How It Works
Pipe weight varies greatly by material. Knowing pipe weight is essential for structural support, shipping costs, and installation planning. Copper and steel are heavy; PEX is very light.
The Formula
Total Weight = Weight per Foot x Length
Variables
- W — Total weight in pounds
- w — Weight per linear foot (material/size dependent)
- L — Pipe length in feet
Worked Example
100 ft of 3/4" copper Type L: 0.455 lbs/ft x 100 = 45.5 lbs. Same length in PEX: only 6 lbs.
Practical Tips
- PEX weighs 85-90% less than copper
- Support spacing depends on pipe weight when full of water
- Include water weight for structural calculations
- Cast iron is heaviest but best for sound reduction
