Want to make a RO/DI storage container

[cham]

Hey Guys,
I want to make a RO/DI storage container using the 44g gray brute trash can and lid and some type of float and valve to keep it automatically filled at all times. Just so I can always have a good quantity of fresh water available to me and not keep having to "brew" water all the time. I seem to have a knack for forgetting and get an overflowing mess in my garage.


1. I've heard RO/DI water aggressively pulls minerals from every thing so make sure it has a good lid. Do you think the brute can and lid will work? I anticipate using 100 to 120 gallons per month so it should have the water replaced 2 or 3 times per month

2. What gadgets do I need to buy from you guys to accoplish auto top off of my storage?


Thanks! :)

That 44 g brute ought to work just fine. You can make this sort of set up as complicated as you'd like, but being a fan of simple, I'd go for drilling a hole through the side and inserting a float valve. The floats we stock have a built in bulkhead fitting that has a easy compression nut on the outside you can hand tighten after inserting the 1/4" tubing.

As a failsafe you might want to install an overflow pipe.

As long as your RODI system has an automatic shutoff valve - you should be good to go.

Hey Russ,

I am a huge fan of simple too. Sounds like we are on the same page.

I only have a standard 4 stage RO/DI and use a manual ball valve for on/off operation.


Do you have a list of part numbers I would need to make this work? Should only need a float valve and shut off valve right? I am not familiar with the automatic shut off, is it pretty straight forward?

[BuckeyeFS]

BFS-174 Float valve, adjustable - 1/4 inch tube - $14.90
BFS-117 Automatic shutoff valve - $9.75
BFS-112 Quick connect check valve - $6.50

You also may want to get 2 or 3 feet of tubings to help with the set up.

You can email us at Sales@BuckeyeFieldSupply.com and we can send you instructions ahead of time. Its not hard at all.

Great

No problem at all Russ. I am still waiting on the parts so I was just getting a jump start on things.

Thanks again

Happy reading - let me know if you have questions.

Comes to a question. If you use the float valve to fill up the reserve tank, this will create a short cycles on/off.
Will it also create TDS creep?

[BuckeyeFS]

Ideally, you'd have a reserve tank that either has a long-throw ATO device, or is manually filled periodically so that you don't have frequent cycling.

TDS creep occurs when an RO system kicks on, so the answer to your question is yes.

[shikhyung]

You say yes, but seems that is nothing to worry about....
The reason that I ask because that is what I heard, and because I really don't understand much about how system work...

[BuckeyeFS]

The key to dealing with tds creep (the relatively high tds water you get from an RO or RODI system upon start-up) is that you configure your system so that it doesn't cycle on and off frequently.

This is one of the reasons for instance that we don't recommend that folks plumb their systems directly to a float valve in a sump. If they do that the system will cycle too often.

A reasonable goal is to try to have the system cycle no more than about once a day.
