Prior to installation, all required permits shall be obtained from the building and water departments having jurisdiction. 2. Inspections are required: prior to corrosion protection (grease and sleeve) prior to pouring thrust blocks, FD will measure bearing area for hydrostatic testing, and for flushing. All inspections shall be scheduled at least 48 hours in advance. Inspections canceled after 1 p.m. on the day before the scheduled date will be subject to a re-inspection fee. To schedule an inspection call (760) 602-4660. 3. Installation, inspection, and testing shall conform to 1999 NFPA 13 and 1995 NFPA 24. Underground mains may be center-loaded prior to visual inspection, so long as all D.I. fitting joints are left fully exposed. 4. Fire hydrants shall be approved wet barrel style per Carlsbad Public Works standard. The 4" outlet shall face the fire department access road. All outlets shall be provided with National Standard Threads (NST). 5. Fire hydrant supply piping shall be a minimum of six inches in diameter. The lowest operating nut shall be a minimum of 18" above grade and the hydrant flange shall be a minimum of 2" above grade. 6. Fire hydrants shall be a minimum of 40 feet from all structures. A keyed gate valve shall be provided for each hydrant in an accessible location. Valves shall not be located in parking stalls or in areas subject to obstruction. 7. All pipes shall be approved for use in fire service systems (Class 150 minimum). Class 200 pipe shall be used where the pressure may exceed 150 PSI. 8. Riser spools shall be cement-lined-mortar-coated with welded flanges, no exceptions. These would occur at the Backf low prevention device assembly and at the end of line. 9. All bolted joints shall be cleaned and thoroughly coated with No-ox grease or other corrosion retarding material after assembly and prior to poly-tube (sleeve) installation. 10.

Full flange caskets shall be used, rubber gaskets are not permitted 14. Bury depth shall be a minimum of 36 inches in all areas, including finished grade. 15. Thrust blocks, or other approved method of thrust restraint, shall be provided at all changes of direction and elevation. Thrust block calculations shall be provided and in accordance with CMWD Standard DWG. W19. The trench shall be excavated for thrust blocks and inspected prior to pour. All corrosion protection shall be in pace. A hydrostatic test (200 psi for two hours or 50 psi over maximum static pressure, whichever is greater) shall be witnessed by a CFD Inspector. The trench shall be back-filled to prevent movement of the pipe. The system shall be thoroughly flushed before connection is made to overhead piping. Flow shall be through a minimum of a 4" hose or pipe unless otherwise approved by the CFD inspector. A CFD Inspector shall witness the flush. The following flush connections shall be made: <4 in underground main - two (2) 2.5" coupling & hose 4 in underground main - one (1) 4" coupling & hose 6 in underground main - one (1) 4" coupling & hose 8 in underground main - one (1) 4" coupling & hose Larger than 8 in - Contact the Fire Prevention Bureau NOTE: - The flushing operation shall be of sufficient time to ensure thorough cleaning, THOSE SYSTEMS GREATER THAN 4 INCHES IN DIAMETER SHALL REQUIRE THE USE OF A SINGLE LARGE DIAMETER HOSE. All flushing shall be coordinated with the appropriate Water Authority and in accordance with the appropriate "Storm Water Protection" requirements of 'Regional Water Quality Control Board - San Diego Region's requirements for potable water discharges - Order No. R9-2002-0020.
