RO/DI Question

[Ryan22]

Last night I desided to change the filters in my RO/DI unit, and when I fired it back up, the last filter chamber didn't fill up with water. The prefilter and the carbon chamber filled up, but the last one didn't. It's producing water, but it's reading right about 100 ppm on my tds meter. Any thoughts on what I did wrong?

TIA,

hi.
You can try to bleed the air out by inverting the unit, and the high reading may go away if you let it run for awhile.

I put my filter in upside down once and that happened to me.

Check that too.
