Plumbing Pipes & Fittings For Potable Water

When shopping for plumbing pipes and fittings for potable water, what should you look for? What criteria should you use to judge products and manufacturers? We’ll share our recommendations for those searching for the best plumbing pipes and pipe fittings for potable water.

Quality

Quality can take many forms. First and foremost is dimensional stability. Do the pipes fit the vast majority of the time? Is the interior as smooth as it should be? If a manufacturer struggles to meet this basic criterion, you have to wonder about the chemical formulation they’re using. Merely stating that they have a high level of quality or quality management department is insufficient. Reviews are almost meaningless unless you’re talking to project managers who installed that brand of pipe in their walls five years ago and are still happy with it.
A rough proxy for quality is their warranty. Good PVC and CPVC pipe should last thirty years. If they only offer a warranty for a couple of years or limit the warranty to installation instead of product quality, don’t buy their pipes.

Third Party Certifications

When researching CPVC pipes & manufacturers in India, third party certifications are a good way to verify the quality of a product and the organization that produces it. ISO certification demonstrates that they have processes in place to ensure high levels of quality, whether it is smooth pipe that doesn’t break at unexpectedly low pressures or meeting chemical reactivity requirements. A better standard is the one for equipment in contact with food and water like those set by the NSF. Only one pipe manufacturer in India has achieved the stringent NSF standards for potable water pipes.

Suitability for the Application

Don’t blame the product if you choose the wrong one for the application. For example, PVC pipe isn’t poor quality if it fails at 200 degrees Fahrenheit. The real solution is to install CPVC pipe that can handle sustained exposure to near boiling temperatures. Another factor to consider is what the pipe will be exposed to. All pipes can handle exposure to drinking water, but some pipes and the adhesives used to glue them together will degrade on exposure to hand lotions washed down the drain or other chemicals. Furthermore, the pipe needs to be rated for the pressures it will be subjected to. Don’t buy pipe with a 200 PSI rating and complain if it fails at 300 PSI.

Overall Price

Don’t buy pipe based on the per item price. For example, the price will include taxes, import duties if you buy imported pipes, and transportation costs. Take all of the costs into account and buy the pipe that is the best overall value. This includes hangers, insulation and other hardware you may need to install the pipe. Pipes that cost a little more but act as de facto insulation are worthwhile in this regard. Conversely, you should be careful of buying cheap pipe when it comes with a requirement to use their overpriced labor.
Avoid pipes that require further reinforcement, since that adds to the complexity and overall installation costs. Anywhere there is a mistake, you end up with a potential failure point

The Benefits of Using CPVC Piping Systems

    There are a number of benefits to using CPVC piping systems. This explains why CPVC pipe has become one of the most common forms of piping used today. Let’s address some of the benefits of using CPVC piping. The Low Price The initial CPVC pipe price is lower than the purchase price for metal pipe. However, the cost savings ripple through the supply chain. CPVC pipe is lighter than metal or ceramic pipe, so you pay less to ship it to the installation site. It is easier to cut, assemble and install, so installation costs are lower. In fact, installation can be done with fast cold welding. You can use low skill assemblers, since they don’t have to have dangerous welding equipment. And they won’t need to be slowed down by safety measures because they’re using a heat source. That reduces labor costs. You also enjoy lower maintenance costs over the years, because CPVC pipe, good cutters, chamfering tools and CPVC solvent give you leak proof joints. They’re complet...

What factors determine the CPVC pipe price you may be quoted? What determines the price you’ll pay for CPVC pipes?

What factors determine the CPVC pipe price you may be quoted? What determines the price you’ll pay for CPVC pipes? Pipe Length One factor that determines the price you’ll pay for CPVC pipe is the amount of plastic that goes into it, while the difficulty of forming it is another factor. For example, ten foot and three meter lengths are easy to find, while 20 foot and 10 meter lengths are more difficult to make. Shorter lengths are easier to make and sell in higher volume, reducing their cost per unit of length. Pipe Diameter and Thickness The thicker the pipe, the more expensive it is simply due to the amount of material in it. The wider the pipe diameter, the more the pipe costs. Very wide pipes are more difficult to make and sell is lower volumes, both of which raise their price tag. A related issue is the type of ends on the pipes. Pipes that have simple flat endings are cheaper to make than those with male or female screws on the end. Whether it costs more becaus...

How much does CPVC Pipe Price Cost?

How much does CPVC pipe cost? CPVC pipe price varies based on several factors. We’ll address them here. Material CPVC pipe prices are always lower than metal, because plastic is both a cheaper raw material and cheaper to shape into the final desired form. For example, CPVC schedule 80 pipe costs about 60 percent of the price of schedule 40 carbon steel pipe. And it is a third of the cost of propylene lined steel schedule 40 pipe. CPVC pipe costs a little more than PVC pipe, but you get piping that has greater fire resistance and better impact strength. CPVC pipe costs about twenty percent more than similarly sized PVC pipe. However, there are other factors that go into the final price you pay for CPVC pipe. Size The wider the pipe, the greater the cost. For example, 3 inch diameter extruded pipe costs roughly twice as much as 2 inch diameter pipe. This is partially due to the fact that the wider pipe has more plastic in it. For this reason, when one pipe has a thicker...
