What does it cost to test a backflow prevention assembly?

Backflow prevention assembly testing is done by private companies who set their own rates. Testing costs vary, so getting quotes from several companies is recommended.


Texas Commission on Environmental Quality, TCEQ, mandates the City of Killeen establish and maintain a cross connection control program. The City of Killeen Ordinance states the City will terminate water service should a property owner fail to comply with cross connection/backflow regulations. This includes testing and maintenance of backflow prevention assemblies.
