Indian manufacturing ranges from poor quality items to world class products. This is why you can often find products as good as the best imports domestically. However, it takes some work to find them. What should you look for when researching CPVC pipe fitting suppliers in India?
Third Party Certifications
You can outsource the determination of a product’s quality by using third party certifications. The hard part is determining which certifications are worth it. For example, quality awards from industry associations are meaningless if it is a group of friendly business owners joined together to market their products and give trophies to each other. Similarly, top seller awards don’t necessarily translate into good product quality.
They may be selling a lot of pipe that isn’t going to last more than a few years because it is cheap.
The solution for vetting CPVC pipes & fittings manufacturers in India is to verify that organizations have achieved independent, reputable third party certifications. A good starting point is the ISO quality standard. Note that their engineers having attended ISO training classes or being members of engineering societies isn’t good enough. The business itself has to be ISO certified. A better standard for potable water pipes is the one by NSF. NSF International is a world-renowned organization known for its stringent quality requirements for anything that touches food, beverages and drinking water. Only one manufacturer in India, Ajay Pipes, has met their high standards. This means you know their products are the safest ones available for water pipes.
Verify their certifications. Look at the paperwork. After all, anyone could stick an ISO graphic on their website. If they can’t produce this paperwork and explain their testing techniques, you can report the issue to the organization that either certified them or that they said issued that certification. Then you’ll know for certain if the pipe manufacturer is legitimately certified.
Warranties are a proxy for the quality of the product. For example, manufacturers who know they make poor quality pipe won’t offer a good warranty. PVC and CPVC pipe can last forty years in the field assuming it is used in suitable applications. For example, it isn’t the manufacturer’s fault if PVC pipe fails because you connected it to the hot water heater.
A warranty that’s only good for a few years is a major red flag. A warranty that only covers installation defects is another warning sign. Be very careful of manufacturers that only offer a warranty if you use their installers or buy many other products from them. They may add so many terms and conditions that the warranty is almost unserviceable by design.
Select pipe manufacturers who offer the best overall value in piping. This is not necessarily the cheapest product. After all, you don’t want to buy all new replacement pipe in five years after fixing the associated water damage. Pipe that has poor dimensional stability will often fail to fit into the fittings, causing you to have to discard it. That’s a waste of time and money. You can get a rough estimate for their overall quality in this case by assembling the pipes to fittings yourself. If a fair number don’t fit, you don’t want to buy the products.
Pipes that have been treated to handle lower or higher temperatures and higher pressures may be worth it if there is a chance they’ll otherwise fail.
