Default Two sprinkers: connect in sereis or parallel?

I have a lawn geometry that is best handled with two sprinklers.

Would it best to connect them in series (faucet to 1st sprinkler and
then 2nd sprinkler to the 1st one), or parallel (put a Y splitter at
the faucet and connect both sprinklers independently by separate
hoses)?

Thanks.


With a series arrangement the pressure will drop going down the line which
means that if the sprinklers are the same the one close to the tap will
theoretically put out more water than the one further away. Whether or not
this is important in your case I cannot guess. If your water pressure is high
and the sprinklers are low volume you may not even notice the difference.

With the parallel, if the sprinklers are the same, and the length of hose from
the Y to each is the same, they should put out the same amount. This
arrangement has some flexibility as you can put in taps to adjust the flow in
the two arms.

There are other theoretical considerations (eg relative height from the tap)
that could make a difference but which may not be important in practice.
Which uses more hose depends on the geometry.

Not knowing your situation or how important even flow may be to you makes it
hard to be specific.
