Backflow Tester List

State rules

West Virginia

West Virginia’s legislative rule on cross-connection control and backflow prevention, filed with the Secretary of State, governs public water systems and is read with the state public-health code sections it cites. The rule says no person shall install or maintain an unprotected cross-connection in a public water system. The Commissioner or a designee may determine, after a risk assessment, that a water supply system must have a backflow prevention assembly. The rule lists triggers that include a cross-connection with a sprinkler or fire-suppression system, an auxiliary water source or well, and other listed hazards. If an auxiliary supply connection is not approved, the customer installs an approved air gap or an approved interchangeable connection with a reduced-pressure backflow prevention assembly. The public water system establishes a program approved by the Commissioner.

The West Virginia cross-connection rule requires public water systems to keep a program approved by the Commissioner.
Who may test an assembly
The rule requires approved protection and a water-system program. It does not, in the passages reviewed, issue a state tester license.

The rule defines a cross-connection as a physical link between two otherwise separate systems, one with potable water and the other with water, steam, gas, or a chemical of unknown or questionable safety, so flow may reverse with the pressure difference. An unprotected connection is barred. The public water system keeps a program the Commissioner approves. If an auxiliary-supply connection is not approved, the customer provides the air gap or reduced-pressure assembly the rule describes.

The rule text reviewed does not create a named state backflow-tester license and does not say the Commissioner accepts ASSE, ABPA, or AWWA cards as the tester credential. A water system’s approved program can still specify who tests. A customer should ask the public water system for the approved program and for the credential that program requires. Fire-suppression and auxiliary-well connections are specifically called out as situations that can require protection, so those facts should be disclosed when asking.

No fee or roster is stated in the rule passages used here. EPA’s cross-connection manual explains why programs exist. It is not a West Virginia tester license. The Secretary of State rule file is the text relied on for this record. Ask the water system which credential its Commissioner-approved program requires before you hire anyone. Disclose a well, an auxiliary supply, or a fire-suppression connection when you ask.

What to do next

  1. Ask the water system for the Commissioner-approved program before you hire a tester.
  2. Tell the system if you have a well, auxiliary supply, or fire-suppression cross-connection.
  3. Do not assume a national tester card is named in the state rule; the passages reviewed do not name one.
  4. If the connection is not approved, ask whether the rule’s air gap or reduced-pressure assembly applies.
