how to connect rodi to fridge???

smokinreefer · #1 08-08-2013, 04:11 PM

hey everyone,

i'm wanting to connect my rodi to my fridge's ice maker and water dispenser.

not sure what additional parts I will need.

I understand I need to Tee the line off between the RO and the Di.
- one branch feeding the pressure tank, leading to the fridge.
- one branch running to the Di for aquarium usage.

I figure I will need an auto shut off valve of some sort, so the system isn't always running when no RO is in demand???

or do I just need a shut off valve on the Di output? i'm thinking this isn't correct, would it not continually have waste water produced???

please help, i'm stumped. and the research I've done has left me a bit confused on this matter.

thanks!

I feed my fridge plain tapwater. It's not a new fridge by any means but is this really a problem?

Hi:

I have an aquasafe system and I ordered another faucet that I use for drinking water (goes through a final stage carbon "polishing" filter). My aquarium water bypasses this filter stage. It is in my laundry room so not that handy always.

What type of system do you have?

Aquasafe systems has a fridge kit on their site, comes with the "T" and 30' of tubing. You should not need an ASO if you split the feed at the end (near the holding tank/faucet end). I used this kit to feed my fish tank and my holding tank, works great.

Nope, no problem. Just preference. We have a bottled water dispenser already.
Just figured I'd hook up the rodi to the new fridge. I don't like how the water is tasting out of the fridge right now.

I've got a rodi that I've been using for years, it used to be hooked up in a detached laundry room, only used for making aquarium water.

I figure since I have it, I might as well let the family drink purified water as well.

Typically just a tee and extra 1/4" tubing should be all you need. All ice-makers I've seen use compressor type fitting to connect to 1/4".

You should use a pressure storage tank though if you don't already and if you don't want to drink DI then the tank has to be installed between the ro and di as well.

Ok, so I have a pressure tank, but haven't used it before.

So I just tee the line inbetween the Ro and Di, bypassing the Di going to the pressure tank, then from there to the to the fridge.

But what about the Di output? Do I just put a shut off valve on there? And close it when I don't need water for the aquarium?

Sorry, I'm having a hard time visualizing this. Because there is always water running through the Ro, would I not have waste water continually being produced?

The pressure tank will shut the Ro off if the tank is full and there is no water demand on the system.Some newer fridges will not run on an R o system because the pressure requirement is too high,check your manual.

Thanks for the tip about the fridge.
My manual says 35-120 psi, so I should be good.
I was close to 100 on my Ro off the tap.

I know the pressure out of the tank will be lower, so I'll throw a gauge on there to doublecheck.

But I'm still lost. I have the output off the Ro tee'd. One leading to the tank and then the fridge. I get that that will shut off due to solenoid on fridge.

But what about the other leg of the tee? The leg leading to the Di? Won't my source water be flowing through there still??? Continually producing rodi and waste water until it gets shut off somehow???

You need an auto shutoff on ur or system bulk reef supply has them( if you don't already have on on it, out of ur or you will have a T that goes one to your DI and one to your fridge, on the DI your going to want to have a ball valve or some sort of shutoff. On the fridge line you will have another T one side will go to the fridge and the other to your pressure tank. You may want a check valve between your "DI" T and your pressure tank so that you don't use water from your pressure tank to feed your DI. If you don't you will not have any water in the pressure tank while making DI water. Hope this clears it up.
