The answer is a big NO. If people say PVC and CPVC pipes are safe, they are not telling the truth and came under the influence of plastic industry’s ‘lopsided research’ and information provided. Read here why… PVC and CPVC pipes should not be usedPuhui Pipe manufacturer in China
Why (and how) to avoid PVC productsPuhui Pipe manufacturer in ChinaWhy go to all the trouble to avoid toxic PVC (vinyl) plastic? Lead. Phthalates. VOC''s. Dioxin. Just for starters. It''s nothing to mess around with, especially considering that these chemicals are well-established carcinogens and endocrine disruptors that wreak havoc on growing children. We''re talking about developmental damage here, as well as damage to Puhui Pipe manufacturer in China
Roughly half of the world''s PVC is used in municipal and industrial pipes. In the U.S., 66% of the water distribution pipes and 75% of sewage pipes are constructed from PVC. In addition, PVC pipes can be easily fused together to create permanent and virtually
We all expect our drinking water to be clean and safe, but a new article reveals that PVC drinking water pipes may be carrying an unwanted contaminant into our precious drinking water: toxic lead. Yes, the very same lead that can permanently damage the brain.

The contact of deionized water with various PVC pipes for three successive test periods of 24, 48, and 72 h duration has been made. Twenty water samples were collected from houses within Medina Al-Munawarah residential area and were analyzed by using solid phase extraction, followed by high resolution gas chromatography with flame ionized detector (GC-FID).
PVC pluing pipes are not just used for cold and hot potable water, but for sewage appliion as well. It is easy to install and easier to work with than the traditional galvanized HDPE pipes. Diameters and NSF/ANSI standards are clearly marked on these pipes to show its compliance with a sizing tool, as well as with the health effects.
- In standardised pipes for potable water (EN 1452) the expected lifetime of PVC pipes under pressure is extrapolated based on hoop stress testing of pipes for up to 20000 hours. This allows an estimation of the durability by extrapolation to a life expectancy under pressure of 50 to100 years.
