(D) All double-check valve assemblies must be installed in drainable pits wherever below-ground installation is necessary, in accordance with detailed specifications provided by the town. Double-check valve assemblies may be installed in a vertical position with prior approval from the town, provided the flow of water is in an upward position.
(E) Reduced pressure principle backflow prevention assemblies must be installed in a horizontal position (unless specifically designed for vertical installation) and in a location in which no portion of the assembly can become submerged in any substance under any circumstance. Pit and/or below grade installations are prohibited.
(F) The installation of any backflow prevention assembly which is not approved by the town must be replaced by one which is approved.
(G) The consumer shall make sure all backflow prevention assemblies are working properly upon installation and must furnish the following information to the town within 15 days after a reduced pressure principle backflow preventer (RP), double-check valve assembly (DCVA), pressure vacuum breaker (PVB), double-check detector assembly (DCDA), or reduced pressure principle detector assembly (RPDA) is installed:

(H) When it is not possible to interrupt water service, provisions shall be made for a "parallel installation" of backflow prevention assemblies. The town will not accept an unprotected bypass around a backflow preventer. Bypass lines will have at least the same degree of protection as the backflow preventer being bypassed.
