Just switched my system on to fill my IBC and last week and this week i have noticed a small rise in the TDS out from the ro.
it was the same last summer i have bad pressure problems and water flow so my tds was quite high in the summer, then over the winter it came down to around 7/8 ppm lower. Now ive noticed a rise of around 3/4 ppm.
Is this normal for when the weather warms up a little? i carnt remember if i seen someone write it goes a little higher in winter or summer.
