I just got a new 6 stage RO/DI unit. I'm a little confused on output. I would like to take the output to a small pressurized holding tank, that would then go to a float valve for ato. I'm not sure I get how to do this though...? There is only one output from the DI unit, and just one input on the holding tank. I'm sure I'm just being dumb and missing something. Thanks!

If I understand correctly...
Place two T's in the pure water output line. Run a line off to the holding tank and another to a valve that can be opened manually to fill buckets/etc. for water changes and water for plants and etc. Smile When the float valve and manual valves are closed the water will get pushed into and fill up the pressure tank. When either valve opens the pressure tank will push water out.

Is there an automatic shut-off valve on the unit? When the output pressure reaches around 12 psi the auto shut-off valve shuts down the water at the input source. That's important for extending the life of the float valve.

Thank Mark, I think I can visualize that.
