an even better way is to run a float valve in the sump and use your RO only to fill a header tank
I disagree, because this will not shut off your waste water production, because it doesn't control the water source to the RODI unit. If you just install a float valve, you will continually pump waste water down your drain.

For a float valve system, you need a hydraulic valve plumbed into the RODI (comes with some RODIs like Aquasafe I just learned).

I bought a hydraulic valve for my AquaFx unit, and it failed, because my output line is long, and the pressure build-up never got high enough to trigger the hydraulic valve. This is why companies like spectra-pure make pressure bladders to install.

I have seen setups like yours fail quite often
How did they fail exactly? I would rather rely on an electric solenoid than a pressure activated switch any day.

setting up something this elaborate for a tank that is supposed to be up only for a couple weeks is nuts
I doubt you are setting up a reef tank for only a couple weeks and then tearing it down before it has even cycled, so buying the equipment and setting it up is not crazy, because you can use it on your reef for a long time. Plus it obviously isn't crazy, it would have saved your live rock, and it would have paid for itself many times over in wasted salt and dead frags.
