Offset on hydrant line refers to a deviation from the straight line of the pipeline.

• Offset is used to avoid obstacles or to change the direction of the pipeline.

• It can be achieved by using elbows, bends, or fittings.

• Offset should be kept to a minimum to avoid pressure drop and flow restriction.

• Proper calculation and design of offset is important to ensure efficient and safe operation of the hydrant line.
