CPVC can be used on both hot and cold lines, while PVC is for cold water only. PVC is frequently used as a drainpipe.

Noveon, Inc., the world leader in CPVC technology, invented CPVC more than 40 years ago. Astral CPVC is a patented rigid thermoplastic chlorinated polyvinyl compound used in the manufacturing of a plumbing system that won't pit, scale or corrode.

Yes, but you should watch the cost of fittings and plastic must be supported every two feet. Do not substitute fittings with Radiantec tubing. If you are using an open system, be sure that the materials are rated potable. All Radiantec polyethylene tubing is highly resistant to nearly everything. The reactivity charts show only a slight reaction to fuming nitric acid (above 1700° F)

Copper tube size (CTS) CPVC is designed for use in hot-and-cold-water distribution systems. CPVC systems are ideal for all potable water piping requirements in typical residential (single and multi-family), motel/hotel, mobile home, manufactured housing, light commercial, and institutional structures. CPVC systems conforming to ASTM D2846 are rated for continuous service at 100 psi and 180 degrees F and are marked accordingly.

Yes. CPVC can be installed at least 25% more quickly than copper or iron systems. Financial savings are also realized with regard to lower tool costs and insurance advantages. Considering the frequent rise and fall of the copper price structure, CPVC offers a continuing material cost advantage, often as much as a full 30% savings.

A CTS CPVC system will use the same size pipe that a copper system would, providing a full bore flow system. In general an IPS CPVC system will use the same size pipe as an iron system. CPVC piping will expand about 4 inches per 100 feet with a 100 degree F temperature change. The fact that CPVC has higher thermal expansion than metals has led to some concern.

When using CPVC with joints under slab, YOU MUST PRESSURE TEST THE SYSTEM BEFORE POURING THE SLAB. Also, it is wise to use 1" foam insulation pipe sleeve at changes in direction, where the pipe comes out of the slab, and at construction joints. The pipe should be evenly supported in smooth bottom trenches. The backfill should be free of rocks and debris. Provide some protection from abuse during the construction phase for the pipe where it emerges from the slab.

Quality of components, construction and optics. While all models are based on the same technology, each type of microscope employs different construction, size, optical quality, magnification power and method of use. Since the end test results should be basically identical with all models, selection becomes a matter of preference. Additionally, overall quality of components generally tend to correlate with ease of use and successful results.

CPVC solvent cement can be used on CPVC and PVC pipe. PVC solvent cement can only be used on PVC pipe. PVC stands for poly vinyl chloride. CPVC stand for Chlorinated poly vinyl chloride. CPVC is harder, stronger pipe. It requires a stronger solvent cement than PVC pipe. CPVC solvent cement is strong enough to bond CPVC pipe and fittings, so it is strong enough to bond PVC pipe and fittings as well.

CPVC piping systems have been installed and operated since 1959, and initial installations are still performing faultlessly. CPVC piping will not fail prematurely due to corrosion, electrolysis, or scale build-up in areas where water, soil, and/or atmospheric conditions are aggressive.

If the frozen section of pipe is accessible, wrap it with a cloth saturated with hot water. Keep the cloth hot by re-dipping in hot water as necessary. Be careful not to burn your hands. A second technique that is quite successful is to blow heated air directly on the area where the freeze occurred using a low wattage heater/blower such as a hair dryer. Obviously, prevention is the best way to address frozen pipe problems.

In areas where there is a likelihood that stresses or impact abuse will occur, a metal nipple is recommended. Such applications as tub fillers, showerheads, and outside sillcocks are examples. However, CPVC stub-outs for closets, lavatories, and sinks are appropriate.

CPVC can easily withstand the ultraviolet exposure commonly experienced during the construction phase of a project, provided on-site inventories are turned regularly as would be anticipated. If CPVC is used in above-ground, outdoor applications, protection from ultraviolet attack can be achieved by shielding or by painting the system with an exterior-grade latex paint.

A benefit of CPVC pipe is that numerous, inexpensive choices of cutting tools are available to the installer. CPVC piping has for years been cut by fine-tooth saws. The preferred method is the circular tubing cutter, modified with a plastic cutting blade. This cutter assures a square, clean cut each time and is extermely efficient in terms of labor. alternative method is the ratchet cutter.

Significant reduction in injuries, particularly burns, can translate to reduced workmen's compensation costs.

Yes. Due to the CPVC polymeric structure, costly condensation concerns are eliminated, further reducing the long-term problems that one expects with a metal installation. Also, CPVC offers a potable water distribution system that eliminates the metallic taste and potential health hazards associated with metal systems.

CPVC plumbing systems meet all model code approvals, including BOCA National Plumbing Code, Standard Plumbing Code, Uniform Plumbing Code, CABO 1- and 2- Family Dwelling Code, Canadian Plumbing Code, International Plumbing Code and International Residential Code, as well as California Plumbing Code. CPVC plumbing systems will not pit, scale or corrode in aggressive water and soil conditions, so water purity is maintained. In environments with aggressive water, pH levels of less than 6.

The thermoplastic properties of a Astral CPVC system provides a system that is four times quieter than copper plumbing systems, reducing the sound of running water and the potential of the pounding noise of water hammer. In addition, unlike copper piping materials, the thermoplastic properties of a Astral CPVC plumbing systems provide insulation to reduce condensation and "sweaty pipes." The material keeps hot water hotter and cold water colder than copper.

No, Astral CPVC plumbing systems have been used for more than 40 years and have not posed any health risks. Astral CPVC plumbing systems exceed ANSI/NSF Standard 61 for water quality with no pH level restrictions as found in copper pipe.

Astral CPVC has a flash ignition temperature of 900?F which is the lowest temperature at which sufficient combustion gas is evolved that can be ignited by a small external flame. Many other ordinary combustibles, such as wood, ignite at 500?F or less. Astral CPVC will not sustain burning. It must be forced to burn due to its very high Limiting Oxygen Index (LOI) of 60. LOI is the percentage of oxygen needed in an atmosphere to support combustion.
