New RODI System

Glott3133 · Mar 25, 2020

I just purchased an RODI system, so I definitely don't have many answers. Before I begin setting it up, I don't believe I have enough tubing to connect to the ATO float in my sump, and to the water supply line in the ceiling. So I have 2 questions - 1. Can I just go to Lowes/Home depot and purchase additional 1/4" tubing? 2. Where can I purchase a quick connect Y-connector?

Thanks

Yeah most of your hardware stores will carry it

Home Depot will definitely have the RO tubing and they will also carry a bunch of John Guest fittings. If they don’t have a Y connector they’ll probably have a T.

Do you plan on hooking the ATO float in your sump directly to your RODI unit? Just a word of caution if you are... if that ATO float ever gets stuck in the open position, you may be looking at a serious flood hazard.

In addition, having the RODI unit constantly cycling on and off will cause you to deplete your DI resin at a much faster rate due to TDS creep as opposed to making larger volumes of water in batches and using a DI bypass valve to flush out TDS creep water upon system start up.

Thank you for the info. Are there any good posts on what to do and how to do it. I definitely don't want to have a flood situation.

I make water in large batches and store it in a couple of 20 gallon Brute trash cans. I keep top off water in a 10 gallon ATO reservoir beside my tank and manually fill it up as it depletes. I don’t trust gravity fed float valve used to top off water so I use a dedicated ATO unit. I trust the Spectrapure ULPC-ATO, the Tunze 3155 or the Avast ATO as they have a long trackrecord of reliability.

As far as using a DI bypass valve to prolong the life of your DI resin, here is a post I made on the subject in another thread awhile back...

RO/DI - Are all equal?

Quite frankly, the only thing you need is the vertical DI kit. You already have everything else. Based on your numbers though, I do think you need a new RO membrane.
