WARNING! Irrigation systems supplied by domestic or private potable water systems are considered to be a potential pollution hazard to the water supply. These systems must include protection to prevent possible backflow of irrigation water into the potable water supply.

Federal law requires a proper backflow device to be installed on any watering system to prevent contamination of the supply; whether it be pump or city water. Check your local water authority for installation requirements & codes. In many rural areas; specific requirements for landscape irrigation systems may not be covered in local plumbing codes and/or enforcement may be limited. HOWEVER...limitation in local authority does not alter the basic requirement for protection of the potable water supply.

Sprinkler Warehouse recommends purchasing a pair of our "GET-A-GRIP" Stainless Steel handles when selecting this Reduced Pressure Assembly.  This will prevent corrosion of the handles allowing them to last as long as the assemblies themselves.  A product option has been provided above for easier ordering.
 

All health hazard (toxic) and non-health hazard (nontoxic) connections including: irrigation systems; hospitals; morgues; medical/dental facilities; industrial/chemical plants and boiler feeds.

Reduced Pressure assemblies are approved for backflow prevention of toxic substances (liquid; solid; or gas).

1. Consult local codes for specific installation requirements and restrictions applicable to your area. It is recommended that system supply pressure be at least 20 psi
   
   
2. These instructions apply to models 860; and 860U; sizes ½" - 2" only. The valves may be installed only in the orientation/flow direction as shown.
   
   
3. The valve assembly must be installed where it is accessible for periodic testing and maintenance. Clearances shown in the installation views apply to exterior; interior and pit/vault installations and are only recommendations. These minimums do not apply to removable protective enclosures. Refer to local codes for actual requirements in your area.
   
   
4. PRIOR TO INSTALLING THE VALVE INTO THE LINE; FLUSH THE SUPPLY LINE OF ALL FOREIGN MATERIAL. Failure to flush the supply line may cause the check valves to become fouled and require disassembly and cleaning.
   
   
5. After installation SLOWLY fill the assembly with water and bleed air from the body using the # 3 and # 4 test cocks. Test the valve assembly to ensure correct operation. NOTE: All assemblies are tested at the factory for proper operation and leakage. If the valve does not pass the field test; it is most likely due to a fouled check valve. This is not covered by the factory warranty; and the valve cover must be removed and the check seats inspected and cleaned. Any damage or improper operation caused by pipeline debris or improper installation/start-up is not included in the factory warranty. In case of a possible warranty claim; contact your local supplier or FEBCO Representative. DO NOT REMOVE THE VALVE ASSEMBLY FROM THE PIPELINE.
   
   
6. The assembly must be protected from freezing and excessive pressure increases. Pressure increases can be caused by thermal expansion or water hammer. These excessive pressure situations must be eliminated to protect the valve and system from possible damage.
   
   
7. Plastic testcock plugs and tethers are provided (loose in box) for areas that require them.
