Review: Making water at home

The issue

I'm on a well and the water that comes out of it is HARD as in averages in the mid 300s on a water purity meter AFTER going through the water softener. It also has Hydrogen Sulfide in it from time to time. So I store up water for the animals to use during the H₂S times. I was drinking mainly bottled water but hated all the extra plastic. (See my Drinking water post about testing the various brands and types. You will probably be surprised.( I bought a ZeroWater ZD-018 ZD018, 23 Cup Water Filter Pitcher with Water Quality Meter to try and avoid that but a filter was yielding me less than 9 gallons of water. Even buying the 12 pack of filters at $118 that comes out to over a dollar a gallon plus you have the filter to dispose of. Hard to say which has waste but the filters weight about 464 grams and a gallon water bottle about 70 grams. (Not including packaging.) Of course some of the filter weight is not plastic and it is compressed where the bottles will take some effort to get to the same size package and so on. Either way neither seemed like a good choice.

My setup

What I came up with

Step 1

I had decided on distilled water for bottled water from earlier testing I started thinking why not just distill the water? After reading reviews I figured out the base models are not very good. What you need is a model you can adjust the heat on and a timer to make sure it does not run dry. Here is the water I started with. It is hard to see but this is a relative soft batch at 284.



Starting with the review and then doing a bit of experimentation it appears the the temperature dial and read outs on the distiller might be off a bit. I set the dial right at 100C but it says it is cooler.


Then I set the timer for 3 hours. (Which is a good deal shorter than the 4 to 5 hours in reviews and still distilled almost all the water.) That gives me water purer then most of the bottled waters on the market.



This is what is left behind. I poured some of the less than 1/2 inch left in the boiling chamber into a beaker for this pic. That is 8260 on the meter! I did not notice till I was posting this the 10x indicator in the low left of the LED readout. Kind of shows why you do not wan this to boil dry withe a 320 degree auto shutoff like the base models do. Way too much of this ends up in your output.


Estimates were around 50 cents of electricity per gallon in review so it could be way cheaper too. I appear to be running it cooler and shorter than most so maybe even better.

Step 2 (optional)

You probably want something to hold s the water and possibly filter it. Which lead me to getting the ZeroWater (ZBD-040-1) 40 Cup. From the reviews the valve on this is junk so you will want an after market spigot too. This give me a 2+ gallon buffer ready to use water as pure as the distilled bottled water (zero on the meter) and the filters should last a long time since the water going in is pretty pure to start with I'm keeping tabs on how many gallons I get from a filter so we'll see if it is all worth it. More to come.
