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.

Use the "y" connect. Better water pressure. You'd need to have such high
starting pressure with the series arrangement that the hoses would be
stressed.

If you use a Y splitter, make sure you get one with full sized
passages. Some of them have tiny passages that restrict the flow even
more than it would be just from using the splitter.

This one
http://www.lowes.com/lowes/lkn?actio...68-143-PP25001
works well and is cheap but doesn't have individual valves.

This one
http://www.lowes.com/lowes/lkn?action=productDetail&productId=248108-306-AY2FFMGF&lpage=none
also works well and has individual valves. Note that Gilmour makes
several other y connectors that either restrict the flow or that are
plastic and in my experience leak, so make sure you get the right one.

All of the y connectors that I found at Home Depot restrict the flow
except for one labelled "Goodyear" that busted on me after about 2
hours of use.

Thanks to everyone. This is very helpful. I'll remember to get one with
individual valves for each line.

One more thing: Our tap is not at the edge of the lawn itself but some
distance away. So instead of putting the Y connector at the tap itself,
I could save some hose length by running one hose to the edge of the
lawn and put a Y connector there. Any problems with that?

It depends on two things, hose size and water pressure. Assuming you
are using 5/8 inch hose and have very good water pressure you should not
have a problem putting the Y connector at that point.

If you had an automatic irrigation system you may have six to a dozen
heads on each zone, all in series. With two sprinklers, unless you
have very low pressure and volume, I doubt it would make a lick of
difference how connected... only one way to know, try it each way. I
would probably use the Y connection only so I'd have a valve for each
sprinkler, you probably don't want them each to operate exactly the
same. With auto sprinkler heads they are individually adjustable but
not so with standard garden sprinklers. Often with only two sprinkler
locations it's best to run one sprinkler at a time rather than both
together. And it's more important to choose the right sprinkler for
the job... you might need a different kind of sprinkler for each of
your two sectors. Anyway, how difficult can it be to try a few
different arrangements... hmm, now I'm wondering if you are capable of
showering yourself.

Nope - actually that is the best way. IMHO any way....

Best splitter I ever got was "odd lots" type place. Nearly no flow
restriction and three valves. Can't read any name on it, but since I ID'd
other pieces as repackaged Gardena items.....

Is it plastic or metal? Gardena's tend to be plastic with "grey+orange"
color theme. However, the design *might* have been different in the
past.

Thank God, my family is rich and can hire somebody to shower me.

This is grey (almost a silver) and green. Bought it 15+ years ago...
