No water service connection to any premises shall be installed or maintained
by the Water Purveyor, unless the water supply is protected as required by
state regulations and this rule.
Service of water to any premises may be discontinued by the Water Purveyor,
if a backflow preventive device required by this rule and regulation is not
installed, tested, and maintained; if any defect is found in an installed
backflow preventive device; if it is found that a backflow preventive device
has been removed or bypassed if unprotected cross-connections exist on the
premises, and service will not be restored until such conditions or defects
are corrected.
