I think you might as well go ahead and try. Worst case is that it won’t work and you’ll have to buy 2 more PVC adapters for each valve.
On the top of my indexing valve, there was a little hole. I think this was there to allow the float to move up after a zone was done watering. If yours looks like the one in the link you provided, you might be able to rig something to prevent that.
@outbreak question regarding the manifold you made. Say you had a leaking valve, can a single valve be replaced? Since they are threaded it would lend itself to replacement however in my mockup I dont see how its possible.
I imagine these will eventually leak, although perhaps the leaks really only come from the top diaphram area, which you can easily swap out without modifying the PVC. Do you have any thoughts on this? Thanks
@roach Is your issue with unscrewing the valves because they’ll hit the valve next to them? That was going to be my problem so I just put in a threaded coupler for each one. That way I can pop out the valve without rotating the whole thing and lets them be run closer together.
I figured I’d cross that bridge when I come to it! lol
That coupling, do you use one on each side of the valve? Also the valves I saw at Home Depot were female. Didnt see any male ones, which might be easier. Thanks
In my case, the other end is the 1/2 drip line which has a quick release already at the valve’s output. Otherwise, yeah I’d have put them on either end. Here’s a little better view of how they work. This lets you easily take the whole thing out as a section. In a previous setup I hadn’t done this and had two valves go bad on me. It was really annoying having to cut the pvc while in the box so this time around, I’m trying this.
edit: I should add this is actually a slip union, not technically a coupling (in case you were to search for one)
Man…you were holding out on us!!! I see how it is! 
Awesome, will def look into this. the LAST thing I want to do is spend a day replumbing all this crap, only to have a valve die on me 6 months down the road, and have to tear it all up again. This looks like it would help.
BTW why does it look like your valve has 2 solenoids? Is that for the drop line?
Thanks
Thanks guys, got everything installed this weekend. Ended up using the Orbit manifold and so far so good. Will post pics today or tomorrow. Took a bunch! Also, zero water hammer 
Had a small leak from the anti siphon unit but going to monitor to see if I need to replace. The valves and the anti siphon unit are above ground so any future work shouldnt be nearly as hard. Took my dad and I about 10 hours total to dig up the area, plumb 6 new lines, and the manifold, as well as the wiring. Moved the wiring from the outside, into my garage. So far so good.
I do have an issue where the Iro doesn’t like my wifi password, even though it isnt crazy complex. I temp set to something super easy and the BlinkUp thing worked just fine. Hopefully can go back to my more complex password sooner than later
Nice! Looks like a tight fit.
Oh and while we were at it, we replumbed some of my pool pump piping, and used a Union like you posted @cfwiggum . I love that thing. Will make future maintenance super easy
I really like the way the pipes overlap. It made a cool looking pattern.
Looks great!
Thanks guys. Def appreciate the photos and advice along the way. And even though he wont ever see this, gotta thank my dad (guy in the pic) for the awesome help.
Oh and I got the wifi issue resolved. Ended up trying on an iphone instead of my Android and it took just fine. A bit irritating that it works better on iphone but I happen to have one to use for a few so it worked out. So cant complain too much!
You have me re-thinking my setup now! Yours looks much more user friendly!
So this post is two years after the fact but I just felt the need to chime in. My name is Chris and I am the general manager of FIMCO Manufacturing. Yes, we manufacture indexing valves and have for 55 years. I believe the reason people use them is their simplicity and the fact that truly all you need to work on them is a phillips head screwdriver. I really like my rachio controller for my indexing valve and recommend it all the time to anyone who is fairly savvy with modern technology. I myself had to contact rachio’s support and they were extremely helpful. High marks for their support.
Should you decide to go that route or have any questions about indexing valves or how to set them up with the rachio controller I can certainly help. Please give me a call at our manufacturing facility in Jupiter, FL.
I am not trying to tout my valves here and I hope this doesn’t violate some sort of forum agreement. I simply want to help people connect the dots should they need to. As I stated before, I am a big fan of the rachio controller and have one on my residence with an indexing valve.
