should be fine. give the d.i vessel a shake or roll it about the garden that will take the tds down.

9 is ok to use as long as you thoroughly rinse.

I once got water off a mate before I bought my own R.O, he rained harvested, even though he pumped it through a D.I it still came out at 15ppm.. I thoroughly rinsed then checked every job after, they all seemed fine.

I now keep mine under 4ppm so change Resin every 8/9months or so.

I remember  couple of threads that’s have  been posted before, I have spotting at 003 on my clean windows before always change mine as soon as I see 001 have shaken Di bottle daily and got another week out of it.

I would say no the whole reason we use a tds meter is to monitor resin condition once you have any reading above 000 there is likely to be issues many are prepared to use very poor quality water so will disagree with this but that’s up to them this is why so many have issues as they don’t maintained filters as they should leading to spotting issues we never get these problems and I put it down to water quality

Will use water up to 5 but no higher. Inadvertently once used some at 11 on a quarterly clean and got no complaints. Rain doesn't cause spotting so I doubt anything below 10 properly rinsed would

Cleaned my windows last week with 2 had no issue, but when it changed to 3 I chucked some over the glass, and could see from the inside it was spotting.

so change at 2 for me..

This spotting will get worse now the sun has decided to come out and start baking on the glass.

Change your resin
