Water Deionization at home/workshop

[JOGARA]

Went for this system, Finerfilters 4 Stage Compact Reverse Osmosis Filter With DI Resin (100 GPH)

It is only £57 and should last a decent amount of time.


Don't have water into the workshop yet so just shoved it on a stick by the outside tap..



Within a few hours (4-5) I had 20L made.



Using this TDS meters, Yakamoz LCD Digital TDS-3 Meter Temp PPM Tester Pen
Found that our tap water is between 120-160 (taken at multiple times of the day, is that a thing?)
The filtered water, 000 :)





With the 20L I have made, waste water is nearly 200L.
This will be used elsewhere but is a lot more than what others are saying being 1:3-1:5 ratios.
Apparently you can/should clamp the waste to get better ratio?

Either way. Cheaper per liter still.
SevenTrent are charging us "£2.41" per 1000L of water. I was paying £2.29 at ECP so even with the 20-30L I had to flush through the system to prep it I am less than a quarter the price already (excluding the system setup and running costs).

10/10 Would recommend.
