace worn parts when needed, and submit the certified results. If a device fails, we can repair or replace it and retest the same visit whenever possible.

Frequently Asked Questions

How often is backflow testing required?

Most water authorities require certified backflow testing once a year. Some commercial and high hazard properties may need it more often. Earl’s tracks your schedule and can remind you when it is due.

What happens if my backflow device fails the test?

A failed device means it is no longer protecting your water supply and must be repaired or replaced. Our certified technicians can service or swap the assembly and retest it, often on the same visit, then file the passing results.

Do I really need a backflow preventer?

If you have irrigation, a pool, a fire line, or a commercial connection, yes, and it is usually required by code. It protects your family and neighbors from contaminated water reversing into the drinking supply.
