[Pristine Clean]

my TDS reading flactuates at the moment! Which I find strange.

I have a 5 stage RO unit. I have

40/40 ro
sediment
carbon
DI
Water softener

readings taken this morning are 003at around 6.45am    -     007 at 7.15am   -      005 at 7.50

The fist time I had 1000 litres pass throu I was getting 000

Advice appreciated.

Dave

How are you taking the reading? Are you making sure that the container you use is clean? Even a tiny amount of contaminant left in the container can give a higher-than-normal reading.

Try rinsing the container (I use a small plastic beaker) a few times before taking a reading. You should find it's pretty consistent.
