Current tap water TDS readings of BC

my filters have to be replaced monthly it seems. I have had the ro/di unit for 4 months, going to buy a new set (my fourth) very soon, as my PSI in the unit is down to 20...

usually it runs at 45 or higher.

Just installed my first ro/di unit (Reefmaster from the US). 5-stage. Seems to be working well -- although I wasn't aware that ro/di systems employ runoff (roughly 3 to 1 ratio of waste water to filtered water!). Seems like a terrible waste of water!

Anyway, my new (calibrated) TDS meter is reading 12ppm in James Bay, Victoria.

Does this sound about right? Relatively speaking, is this clean or dirty?

The waste water is a negative enough that people talk about capturing it to wash clothes, water the grass etc but I can't see going through the effort, guess I'm not green.

The output should be near zero or at least low single digits (mine was 2 last checked) once everything flushed.
