Backflow Base / Tester certification / Pennsylvania

Backflow tester certification in Pennsylvania.

25 Pa. Code 109.709 makes the customer responsible for backflow protection and has DEP direct suppliers to run cross-connection control programs. It says nothing about tester qualifications, so each supplier sets them.
