Removing or Disconnecting a Backflow Device
Before removing or disconnecting a backflow device, you must receive prior approval from our Cross-Connection Program supervisor, in compliance with City Code: 7-03-001-0015 F.11 and J.5.
If you feel there is a need for removal or disconnection of your backflow prevention device, please email pretreatment@flagstaffaz.gov with your name and address or call 928-213-2475. Once approved, there are two options to ensure removal meets the requirements of this section of the City Code to protect the City's water supply:
Option A
Call (928) 213-2475 to schedule an appointment with a City pretreatment inspector to verify the work is performed properly and confirm there is no danger to the water system.
Option B
Email Pretreatment photo documentation of the following:
1. Picture of the device with serial number
2. Location of the device on the property
3. The removal of the device/ capped pipes
4. Location after the removal
If you find a device has been removed without approval, please notify us. We must be able to access the piping to ensure that it has been capped properly.
If a residential fire line is being abandoned, the piping must be disconnected to avoid threats to the City's water system.
