YCUA is currently compliant with state- mandated cross-connection control regulations.
This regulatory program has previously focused on on-site visual inspections of non-residential water service connections to identify potentially harmful interconnections to the Ypsilanti public water supply.
The program now also includes residential inspections in compliance with Michigan Department of Environment, Great Lakes and Energy (EGLE) regulations. YCUA conducts these inspections.
The Michigan Department of Environment, Great Lakes and Energy (EGLE) now requires public water systems to implement a cross-connection control program addressing residential service connections.
This web page serves to assist Ypsilanti water customers with their participation in this important safety program. YCUA has selected HydroCorp to assist with coordination, commercial site visits, and data and compliance management.

The anti-siphon fill valve device is located in the tank of your toilet. This device has a dual purpose: To fill the toilet and prevent backflow. This device must be placed at the proper height in order to insure that water from your toilet does not backflow into your drinking water. Proper placement is typically done during the installation process but can be easily overlooked. This device must be raised or the overflow pipe must be cut down in order to achieve a 1” air gap separation between the “critical level” of the assembly.

 Example: Hose connection vacuum breakers |  Example: Integrated vacuum breaker on outside hose spigot. |
 Example: Hose end in bucket |  Example: Hose end in pool |
 |
Vacuum breaker should not be subject to continuous pressure like the example here illustrates. (This type of irrigation set up/system would need to be corrected.) |
These require periodic performance testing by a Certified Tester.
