I bought a used kent 4 stage ro
setup... Ive done alot of work to it after i got it.. (i should have just bought a brand new one, cost about the same.) The pre-filter and carbon block had been changed before i bought it and i just changed out the DI
resin tonight.. Ive replace all fittings/hoses.. added pressure gauge and flush kit.
It came with a dual line TDS
meter.. The unit was plumbed wrong when i got it, not sure if they ran it that way or not.. They had the water going thru the di
resin first then to ro
membrane then out of unit. I changed it back to the way it is suppose to be..
I am taking readings after the RO
output and after the DI
out put. After RO
im getting 0-1 ppm tds
.. After di
resin 0 Tds
.. I thought maybe the tds
meter was bad, so i switched one of the probes to test incoming water supply it and it read 115-116 PPM TDS
. SO , i assume the meter is ok..
So , my main question is ..IS it possible to have such a low TDS
reading just after the RO
membrane.. I'm guessing it is because my incoming water supply is only 115 or so and water pressure is 65-70 PSI.. Any help would be cool .. thanks
OH,, im filling my 65 gallon tank right now for the first time (started this project in july..lol) i just want to make sure my water is good!!
