Where to get distilled water?

[mordrake]

Yup, that's the one I've bought. Choose this one because of it's simplicity. The design can be improved further but I guess it's adequate in itself. What grade is the resin you are using?

bought the colour changing resin cartridge from Reborn (advertised by PJM in SRC n AF). once the resin lifespan expire, i'll replace the resin with the one i got from Tigger. the cartridge is reusable... that's why i bought it

works well so far... TDS from tap 52 down to zero.

).

that is a good idea!
guess we could improve by joining another 2 equal lenght pipes by fixing 2 U-joints to triple the effective flow length

or make it more compact by using 3 shorter length pipes connected by U-joints. Good idea?

possibilities are endless but must take into consideration where you are going to mount the unit.
my wife will roast me if she sees some multi-pipe contraption in the toilet

I don't forsee a need to mount it for my use. I just lay it on the floor when I need the DI water. And after use, I just leave it standing somewhere where the water will drain out. When it's stopped dripping, can place it somewhere else.

hpeter, if I were to make further modification, I'll get another shorter length of pipe to house the carbon medium separately. I was told that the tap water feed to this diy DI setup has to be as slow as possible to let the carbon absorb as much impurities as possible before it reaches the resin.

yes, even for those 3 stage filters, flow have to be real slow. took me more than 30 mins to fill a 20L pail. at fast rates will not be as efficient and the pressure builtup might be too great... water hose pop out.

all the more important to increase the length for max exposure time.
My suggestion of multiple bends would increase effective length with compactness but was thinking with too many bends may hv difficulties in emptying and refill contents inside?

[BFG]

My guess is with the extra length meant extra resin being used translating in a higher cost as more resin is applied. If yours is for a pico tank, no need to use more than needed. And from reading at ReefCentral, DI water need to be stored properly or else it will be contaminated. To maximise the removal of impurities, my idea is to use more carbon, cheaper than the resin. You may want to increase it's usage volume so that it will maximise the resin lifespan.

pico tank... just buy the distilled water off the shelf

a DI unit would make most economic sense for bigger tanks.

have said that already in previous post in this thread

I've found that with the total cost of the tap water filters/RO units + the cost for the media (whatever it is) that it is much cheaper for me to buy Reverse Osmosis water from a local walmart. I pay $0.33/gallon and i'm convinced that it is better than if i would try to filter it myself

Guys, what's the water bill like here in s'pore? $1 per 1000liters?

looks confusing... think our waterbill has the rates
