What Backflow preventer is right for my building/facility?

There are two types of Backflow prevention assembly devices:

  1. External - to protect the City's water system from cross-connection occurring on the customer's property
  2. Internal - to protect the customer from cross-connections occurring within the system/pipes on their own system

The City of Modesto's Cross-Connection Specialist is available to help conduct a backflow survey within your facility to determine what type of backflow prevention assembly is best to protect your facility and your personnel. You will receive a survey report complete with recommendations. To arrange for this free service you may contact us at 209-342-2246 or via e-mail at WaterBackflow@modestogov.com
