How this service works
Water held in a run of pipe in gallons and litres per foot and in total, from nominal size or inside diameter.
Output
Returns gallons per foot, litres per foot, total gallons, total litres, total cubic inches, cross-sectional flow area in square inches, inside diameter in inches, and seconds to purge the pipe run at 1 GPM, along with the pipe description and an optional summary or disclaimer.
Example use cases
Freeze-protection antifreeze sizing
“I need to know how much water is in a 40-foot run of 1-inch copper Type L pipe so I can figure out how much glycol antifreeze to add — what's the total volume in gallons and litres?”
Pre-repair pipe drainage estimate
“Before I cut into the pipe, tell me how many gallons are sitting in a 25-foot run of 1/2-inch copper Type L pipe so I know how much water to drain out first.”
PVC irrigation pipe volume check
“What's the total volume of water in a 100-foot run of 3/4-inch PVC Schedule 40 pipe, in both gallons and litres, and what's the gallons-per-foot figure?”
Technical details
Endpoint
GEThttps://plumbing-calc.x402tookit.com/pipe-volume?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to know the water volume held inside a specific pipe run — for tasks like antifreeze dosing, purge time estimation, drainage planning, or heat-loss calculations. Prefer it over manual lookup tables when the user specifies pipe length and nominal size or inside diameter. It handles both copper Type L and PVC Schedule 40 nominal sizes. If the user needs pressure loss, velocity, or pipe sizing instead, use the sibling endpoints on the same platform.
Side effects
- Missing required lengthFeet parameter returns an error
- Unsupported material string (not copper-l or pvc-40) may return an error or default
- Providing both nominalSize and insideDiameterInches may cause ambiguity or one being ignored
- Non-positive or zero pipe length may produce invalid results
- Unrecognized nominal size string (e.g. typo) may return null pipe data
