There is no heavy metal additives in PVC-U water pipe and it would not be covered with dirt or contaminated by bacterium.
■ High Flow Capacity
The smooth interior walls and low friction of PVC-U water pipe result in low flow resistance and high volume. 
■ Corrosion Resistance 
PVC-U water pipe is non-conductors of electricity and unaffected by 
electrochemical reactions caused by acids, bases, and salts that cause 
corrosion in metals.
■ Low Installation costs
PVC-U water pipe is lightweight and is installed with solvent cement,
 thread, flange, and gasketed joint. Ease of installation reduces the 
installation costs
■ Longevity
PVC-U water pipe can work for more than 50 years under proper use.
■ Environment-friendly
PVC-U water pipe can be recycled.
