How can one water pipe supply several sprinklers?
A sprinkler system can send water from one pipe along several routes. A branch is a place where the pipe divides. Each smaller route can lead to a sprinkler head, the part that sprays water.

In this picture, one supply joins two branches. With water arriving and both routes open, both sprinkler heads can receive water. The branches share that supply; they do not make more water.
A valve can close one branch. Water then cannot follow that route to its head. The other open branch still has a path from the supply.
About this explanation
Starting knowledge: Follow a joined route and distinguish an open valve from a closed one.
