pipe layout and pressure...

IMO, B is always best if it is achievable. Not that it is always going to be necessary, but It definately will help with more equal pressure. Whether you're building a drip manifold or for what you're doing

You fucker, I was going to say A lol. A is how I had mine. The "fork" layout. Less pipe =more pressureIMO, B is always best if it is achievable.

Though B is more durable and easier to handle when you move it or whatever. But, with 1 pump, equal pipe distance and sprayers spaced evenly, I think (but don't quote me) that A will give you a little more pressure, but all equal. On a long run of pipe, you'd see more pressure, on a short run of pipe, I don't think you'd notice.

I have had the "Fork" layout and I can tell you something right now. DONT DO IT. I will never do ANY system with a fork layout ever again and will only do looped systems
You: But why Daggy, please tell us
Me: ok
If you run the fork setup there will always be less pressure at the fittings by the cap. Wont matter if you up the pressure with a bigger pump the fittings closest to the pump will always have more pressure than the ones in the back. With a looped system the system holds a consistent water pressure all around. Hope that made sense.

That's crazy, I got the opposite on my Aero build! I'm also getting the opposite on my closed loop dtw manifolds. The ones closest to the pump get about 1x more water while the ones at the end get 1/2 the water, when I measure with a cup. What gives?!

The only thing I can come up with is too little pump power? Could that be it? I had a 1200gpw pump for my Aero system, but it wasn't quite enough, for a 4x4 system. The fork produced much more power at all spray heads though.

So you get uneven flow with the closed loop?

I tried a few different layouts, I think it's the extra turns (elbows) that slows the flow down. I'm sure if the pump used is bigger than needed it might be hard to tell, depending on the design. But most people use the wrong size pump, it just happens, and the fork layout seemed to work better in that case. The micron of the drip heads could also cause a different out come. There's just so many variables. But I think, just my opinion and I can't back it up other than trying a lot of different layouts, that the fork worked better. Even better the H layout. I feel each elbow slows and restricts flow. But I also feel with enough pump power, booster solenoid etc, it would be minor noticeable difference. There's just so many ways to lay out the pvc and so many different pumps and mister heads.

If you think of the water flow as driving a car, you slow down at the turns. I'm not a plumber or aeroponic expert, that's just how I noticed it. I only had 2 full runs on my hpa system. Lpa may be different.. Then again, in my Aero cloner machines I built, I do close the loop! But it's just been because I had t's and elbows, and no end caps lol. They do the job but I still think if I made them with end caps, I'd get more pressure. God, this picture goes against what I'm saying, but I built it. It works. This is lpa cloner with the plastic heads, it works better with end caps though

Oh, and yes, uneven flow occurs by the elbows, both in the dtw and cloners I have closed loop, could be by pump size though. I'm going to build the dtw manifolds a bit different to see if that helps, I'm still learning after 10 years of messing around haha

Ok so we have a different build design. I went with a high pressure pump and metal misting nozzles. The problem with a pump this is 1200 gph is they put a lot of water out, but don't have any PSI. I had a 550 gph pump that was like .1 psi or something. it did nothing when they hit my nozzles, it just kinda leaked out a little. so you will have problems with lots of elbows and tees losing what little pressure there is. However with the nozzles like above, they are designed for low pressure so they will get the water flow you are looking for. I am super excited to be cleaning out 50 nozzles every week when they clog. yeah me...

That looks like a nice lower micron water bead! Do you have low micron pre filters to prevent your clogging? The one thing I know about aeroponic, is clogs could be routine, and a good pre filter is a must mang.

To note, you'll probably shit your pants at the growth of the plants if you keep those nozzles clean it's unreal! My first two full test runs with aeroponic I got an oz per plant, 36 plants, a lonngggg time ago when there were no bells and whistles. I can't imagine how it would be today. Keep that baby rolling and you'll be happy

Oh, to note, the celluloid booster and everything in you're system looks similar to the one I ran, 1200gpw, booster, metal 50 micron mister heads etc. Those mister heads won't do anything with out psi. But for the plastic ones, in my lpa manifold pic for my cloner, that only uses a 360gph, plastic heads 310 degree I believe. It does the job.
I hope you're system is working well, get the pre filters stat!

Add 1 more pump with a Tee on it that splits to hit between the 2nd and 3rd and 1st and 2nd manifold?

buy one of these...
its a shurflo 8000, its a 110v and pumps at 100 psi.
