Picture of A Three Head Sprinkler for Odd Lawns
This is my first Instructable, so be brutal.
My idea was inspired by bwpatton1 and his “Simple Garden Sprinkler out of inground popup sprinklers”.  He mentioned that he intended it as a springboard, and I jumped all over it.

My yard has several areas that are too big to use a soaker hose on and too oddly shaped to use an oscillating or rotating sprinkler without multiple moves. I wanted an easy way to evenly water these areas that could be adapted to other hard-to-water spaces.
My goals for any project and Instructable are simple:
Low cost (if you have money to burn, please donate to my early retirement fund)
No parts made from unobtainium (a rare element that is either very expensive or only found in a single store in Outer Mongolia, and it's on back-order)
Simple fabrication (use common tools, no tool-and-die machinist certification required)
Fill a need (okay, sometimes I like to tinker for the sake of tinkering)

I think I achieved all of my stated goals with this project.

Step 1: Materials:

Picture of Materials:
The parts for this build were all found on two aisles of my local big-box hardware store.
Qty   Desc
1  x  3/4” x 10’ PVC pipe, Sch 40
6  x  3/4" PVC cap
5  x  3/4" PVC tee, slip x slip x slip
3  x  3/4" PVC tee, slip x fpt x slip
1  x  3/4" PVC 90° elbow
5  x  3/4" PVC adapter, slip x fpt
3  x  1/2" thread x 3/4" mpt (next to the sprinkler heads; this converts the 3/4" PVC threads to the 1/2" sprinkler head threads, which is not the same as 1/2" PVC threads)
3  x  2.5" popup sprinkler head, 180° pattern
5  x  1/2" insert x 3/4" mpt (next to water heater and sump pump items)
5  x  #8 hose clamp
1  x  5/8” garden hose (cheap, it will be cut up)
Teflon thread tape
PVC primer and cement
Total cost for the materials was about $25.00.

Thanks for the plans! Just built these today. The only issue I am having is the 1/2" insert/barb is too loose for a 5/8" hose. Water shoots out of the end, even with the hose clamp tightened all the way down. Going to either find some new fittings or try 1/2" ID vinyl tubing.

Also, anyone building this, be very careful cutting PVC on a miter saw. I had a couple pieces of PVC explode and the plastic shavings are a pain to clean up.

This is ALMOST exactly what I am picturing to do but I had NO clue what so ever on what fittings to use...

I really appreciate you listing the parts and most importantly the thread sizes/reducers!

I didn't want to spend $1,200 on a sprinkler system for the front lawn which isn't huge by most people's standards, I really only need 2 maybe 3 sprinkler heads tops... I think I am going to modify your layout just a little bit but using the spikes as someone recommends. That way I can spike it right next to or beside the bushes so it's not actually "sitting" in the lawn and the shrubbery will hide it to the naked eye.

I am debating using the hose method that you have and just putting mulch over it so you can't see any hoses, or doing the pipe method and also covering or possibly digging them into the ground a little bit...

Is it recommended to have the sprinkler head directly above the pipe like you picture or can it come off a 90 degree fitting? IE: I have a piece of straight pipe going parallel to the ground, then a 90 elbow fitting bringing the sprinkler head perpendicular to the ground so it can spray as if it was "buried" in the ground?

Hope that makes sense.

Love this community! So many ideas!



Great job on your first instructable.

Very nice!

This could be greatly simplified by substituting metal sprinkler spikes for the PVC fittings. See this link for an example spike. That's what I used wherever I needed to place a pop-up sprinkler on grass. I used a similar setup to yours when I put them on concrete (to facilitate mowing).
Bad Link

So, this is not found everywhere (one of the original points)

Yes, that might have simplified things a bit. On the other hand, the spike is not always a good option. I have a commercial sprinkler that has a spike base, and to set it in place I have to make a pilot hole in the yard with a hammer and a big screwdriver (the subsoil contains a lot of clay). The bases I made allow me to reposition the sprinkler heads by simply pulling on the hose and sliding the heads where they need to go.

I think you meant 6 x 2" lengths and 5 x 3" lengths right?

Love your sprinkle base. This solved a problem I had. I had three sprinkler heads that were originally on aluminum spikes. The aluminum corroded and broke making them useless, but the heads still worked. I made a slight modification to yours, I changed the end Tees to elbows and feed the water in one leg and out the other. This also eliminates the end caps. This will lower the cost slightly, and works just as well. My heads have 1/2 inch male threads so I used a PVC reducer in the top of the Tee. Also there is no need for thread sealant of any kind and just hand tight will work. After all if it drips a little it is just going to add a few drops to the yard. I am including a photo of mine.
Thanks for the idea.

Thanks for posting your design and for the kind words. I would not have thought to lay out the supporting legs like that, but it looks like it simplified construction. I like it! My sprinkler is still going strong, but if I have to replace one of the base units, I think I might give this a try.

That is what I love about this community. I got an idea from one person and modified it, and you took that mod and created your own version. Ideas evolve and grow each time this happens.
An interesting project. i think it would be more practical not to use cap on the two side pvc and use the hose fitting. In this configuration, you could have more flexibility in the position of the sprinkler. I don't know if I've well explain my idea, but if you need more explanation, just contact me.
kebmoore (author)  jasongroupindustries4 years ago
Flexibility was a consideration, but cost overrode that. The hose fittings would have almost doubled the cost of the materials.
oh, yes, I didn't thought about the cost aspect.

I thought a lot about the design before I created this. My wife teases me about planning and re-planning things, sketching different designs and taking my time. In this project, all of the planning work paid off when I was able to cut the build time and the material cost to the bare minimum.
yeah, i agree wit you, planning is best way to achieve the best result.
