Final answer:
A siphon is the pipe pattern that supplies water to hydrants from more than one direction.
Step-by-step explanation:
The pipe pattern that supplies water to hydrants from more than one direction is called a siphon. A siphon is a type of pipe used to convey water through an area that is higher or lower than the beginning and end of the siphon. It allows water to flow uphill or downhill, enabling hydrants to be supplied with water from multiple directions.
