    I just ordered a Rodi system, and wanted to know what people used to keep their water supplies.  I was thinking rubbermade trash cans.  bad idea?
    Thanks

    I use a brute trashcan and I think that's pretty standard in the hobby.

    I use a 20 gallon storage tot, covered with a float valve in it, so I do not flood it, it is placed on a shelf about 5 feet up.
    it is also use for top of water for my tank all the time, and can drain it into my 15 gallon tank where I mix salt.

    You want a Brute not only because they are strong, but also because they won't adversely affect your water.

    Anywhere that sells farm supplys most often sell poly tanks, you can get them in many different shapes and sizes. I have 100 gal for fresh water, and a 65 for salt

    A lot of people use brute trash cans which are great, but they take up a lot of room. Another thing is food safe plastic drums. I have one of those and it takes up a lot of room, plus the lid is sealed and its a pain to get into the thing to instal float valves, or pumps, or whatever I need in there.
    I recently bought 2, 35 gallon poly tanks I am going to use. I will build a stand so I can stack them. Should work out well and save me a little bit of room also. I was going to get 65 gallon ones, but they were huge.

    Brute all the way. any big box HW store. 20, 32, 44g sizes all awesome.

    FYI I would skip the float-valve and just fill it as needed letting the system run full on when it's running and install a fitting below the rim of the container to overflow into a drain in case you forget to shut it off. If you have a float switch, as the water flow decreases to the RO membrane the TDS coming out of it will go up. When it stops, the TDS on the 'clean' side will be very high the next time you start it, because ions will migrate across the membrane, and unless you purge the RO for minute or two you'll dump high TDS water into your DI section and burn it out faster or end up with some extra TDS in your finished water.

    Brilliant ideas. I'm glad neonbender posted this b/c I too was looking at getting an Ro/di. My question is - how large a storage container would people suggest on a 60 gallon tank with about 30 gallon sump? I'm limited in storage space in our company's utility room.

    Didn't know the float valve could cause those issues. I'm notorious for leaving it run so I need some way to shut off the water flow can't really put in a drain with my setup. Maybe I'll try to rig up a solenoid that shuts off the supply side. With the float being a secondary fail safe.

    Quicky followup question. I just installed the system, it's a Typhoon III from Air Water Ice. When I do not want to make water, do I shut off the water on the source supply, or the output? As in, do I keep the Rodi system pressurized?


    Thanks,
    Michael

    Source supply is closed on mine when not using it. (You just don't want the membrane to dry out...water should stay in the canister). I turn off the source as otherwise I would be worried about the possibility of a leak. lol

    Turn off the source. While you probably have a pressurized shut off valve in that set up which will turn off when under pressure (such as when a float valve turns off the supply) there's really no reason to take that kind of chance that something will fail and cause a flood.

    Definitely on the source side. Then before you start making water again, put the output in a bucket and run it for about a minute or two to 'purge' the membrane container. I put a bunch of tees and valves in my setup so that I can divert the output from the RO directly to a bucket, then after a few minutes I shut that off and open the valve between the RO and DI so I don't hit the DI with high TDS water.

    As Bud said, it's important to flush the membrane before using it after it has sat/ They sell flush kits if you don't want to DIY it like Bud did.

    I think if you look at all the valves on the top you should open the 1 in the middle and the 1 on the right this will flush the membrane. Be sure your waste water hose is secured at end by drain or you will have a large mess real fast.
    But the idea of T and valves is good like he says.
    I have  a shut off where it comes in, I have 2 where the waste water comes out 1 to the drain and 1 for a bucket to do water changes in fresh water tank. the rodi water I can get from 3 points one to fill up my 15 gallon top off tank with a float valve at the end, one runs into my 15 gallon tank for making salt water, and the other on off valve is where I can fill buckets from when I need to.
