Backflow Base / Tester certification / Louisiana
Backflow tester certification in Louisiana.
LAC 51:XII.346 lets a backflow assembly be tested by a Plumbing Board licensed plumber with a Water Supply Protection Specialist (WSPS) endorsement, or by a tester meeting ASSE 5110 or holding a certificate from a national organization approved by the state health officer. Each water system sets its own reporting rules.

The state sets a minimum; a water system may ask for more.
What it takes
- Credential
- SPBLA plumbing license with Water Supply Protection Specialist (WSPS) endorsement, or an ASSE 5110 / nationally recognized tester certificate approved by the state health officer
- Before you start
- WSPS endorsement attaches to a master or journeyman plumber license issued by the Plumbing Board. Landscape irrigation contractors licensed by the Horticulture Commission can test irrigation assemblies with an SPBLA special endorsement.
- Training
- Board-certified training program following ASSE Series 5000 or another board-approved national program. A licensed plumber who completes one qualifies for the exam.
- Exam
- Board exam for the endorsement, or verified results of an exam given by a board-certified organization. A training provider says since Jan 1, 2025 a national exam (ABPA or ASSE) must be passed before applying; not confirmed from a board source.
- Renewal
- A training provider page says proof of a board-approved recertification program is needed every three years in addition to yearly endorsement renewal. Not confirmed from a board source.
Certificates from elsewhere
- ASSE 5110: accepted as it is. LAC 51:XII.346 allows testing by a tester who meets ASSE 5110-2009 as an alternative to the plumber WSPS route. A water system may still add its own requirements.
- other: accepted as it is. Certificate from a nationally recognized backflow certification organization approved by the state health officer. The rule does not name which organizations.
No other state's certificate is named as valid here. Ask the program before you rely on one.
