HOT AND COLD WATER PLUMBING SYSTEMS Designed especially for contractors PRODUCT INSTALLATION GUIDE Bow FlowGuard Gold® JANUARY 2013
P RODUC T INSTA LLAT ION GUID E Important Notice Bow FlowGuard Gold® CPVC Systems are designed to be installed according to the local plumbing code. Please consult your local authorities for applicable code requirements. Joining Bow FlowGuard Gold CPVC Pipe and Fittings Please read theh entire guide before you proceed. This is a step-by-step technical guide only. There are many ways in which to proceed based on building design requirements that must be considered in order to make an efficient system.
PRODUC T IN STA LLAT ION GUID E NOTE: The following steps 3, 4 and 5 MUST BE COMPLETED IN LESS THAN 60 SECONDS. Application of Primer and Solvent Cement 3. The use of primer prepares the bonding area for the solvent cement. Apply primer sparingly on pipe and fitting socket, and do not allow it to puddle inside fittings. Please note that there are "One-Step" cements for CPVC, which eliminate the need for primer.
FlowGuard Gold® Set and Cure Times Solvent cement set and cures time are a function of pipe size, temperature, relative humidity and the type of cementing "system" being used. Drying time is shorter in drier environments with smaller size pipes and in higher temperatures. The use of primer in two-step cementing increases drying time. Refer to the following table as a guide for minimum cure times before pressure testing begins. MINIMUM CURE TIME STARTS AFTER THE LAST JOINT HAS BEEN MADE UP.
PRODUC T IN STA LLAT ION GUID E Handling and Storage Pressure Rating Exercise reasonable care in handling CPVC pipe and fittings. Although Bow FlowGuard Gold® CPVC is a tough, resistant material, it does not have the mechanical strength of metal. Cover CPVC with a non-transparent material when storing out-of-doors as prolonged exposure to sunlight is not advised. If CPVC pipe is to be installed out-of-doors, apply latex paint to it. Do not step on, drag or drop objects onto the pipe.
FlowGuard Gold® JANUARY 2013 Hydraulic Design Water Hammer Hydraulic calculations should be made using the Hazen-Williams C value of 150. The following table can be used for calculating pressure loss of pipe and fittings. Losses for fittings are based on equivalent lengths of pipe. It should be noted that CPVC will not corrode or scale, so hydraulic losses will remain constant over the life of the pipe.
PRODUC T IN STA LLAT ION GUID E Transitions from CPVC tO Other Materials Transition fittings are available for connecting to other materials, valves and appurtenances and must be used for all hot water line connections. For cold water connections, male CPVC threaded adapters may be used. They are not recommended for hot water use as wide temperature fluctuations can result in a drip leak. TFE (Teflon) thread tape should always be applied to the threads to improve the seal and ease installation.
FlowGuard Gold® JANUARY 2013 Other Design Criteria Thermal Expansion CPVC systems, like all piping materials, expand and contract with changes in temperature. The coefficient of linear expansion is: 0.0000340 inch/inch-°F. FlowGuard Gold® pipe will expand four (4) inches per 100 feet of length with a 100°F temperature change. Expansion does not vary with pipe size. Expansion is only of concern on hot water lines.
PRODUC T IN STA LLAT ION GUID E Sweating • “Sweating” of pipes is the formation of water droplets on the pipe's exterior surface, the result of condensation of water vapor from the surrounding air. Sweating requires a cold surface with warm, humid surrounding air. This cold surface can be found on any metal pipe carrying cold water. Typically, the problem is controlled by insulating the cold exterior pipe surface from the air.
FlowGuard Gold® Estimating Primer and Cement Requirements The following guidelines are provided to allow estimation of primer and cement quantities needed.
PRODUC T IN STA LLAT ION GUID E chemical Compatibility REVISION DATE: JANUARY 2013 CPVC piping systems have been chosen for more than 50 years. Ideally suited for use in new construction, re-piping and repair projects within domestic plumbing, and industrial and fire sprinkler piping, CPVC products are unsurpassed in their corrosion resistance and ease of installation.
FlowGuard Gold® JANUARY 2013 Unacceptable Products - do not Use with FlowGuard Gold CATEGORY mold cleaners Pipe Clamp Pipe Tape Thread Sealants COMPANY PRODUCT Anabec Systems Anabec Advanced Cleaning Solution Fiberlock Technologies ShockWave LSP Specialty Products Acousto Clamp, Acousto-Plumb System Incompatible information is based on testing of products manufactured prior to October 2007. For more information regarding this product please contact the manufacturer.
PRODUC T IN STA LLAT ION GUID E OTHER CHEMICAL COMPATIBILITY CONCERNS Acetone in Primers, Cleaners and Solvent Cements • Primers, cleaners, and solvent cements containing appreciable amounts of acetone may cause rapid environmental stress cracking of CPVC metal insert parts during installation at freezing temperatures. Contact your primer/cleaner/solvent cement manufacturer for more information or recommendation of alternatives.
FlowGuard Gold® installed in proximity to CPVC piping systems, care should be taken to protect the CPVC from burning with torches or contact with molten solder and solder flux, as well as incompatible thread sealants, leak detectors, lubricants, or other chemical products which may be used on metal piping. Paint • Water-based acrylic latex paint is the preferred and recommended paint to use on Lubrizol CPVC pipe and fittings. Oil or solvent-based paints may be chemically incompatible.
PRODUC T IN STA LLAT ION GUID E OTHER CHEMICAL COMPATIBILITY CONCERNS Incompatible plasticizers include, but are not limited to, phthalates, adipates, trimellitates, dibenzoates, etc. Compatibility should be confirmed before selecting rubber or flexible vinyl materials for direct contact with CPVC.
