Best bang for Ur buck ATO

auto shut of valve/solenoid and a float valve from Kent worked well for me for over 10 years

+1. Best bang for the buck, for sure. I have a rodi line plumbed directly to my tank using this. Completely fail safe and trouble free.

same here. Ro line plumbed direct to sump, on a float switch. never had a failure yet.

The new Hydro one seems pretty good so far and is cheaper then most other options mentioned but you have to supply the pump but likely have a maxijet or similar lying around.

I like that the controller is water proof or at least water resistant. I spilled water on my tunze controller once years ago and that was it. It is probably still the best in that you take a few ml out and it comes on. The hydro one there needs to be a very slight drop in water level but more significant. Not enough to effect salinity but I don't think its coming on anywhere near as much as a tunze or jbj.

The JBJ seems pretty good too, I also use one of these on my pico. I recently had a sensor die for no apparent reason but it was going for several years and since I only use one I simply swapped it for the other one and its back to working great.

Really any option is better then manual.

So your RODI runs for short bursts to top off your system? Usually not a good idea due to TDS creep. RO systems work most efficiently when used in longer runs, not short 5 minute bursts. I know you guys on the coast have pretty low source TDS, so might not be an issue. I would never do that here with a source TDS in the range of 180. It takes a good 3 to 5 minutes to get the the RO output TDS down to 1 from 20 or more on initial start up. And if I ran that 20 TDS on start up through my DI stage with multiple short on/off cycles on a continuing basis, it wouldn't take long to exhaust the media. Without the DI stage I'd be adding unwanted TDS to my tank in pretty short order.

I have a DI stage (which is what goes down to my sump), and my final output is always 0 or 1 TDS (have an inline dual TDS gauge showing after RO and after DI final water). Also my RODI has an ASOV, to reduce wastage, and pressure storage tanks for the RO water, so I always have a ready supply. We have a kitchen RO faucet too, which is used all the time. Have not had to change my membrane for 5+ years, and DI is 2+ years, and still good.

Can I +2 this? Same here, works great.

If I send ro straight to my sump via a float doesn't this mean the rodi will continuously generate waste water?

Only when it's actively topping up. No different that manually filling an ATO unit.

a very generous member on here just gave me the jbj for free but its missing float switches. Can i use these from jl on them or can i order a better one somewhere? http://www.jlaquatics.com/phpstore/s...ct_ID=da-zfsk1

also can i just use a aqualifter with the jbj?
