Do plumbers still use copper pipes?
No longer is copper piping the primary, or preferred, choice of most homeowners and plumbers .

Is ABS pipe still used?
Acrylonitrile butadiene styrene ( ABS ) and polyvinyl chloride (PVC) are commonly utilized as pipe building materials since they are both non-toxic and abrasion-resistant. Once formed into pipes , these materials are used throughout the construction industry for numerous purposes.
Is it safe to drink water from old galvanized pipes?
Although galvanized (zinc-coated) pipe is still considered to be a safe transport material for drinking water , there are some potential health concerns if the water supply is corrosive due to its acidic condition (low pH).
