Post by: A & J Owen Window Cleaning on June 04, 2012, 01:24:05 pm
someone said on here ages ago about the filtering process i have a 16 ltr and a 25 ltr vessells hooked up so when the water starts to creep up i change the connectors to use the other vessell as a polisher. but this is not happening any info on this

have you just swapped the over, or changed the resin in one of them.

the second DI has to have brand new resin in to work, and get the ppm to 000

i would use just 1 at the moment until the tds rises, or use them parallel with a splitter

So you use 1 DI, untill it rises to roughly 010

Then swap, and use another DI with new resin, untill that reaches roughly 010. Then once this happens, run the 2 DI'S together and it will come out at 000 again. Is this correct?

yes, use 1 DI until the tds rises then you can connect the second in line
