Choose the largest possible line diameter. Despite unavoidable bottlenecks on the line, it is disadvantageous and associated with considerable pressure loss if a smaller overall line diameter is used. Example: the pressure loss of 1/2" lines is 5 times higher than that of 3/4" lines.
The more bottlenecks, the higher the total pressure loss. Therefore, avoid the number of bottlenecks.
Bottlenecks at the beginning of the pipe slow down the water considerably more than bottlenecks at the end of the pipe! In fact, increases in cross-section immediately before a lawn sprinkler hardly show any measurable improvements and therefore do not need to be taken into account, whereas bottlenecks at the beginning of a pipe (e.g. small tap, small pipe cross-section in the house) have a greater effect on the water output.
