Prior to the creation of any cross connection or installation of a double check valve assembly or reduced pressure backflow preventer, the owner or their agent must file for a Cross Connection Permit. Click here to obtain the permit application form.
The permit will be reviewed to make sure the proper device is selected to protect the cross connection and that the proposed installation meets the requirements of 310 CMR 22.22. Applicants should take care to make sure all requirements are met otherwise the permit can not be issued.
Once the permit is approved and all other required permits have been obtained the applicant can proceed with installation of the device(s). Once installed the devices must be inspected and tested.
