The Key Materials of Your Plumbing System
Chlorinated Poly Vinyl Chloride
Copper pipes have been used in home plumbing for many years, and copper piping is considered by many to be the best choice for home water conveyance. Another very common favorite of plumbers and home builders is polyvinylchloride (PVC) or chlorinated polyvinyl chloride (CPVC) piping. CPVC has replaced PVC in many areas because it is considered safer and less likely to present a chemical hazard to the water supply.
When deciding on whether to use copper pipes or CPVC, you must consider many factors. Both materials have advantages and disadvantages, and they vary in terms of cost and energy efficiency. The simple answer to the question of which one to use is that it depends on what you are using it for, how much you are willing to spend, and, of course, what your plumbing contractor recommends as the best for conveying the water in your area.
There are plenty of professional plumbers who prefer to use copper pipes because of its strength, resistance to corrosion and flexibility. Copper resists microbial growth and rust and can be recycled, making it an environmentally sound choice for home plumbing.
Copper pipe, however, is not suitable for use with water that has a low pH. Acidic water tends to corrode the piping and can, over an extended period of time, lead to copper contamination of the water.
When installing copper pipes, only soldering is required. If they are used to replace old pipes, their flexibility will reduce the need for fittings. Rust will not accumulate in these pipes, so friction within them is reduced. This reduces clogging problems when using copper pipes for drainage.
Copper retains heat well, and if installed under the normal frost level, it resists freezing. Experts say that even though copper pipes may cost more per length than some other materials, it pays for itself with its durability and energy savings.
CPVC pipes are essentially plastic pipes, and can be very easy to work with. CPVC pipes require the use of many fittings, but can be easily installed using PVC glue instead of solder. CPVC is very lightweight and easy to cut. It is strong and can be used in areas of the country where corrosion of metal pipes is common.
CPVC tubing has been investigated recently for possible chemical leaching, which is the transfer of chemicals from the plastic into the water. Studies have shown that CPVC is safe for home water systems and has been used by plumbers and builders for over 35 years.
One of the main disadvantages of CPVC is that it cannot be used outdoors because it degrades in ultraviolet light. It is, however, very suitable for indoor use and can be used for hot or cold water systems. It is resistant to household chemicals and burning and has a long service life.
When it comes to making a choice between copper pipes or CPVC for your home, always consult with your plumbing contractor. A reputable plumber will know the advantages and disadvantages of all types of piping and can make recommendations based on where you live and the quality of your water.
