    You can build your own sprinkler system for a fraction of the cost of expensive, commercially installed systems.

    Equipment list:

    3 or 4 impact sprinkler heads and the aluminum spikes they attach to.
    Enough garden hoses to go between them.
    One additional hose for the loop. This one needs to be as long or longer than the other hose lengths added together.
    A T-connector with all three outside diameters (OD) matching the inside diameter (ID) of your hoses.
    3 screw down hose clamps to fit the hose OD.

    Assembly:

    Remove the screw-on caps from each spike. Attach a sprinkler head to each spike top and tighten securely.

    Screw the male hose end into the female connector on one side of the first spike. Screw the female end of a second hose to the male side of the first spike. Screw the male end of the second hose into the female end of the second spike. Continue until you have connected all of the spikes together.

    Connect the female end of the last hose (the "loopback") to the male connector on the last spike. Cut the first hose in half, and cut off the male connector from the loopback hose. Insert the top two ends of the T-connector to each half of the first hose and insert the cut-off end of the loopback hose to the last end of the T.

    Set your sprinkler heads where you want´em in the lawn, connect the hose to the water faucet, and let´er rip. The loopback hose helps equalize the water pressure between the sprinkler heads. If you only use two heads, you may not need it. If you use 3, 4 or more and the last head barely trickles, the loopback insures even distribution.

    Hope this is helpful to someone...anyone...everyone...it was helpful to me!!

    It's been suggested many times; the prime mover is a member named Kiril, you might PM him for his insights. That's a pic of one of
    those systems in my avatar.

    Wow, now that really is helpful. All the time I've wasted trenching and burying pipe, when I could have put this type of system in...

    Should have put this post on the Homeowner Assistance forum - Lord knows they need a pro like Workhard to help them out.

    Are "impact sprinklers" the same thing as "throw heads", or are they "fountain heads"?

    Wow! I guess I never should've taken those classes on proper design and troubleshooting. If that's all a sprinkler system needs to be, hell I guess I'm out of a job.

    Oh Yes, I can see this technique working in my areas that charge out the wazoo for potable drinking water. And sure works well on a three acre turf site too.
    Also sounds a sh1tpot easier than pulling water from a lake 1100 linear feet away with an elevation change of 185 feet.
    I can just see my client's face, "Yessir you owe me $12,000.00 for this technological wonder" and then tell them the hoses are covered under warranty from blade damage.

    Just received notice that we were low bidder on a 9-acre school project: 7-1/2HP sub pump producing 110GPM@70PSI.

    Think I should use bigger hose for the mainline?

    On a big project like that , you definatly want to go with 2 garden hoses.

    I'm thinking I'll need that 3/4" heavy-duty contractor's hose with the crimp-on fittings.
