Water Ionizer Schematics Request

Jim wrote me recently:

Hey Mark,

Do you have any water ionizer schematics? I'd like to build my own if possible, as the water ionizers I've seen for sale cost over a thousand dollars.

I know some electronics so I'd like to take the water ionizer schematics and go the " do it yourself water ionizer " path. I've seen some of the youtube DIY water ionizer videos too - and I wonder what you think of those approaches? Any good?

Thanks Much,

Jim. M.


Hey Jim,

I'm assuming you want a way to build your own ionizer, yes? But I can't imagine you want to go to Radio Shack and buy all the parts you need. Do you?. You could also buy a car battery and pull it apart for the plates you'll need. OK, I'm just kididng about teh car battery - don't try it at home please....

While I have several water ionizer schematics much of that material is proprietary, and has non-disclosure stuff (even though it's all pretty much the same) so below I'll skip giving my lawyer any money and move on to your second question about DIY water ionizer approaches. Further down I test my memory on the one I built in my teens.

Pro's and Cons of DIY Water Ionizers


1 - Inexpensive

2 - Can use filtered or bottled water

3 - Works to create alkaline pH (but not much ORP value)


1 - Takes some know how

2 - Can leach some of the plastics if charged too long

3 - Takes hours (and more electricity cost) to charge the water

4 - I'm just too lazy and want ionized water when I want it

DIY Water Ionizer Schematics

Ok, it's not really a schematic so much as instructions if I can remember what I did. You'll get some pH change but the range and ORP values will not be close to the water ionizer machines on the market which use several plates and only take a few seconds to work. Plus process will take several hours and you might want to use a timer and buy a pH test kit.

I built myself a water ionizer, and if you have about $120 you can put enough parts together to build one as well. I don't use it anymore - I use a water ionizer machine for better results - and I'll give my pros and cons about this later on.

Here's your parts List:

PVC pipe - 3 inches long and about 4 inches in diameter

Plastic storage containers

Two titanium electrodes or platinum coated plates

Some copper Electrical wire

A few electric clips - called crocodile clips

An 18-24V power adapter

A razor sharp knife

About 2-3 hours or so of labor.

Consider a pH test kit and a timer for the power supply

1) Cut holes for the PVC pipe to go from one tank to the other about 3/4 the way up the tanks. Make sure the holes align.

2) Connect the titanium electrodes or plates to the electrical wires. Then connect the wires to the clips. Then the other end of the clips to the power adapter.

3) Put the electrodes or plate down into the plastic containers. (don't plug it on yet)

4) Fill the jugs up to where the water passes from one jug to the other.


- To avoid shocks keep the electrical wires out of the water (just the plates or electrodes go in the water).

- Do not drink any water that gets discolored.

- Make sure the water is clean mineral water. Distilled water and RO water lacks the minerals to be ionized.
