Not a problem. Before you use any of the water, check it with a tds meter.

Make sure that the system you get doesn't use GAC as a prefilter, has vertical refillable DI. You should avoid a self piercing needle valve as a supply fitting. And make sure the system is plumbed such that RO water from the pressure tank never makes it to the DI. There are lots of...

I'm more than a little biased when it comes to recommending a brand of RODI, so I'll sidestep that question in hopes of avoiding a commercial post. The pressure tanks are designed to hold RO (not RODI) drinking water. There are some issues with using these tanks with an RODI system - I can go...

You really have two issues with that piece of hardware: 1. You are missing the two or more adapters that will allow you to hook it up to most sinks, and 2. It has a barbed fitting that doesn't work well with the "hard" tubing used on RODI systems. Rather, you want one with a compression...

The plastic tubing used on RODI systems is measured by OUTSIDE DIAMETER. So the OD of 1/4" LDPE tubing is....1/4". Most of the residential scale RODI systemd use 1/4" tubing. Russ

Remember that everything past (downstream) of the outside of the carbon block is dechlorinated. RO membranes and DI resin beds have a tendency to develop microbial growths - this is where the suggestion to sanitize your system at least once a year comes from: Russ

Hi Angie. Here are some things to look for in a good system for this hobby: No more than 4 stages (sediment, carbon, RO, DI) unless you have specific water quality issues you want to address Standard-sized prefilters, membrane, and DI cartridge Brand name, high-rejection membrane...

We recommend folks stear clear of these saddle valves as a way to get feedwater to their systems. You can read the full write up on our Facebook page. Russ

Not typically necessary. Russ

Considering how you took your TDS measurement, the 18 ppm probably isn't accurate. Russ

From our FAQ's: In this hobby we measure Total Dissolved Solids in parts per million, or "ppm." We often try to measure TDS down near 0 ppm. Because this TDS level is so low, we have to keep in mind the sensitivity of the meter used to measure it, and the technique used to measure the tds...

You can lengthen the useful life of your RO membrane if you put the system AFTER the water softener - supply softened water to the RODI system. Russ

Ideally you check/monitor the TDS in three locations: 1. feedwater 2. RO water 3. DI water You use Nos. 1 & 2 to calculate your rejection rate. Compare that to the factory spec rejection rate for your membrane so you know how well your membrane is working. So for instance, let's say you...

?? I don't understand your question...

Your waste water will have a TDS about 20% higher than your feedwater, but it will have had the sediment removed and the chlorine removed. Russ
