5-1.31 CROSS CONNECTION CONTROL
- The supplier of water shall protect the public water system by containing potential contamination within the premises of the user in the following manner:
- by requiring an approved air gap, reduced pressure zone device, double check value assembly or equivalent protective device consistent with the degree of hazard posed by any service connection;
- by requiring the user of such connections to submit plans for the installation of protective devices to the supplier of water and/or the State for approval; and
- by assuring that all protective devices be tested at least annually. Records of such tests shall be made available to and maintained by the supplier of water. Such tests shall be conducted by certified backflow prevention device testers pursuant to he following requirements:
- a "general tester" certification will be issued when the applicant presents proof of satisfactory completion of a training course for testers of backflow prevention devices which has been approved by the department.
- a "limited tester" certification will be issued when the applicant presents proof of employment by a manufacturer as its agent for the servicing, maintaining and testing of backflow prevention devices.
- the department has the authority to require any person applying for certification or renewal of certification as a certified tester of backflow prevention devices to take a written, oral or practical examination, if it deems such examinations to be reasonably necessary in determining the applicant’s qualifications. The results of such examinations may be the sole basis for approval or disapproval of an application for certification or renewal of certification.
- at least three months before the expiration date of a current certificate, both the general tester and a limited tester must submit proof that they are still engaged in the activity represented by their current certification.
- a certification will be suspended or revoked, on due notice and an opportunity for a hearing thereon, for any of the following reasons: submission of false test reports for backflow prevention devices; proof that the person is no longer engaged in servicing, maintaining and testing backflow prevention devices; or failure to apply for recertification.
- The supplier of water should not allow a user to establish a separate source of water. However, if the user justifies the need for a separate source of water, the supplier of water shall protect the public water system for a user who has a separate source of water and does not pose a hazard as detailed in subdivision (a) of this section in the following manner:
- by requiring the user to regularly examine the separate water source as to its quality;
- by approving the use of only those separate water sources which are properly developed, constructed, protected and found to meet the requirements of sections 5-1.51 and 5-1.52 of this Subpart; and
- by filing such approvals with the State annually.
- All users of a public water system shall prevent cross-connections between the potable water piping system and any other piping system within the premises.
- Any installation, service, maintenance, testing, repair or modification of a backflow prevention device shall be preformed in accordance with the provisions of any county, city, town or village having a plumbing code. For this section, a backflow prevention device is an approved air gap, reduced pressure zone device, double check valve assembly or equivalent protective device designed to prevent or contain potential contamination of a public water system. All individuals who perform testing of backflow prevention devices shall be certified, in accordance with subdivision 5-1.31 (a) (3) of this section.
