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.


How did they fail exactly? I would rather rely on an electric solenoid than a pressure activated switch any day..

first of all What are you talking about??? Me things you need to re-read what I have set up. My RO is not on continuously, only about 4 hours a month on my main set up. what I have is a RO which I turn on once a month to top off my reservoir, then it is shut off. the top off for the main tank enters the sump from the reservoir through a float valve Via a Kalk reactor. so when the float is up there is no water entering the sump when it is down it allows water to enter. there are no electrical solenoids or pressure valves in the system. it is the tried and true method of controlling the level in your sump, and only takes about 5 min of maintenance about once ever couple months (If you don't use a Kalk in your make up water, it doesn't even take that.

what are you taking about again... cycled??? I took cycled rock and water from my main tank and put it into a holding tank, I am taking same rock and putting it into a cleaned tank of new water, there won't be any cycle. if nothing would have come up and I would have been able to do it when I wanted to it would have been two weeks start to finish. So buying the equipment would have been a waist of money as I already have it set up on the reef and after 2 weeks of use I would be trying to sell it at a stupid loss for basically brand new stuff.
