PING:Marc or other RO\DI experts

[Billy]

Ok, i've just installed my first RO\DI unit, after some issues with
leaks at the water source, it's working. I'm running it through it's
first few gallons of water, as directed. I have a couple questions.

1: I understand that there are 4 types of steps. Particulate, carbon,
RO and DI. The unit I have has 5 'sumps', what is the fifth a repeat
of?

2: I want to place a water time on the water source so it doesn't
overflow if I forget about it. Is it ok to have the source water shut
off?

3: With the water in the unit go 'stale' or 'stagnant' if I don't
make any water for an extended period of time?

4: How do I change cartridges without dumping several gallons of
water on the floor? I don't see how to 'drain' the unit.

Stage:
1 - sediment filter
2 - carbon filter
3 - membrane
optional:
4 - post carbon
5 - ION

Your fifth or last stage [RODI unit] will be DeIonization stage / filter.

You can try using a float to cut off water from your preset level.

When using food grade container and tighten of it top, it should be ok for
about a week as long it not expose to the sun. Or you can try making another
batch if you think or taste funny.

Your RO or RODI unit should have a waste line that dump into your drain.
If you talking about taking apart of your RO unit, you can try changing it
with a large bucket or similar. I assumed you turn off your water source
that coming in to your RO unit.

Well, apparently I didn't phrase those very well, you missed my
meaning on all 4 questions.

Than, can you rephrase your meaning and see if I miss again. Maybe I just
did not have enough java intake this morning or the caffeine did not travel
fast enough to my head.

Aye, Sure can. Marc is at Macna, forgot.

1: I understand that there are 4 stages. Sediment, carbon,
RO membrane and DI. The unit I have has 5 'sumps', which stage is
most likely to have been repeated?


2: I want to place a water time on the water source so it doesn't
overflow if I forget about it. Is it ok to have the *source water*
shut
off? I do not want to get involved with float valves in the
destination vessel and such.

3: With the water *inside the unit* go 'stale' or 'stagnant' if I
don't
make any water for an extended period of time? Will the cartriges be
"fouled" if it's left idle for a long period of time filled with
water?

4: How do I change cartridges without dumping several gallons of
water on the floor? I don't see how to 'drain' the unit. eg: removal
of the acrylic 'sumps'
will result in a large amount of water on my floor.

Most common 5 stages unit will repeat in carbon.
Like the following:
1 Sediment
2 Carbon
3 Carbon
4 Membrane
5 DI

Is this what you after? Or am I still missing the point?
Or....
If you purchase a whole unit, it may have label on each unit of what it is.
And OR....
You can verify yourself from opening the unit and see which are the same and
which is not. Then you know what unit are repeated.

Again, my answer is using a float. There no timer that I awhere of. A float
will close as the preset level is reach.
Or.
If you have a RO unit wiith a pressurize resurvior tank, you can use an
AutoShut-offVale.

My answer is the same from the first reply.
As long your water is not expose to air or direct sun light, it can store
for weeks with close tight led.
It vary depending on how you storage your water and it environment condition
is placed.

My answer is the same from the first reply.
Use a large bucket or container to change your unit cartridge / media. Close
all incoming source. Place unit in bucket and use a RO wrench or use your
hand and twist the unit cover off.

Usually a carbon repeat.

Perfectly ok.

Well, I'm no biologist, but mine stays off for extended periods. I make
water about every 6-7 days, sometimes longer, and it hasn't caused a
problem.

Cant help you there, mine's not permanently mounted. I move it to the
kitchen sink for maintenance.

Hi Billy,

1) Your first filter is your 5 micron Sediment filter. It
should be white at first, and later turns orange as it traps
larger crud.

The second and third filters are carbon block.

The white tylenol capsule on top of your unit is the RO
membrane.

The final stage is your DI. A color-changing one is ideal,
but if you have a TDS meter, you'll know when it is exhausted.

2) A water timer is fine. I use a digital timer that I
bought at Linen's & Things for $10. It times up to 99
minutes. 60 mins makes 5g in the summer, 85 minutes makes
the same in the winter. Another method is to set the
"alarm" in your cellphone to ring/beep when the duration has
elapsed. It is easy to clip to your belt and a great reminder.

3) It is best to run your unit once a week even if just for
a few minutes. If you are making drinking water as well,
you'll turn it on often enough. Leaving it off for weeks or
even a month would be questionable.

4) Turn off your source water. Open the valve to release
the pressure in the unit. Now you can carefully unscrew the
cartridges without dripping any water at all. I put a towel
underneath the unit just in case, but it won't make a mess.

Rinse the sumps out carefully, and be sure you put the
O-ring in place before screwing them back on. After you
install new filters, always run about 2g of water and toss
it, to avoid adding any impurities into your system.
