is upvc pipe safe for drinking water

For commercial or residential purposes, picking the right kind of pipes usually brings up one common question: Is uPVC pipe safe for drinking water? The answer is positive, but only if relevant safety measures are met. Water supply systems using unplasticized  polyvinyl chloride (UPVC) pipes are widely employed due to its non-toxic and lead-free as well as being chemically resistant. Not all uPVC pipes are created equal. The safety of uPVC pipes depend on the existence of national and international standards for the pipes concerning drinking water.


The focus of this article is the safety compliance checks and regulations and certifications relevant to the safety of drinking water while providing tips on how to select the right uPVC pipes.

Comprehending the Safety Compliance Standards of uPVC Pipes

Governments and regulatory bodies set strict guidelines to ensure uPVC pipes are non-toxic, durable, and suitable for drinking water. Here are the key standards you should look for:

1. Certification from Bureau of Indian Standards (BIS) - IS 4985 & IS 15778


For India, the BIS certification guarantees that a uPVC pipe wholesaler provides pipes that meet selective quality and safety standards set by the government. Two important certifications to check are: 

  • IS 4985: Covers pressure pipes used in a drinking water supply. IT ensures pipes do not contain harmful things like lead, cadmium, and plasticizers.

  • IS 15778: Focuses on CPVC (Chlorinated Polyvinyl Chloride) pipes that are prevalent and frequently used in the hot and cold water systems. 

If you’re buying from an upvc pipe manufacturer, always ask if their products meet these standards.

2. NSF/ANSI 61 Certification (USA)


For any pipes that are exported to or used within the United States, NSF/ANSI 61 certification is obligatory. This is a public consensus standard which sets the fundamental guideline for the evaluation of materials, components, and products to ensure that they do not leach harmful chemicals into drinking water through uPVC pipes. The standard permits both testing and certification of products against its criteria.

 

3. ISO 4422: International Drinking Water Standard


The certification confirms the compliance of uPVC pipes with international safety and performance requirements. This certification is essential for manufacturers who export their pipes internationally.

4. WRAS (UK) & AS/NZS 4020 (Australia/New Zealand)

  • WRAS certification verifies the compliance of pipes with the United Kingdom's guidelines for the safety of drinking water.

  • AS/NZS 4020 outlines Australian and New Zealand standards for the testing of plastic pipes intended for use in drinking water systems. 

How to Ensure You’re Buying Safe uPVC Pipes?

Check the Manufacturer’s Certifications

Always buy from a trusted uPVC pipe manufacturer that meets national and international safety standards. Look for BIS, NSF, ISO, or WRAS markings on the pipes or packaging.

Opt for Lead-Free uPVC Pipes

Some manufacturers still use lead stabilizers, which can leach into drinking water over time. Go for pipes explicitly labeled "lead-free" to ensure safety.

Verify Material Quality

High-quality uPVC pipes should be:

  • Odorless and tasteless (no chemical leaching)

  • Resistant to UV radiation (prevents degradation)

  • Strong and durable (no easy cracking or warping)

Look for UV-Stabilized Pipes for Outdoor Use

If your plumbing system involves outdoor installations, choose UV-stabilized uPVC pipes to prevent sun damage. This ensures the pipes last longer without affecting water quality.
