(not sure if this is the right forum...) Hi guys, Finally getting around to getting a RODI system (had to wait until my RO water cooler/heater contract ended). Before I even get into which RODI system to get, I've got some questions about installation. Sorry in advance if some of these questions are stupid, and of course tia for your responses. Couple things in advance: I want to have RO water filled into a pressurized 5 gal tank under the sink for RO water via a sink faucet AND have RO water run into my refrigerators water/ice maker. RODI water will fill a large tank in the garage. The RODI system that'll eventually fill up a large water container in the garage: - Is the setup different for a "fill as you go/need" setup vs a automatically filled container with an ASO (is that even the right acronym for automatic shut off?) sensor installed? - Is there a limit to the length/distance I can run the 1/4" rigid tubing? Can it travel up and down? - I'm contemplating where I should install the RODI... a) in my garage. My water heater tank is in my garage. Is it difficult to tap into the line going into the water heater? If not, I would have the RODI there, filling my water container in the garage. I would have to tee off the RO water into my kitchen (about a 15-20 ft run to the bottom of sink and 10-15 ft to fridge). Can I just tee off/split the RO water line into 2??? b) under sink - this might be the easiest as I could probably re-use some/all of the water connections that are already there feeding my RO Water cooler/heater. If I could install the RO filters and 5 gallon tank under the sink, then I would need to run it from there to the fridge and the DI filters in the garage. Or just install the entire RODI under the sink, run the RO in the tank and fridge, and run the RODI to a tank in the garage... - how is the RODI water output controlled? is it just a valve that can be manually turned or automatically via a aso sensor? Sorry for super long post.... I'm fairly handy, work on mostly everything in the house, but plumbing is probably what I'm least experienced at... Want to do as much research ahead of time as possible and make sure I order the right parts needed as well... Now to start looking into which RODI system to buy... I see some people with 4, 5, even 6 canisters. Are the extra canisters worth it? I'm ashamed to say I don't know what TDS my tap water is... I live in SoCal, just north of LA in Valencia/Santa Clarita... know I have very hard water, but does that necessarily mean its high TDS water???
