I’ve just replaced pre filters and ro with hf5 running 55 psi how long should I do a flush for first and then what should I expect the readings to be after ro? Thanks
-
Anything in single figures (ppm) is good.
What's your tap tds?
-
Tap TDS is 290 ish I do have a v11 controller and booster pump coming so that will push it up to 80 psi the recommended for the hf5 so will low pressure keep the readings a little higher for now as the ro isn’t running at its best? Thanks
-
Yeah i reckon if you get your pressure up to 80 psi you should be looking at an output Tds of below 9ppm.

One of the suppliers says around 2 hours.
It could take a while thereafter to settle down, maybe a couple of production days. However, mine had limited flushing and stared producing water from day 1 at 98% rejection rate.

I flushed it for about an hour and it went to 19 it’s now filling the van so I popped out and took another reading and it’s 16 so maybe after a few production days it will get lower.
