1) NRS, OS&Y and/or any Gate Valves utilized as shut off valves on Backflow Direct products are covered by original manufacturer’s warranty ONLY.
2) Reduced Pressure Principle Backflow Preventers (RP or RPDA) can and WILL discharge water. NEVER install an RP or RPDA in a location where any amount of discharge from the Relief Valve will cause property damage. For an indoor, pit, vault, mechanical room or enclosure installation of an RP or RPDA an auxiliary drain (SEPARATE AND INDEPENDENT of the Air Gap Assembly) is REQUIRED and MUST be properly sized for the Maximum Relief Valve Discharge Rate corresponding to the system/supply pressure. Backflow Direct shall not be responsible for any special, consequential or incidental damages, including without limitation, repair costs, lost profits, property damage, or any other costs resulting from labor charges, delays, vandalism, negligence, fouling caused by foreign material, adverse water conditions or any other circumstances, caused by lack of auxiliary drain, location of auxiliary drain or undersized auxiliary drain.
3) Air Gap Assembly will capture and evacuate light water discharge from the Relieve Valve caused by daily fluctuation in system/supply pressure. An Air Gap Assembly will NOT capture and evacuate the Maximum Relief Valve Discharge Rate caused by catastrophic valve or system failure. An auxiliary drain (separate and independent of the Air Gap Assembly) is REQUIRED and MUST be properly sized for the Maximum Relief Valve Discharge Rate. Backflow Direct shall not be responsible for any special, consequential or incidental damages, including without limitation, repair costs, lost profits, property damage, or any other costs resulting from labor charges, delays, vandalism, negligence, fouling caused by foreign material, adverse water conditions or any other circumstances, caused by lack of auxiliary drain, location of auxiliary drain or undersized auxiliary drain.
This warranty shall be invalidated by any abuse, misuse, misapplication, improper installation or improper maintenance or alteration of the products.
