RODI Temp question

Marchillo · 06/18/2015, 06:06 PM

So I just read an old disturbing thread.

I make my water in a bathroom sink my attaching to a faucet. I turn the faucet on to get to around 75 degrees and check frequently to make sure I don't go above 78 degrees.

I just read you shouldn't do it this way. I've been doing this for almost 6 months. My TDS meter reads zero still. But sounds like I'm doing this wrong. Should I just have it turned all the way cold? It's a single handle faucet that doesn't distinguish hot/cold.

I don't want to tap into pipes. Id change the faucet if need be. But if the water going into the system is 75 degrees or less what is the issue? If I caused harm to the unit wouldn't my TDs read higher than zero? If I use really cold water there will be a lot more waste and take a lot longer.

Thoughts?

Thanks for the advice.

Steve.

Hot water can have dissolved solids in it but you have an RODI unit and a TDS meter...you're good.

Ok great. My TDS coming in is super low too. It ranges 19-29 entering the unit and comes out 0.
