Backflow Tester List

State rules

Pennsylvania

Pennsylvania’s Department of Environmental Protection public-water-supply manual, Part VII, is the Department’s cross-connection control and backflow prevention guidance for suppliers. It says the manual gives the basic information a supplier needs to establish an effective program. It cites the construction rule that a public water supply may not be designed or constructed in a manner that creates a cross-connection, and it cites section 109.709(b): at the direction of the Department, the supplier shall develop and implement a comprehensive program to eliminate existing cross-connections or effectively contain sources of contamination, and to prevent future cross-connections. The manual does not create a state tester license.

The manual says cross-connections are prohibited unless controlled to the Department’s satisfaction, and it tells suppliers to install an approved backflow prevention device on service lines where the supplier judges a hazard exists, including categories of facilities the manual lists. It describes acceptable devices used for cross-connection control. Those passages put the program on the public water supplier once the Department directs it. They do not name a Pennsylvania tester examination, and they do not say ASSE, ABPA, or AWWA certification is a state license. A supplier’s ordinance can still name the tester credential that supplier will accept.

A property owner who receives a test notice is dealing with that supplier’s program, not with a statewide roster. The manual is the reference the supplier uses to build the program. Questions about whether a particular fire line, irrigation line, or industrial process needs a device belong to the supplier’s hazard judgment and to the Department’s direction under section 109.709(b). No fee and no roster appear in the manual passages used here.

EPA’s primacy page is the federal context: Pennsylvania runs its public-water-system program as a primacy state. EPA’s cross-connection manual is educational background. Neither document adds a Pennsylvania tester card. Hire the person your water supplier says may submit the test. Keep the supplier’s notice with the test. Part VII says the Department directs the supplier to act under the cited drinking-water section. That direction is what starts the local program.

What to do next

  1. Follow the notice from your water supplier; that is the program the manual describes.
  2. Ask which credential the supplier accepts, because the state manual does not name one.
  3. Do not look for a statewide tester roster in Part VII.
  4. Keep design questions about new connections with the supplier and DEP’s construction rule.
