New RO/DI unit Install Help

So the Typhoon III has been in my basement for over a month now. I want to tackle this soon but still am confused.

I solved the problem of 1/4" to 3/8' lines by getting the reducers so I am past that. Here is my final dilema -

My current unit has an input, a drain, an output to a 2 gallon container, and another output to the fridge and faucet. Must have an internal ASOV or something. Sends water to the container then when full, pulls from the container to the house, then refills.

The Typhoon III has an input, a drain, an output for RO and an output for DI.
I plan to send the RO to the line that goes to the house and the DI output to the tank.

QUESTION / PROBLEM.
With this I cannot figure out how to have a container? Can I T this DI out put with a valve of sorts to drain into a large container to collect for water changes ? Going from 1 GPD to 175, maybe I don't need the container reserve, but I would like to fill a container for changes.

Any Plumbers out there?

Cheers

 

Is the 2 gallon container now completely sealed? With a fitting that looks like an air fitting on it?

If it isn't, can you post a picture of your current setup?
If it is:

The RO water outlet should go to a T. One side of the T goes to the 2 gallon container, the other goes into the house. There should be a shutoff before the T so that you can turn off the "house water" to make DI water. The setup I have had the shutoff on the tank. You just have to kill the pressure from the tank before you make DI water.
The outlet from the DI cartridge goes to your water storage container.

The sealed storage container. The way it works is you have a T from the RO. One side goes to the faucet, the other side to the sealed tank. The tank is pressurized (usually around 5-7psi). When the faucet is turned off, the unit will fill up the storage container until the pressure in the tank is equal to that in the outlet line from the RO. When the tank/lines are all at the same pressure, it stops making water. Then when you open the faucet, the pressure in the tank "forces" the water out of the faucet until it loses its pressure or you have enough water and you shut off the faucet. It then re-fills the tank to pressure again.

If you leave the shut off to the tank open, and try to produce DI water, the pressure in the tank will force the water back through the lines, through the DI and make DI water. It puts too much pressure on the DI but it also lets all the pressure out of the tank since there is no back pressure on it anymore. Then the faucet side doesn't work properly.

If your 2 gallon container is different, please post pics of your setup?

OK,
Here are some photos of the old unit.

RO UNIT -

The first tube is the intake from the water line.
Tube in the middle goes to the house
Third tube goes to the tank
THe other is the drain.

There must be some sort of internal ASOV to switch between filling te resevoir and sending to the house or something.



NEW UNIT - Only has Intake, Drain, RO out, DI out.

 

I'm not sure exactly what you mean by the new unit has an RO out and a DI out as well as a drain. Most units have the RO waste line that goes to the drain and then the pure water output from the DI. The good water output from the RO goes into the DI canister.

Regardless, you could put a T whereever you want with ball valves on both outputs from the T.

What I mean is that there is an output for RO and another for RO/DI.
The RO will go to the hous and the RO/DI will go to the tank.

I picked up a couple of valves and t's today. May just install without storage container.
I am thinking a T for under the tank, one for the ATO and one for filling buckets for changes. I will leave the valve at the end for turning ON/OFF.

Off the RO unit, put a T. One side to the shut off valve on your holding tank. The other side of the T goes to your faucet. The DI line will go to your RO/DI water container. The waste line goes into the drain. Whenever you aren't making DI water, open the valve on the 2G container. When you want to make DI water, close the valve on the tank.
