ATO system

[tankedchemist]

So, my previous cheap ato system (float valve and a back pressure thingie that connected to the RODI unit) failed catastrophically several weeks ago. I'd like to find something more fail-proof so I don't have to worry about problems when I'm away at a conference this summer.

What do you all think of this: SpectraPure® U.P.L.C. Ultra-Precise Level Controller

I'm sure that would work fine. I use an ATO from autotopoff.com. It only cost $50 complete and you just need to use your own powerhead to pump the water into the sump/tank.
