I just received my TDS meter in the mail and tested the RODI water I have had sitting in the 20 gallon Brute container for the past three days, and it is 40PPM.
My RODI unit is brand new.
My tap water is at 260 PPM.
This is very disappointing.
I will re-test newly made RODI water tomorrow. I can't believe my filter sucks that bad.
In other news, my crapclone 100 is actually doing its job.
The "crapclone" is working...so is your RO/DI unit. 40 from 260 is quite a bit of a clean up for a filter.
I was told by the Culligan man that the more you use your unit the lower the TDS will be....the pressure is higher if the unit is not used often, so when you finally do use it...particles are pushed thru the filter making the TDS number higher. If you use the water often then the pressure is reduced, and the less pressurized flow is the purest water.
I use my RO water for cooking, drinking, topping off two good sized tanks, and water changes...at last reading my TDS was 4...The reading was taken right after I had just filled my 37g WC tub. The Culligan man said he seldom finds a TDS at that low of a count, under 10 he considered it to be very good, but most folks have a TDS at 20 to 40. He then said that I must use the crap out of my unit...So very true.
So going by what the "water expert" told me.... your unit is working....try filling your tub, and take a reading from your units water, and see what the TDS number is afterwards. If it is indeed lower with use as he said...try emptying your units holding tank, and let the trickle fill a jug, and then empty it into the water changing tub. ...that's what I do so the tub has the purest water possible for water changes.
I use a rented unit from Culligan because I have super nasty well water and I was concerned I couldn't afford new filters all the time. Culligan takes care of that so I don't have to worry about it.
