Copper Pipes Q & A
Q: How do I prevent copper pipe corrosion?
A: Use dielectric unions when connecting to dissimilar metals and ensure proper pH balance in water.
Q: What's the price range for copper pipes?
A: Prices vary by type and diameter, typically $2-$8 per linear foot for Type L.
Q: Can copper pipes freeze and burst?
A: While more freeze-resistant than PVC, copper can burst if water freezes. Insulate pipes in cold climates.
Q: How do I identify quality copper pipes?
A: Look for smooth surfaces, uniform coloration, and proper ASTM markings.
Q: What's the lead time for orders from China?
A: Standard production takes 15-30 days plus shipping time (2-6 weeks by sea).
