just check my water butt for ppm have about 100 litres of water remaining been in there for about a week just check my ppm 00.1 would that be OK to use still? have my first jobs on Tuesday and don't want to mess up.
Truely understand that , i was very strict on my water at first , and i change my resin when it climbs up , but i dont measure it Daily anymore . Maybe 1 a week . Im RO at first Down to 15 and DI the rest Down to 0 of course . But im confident that anything under 8 is not visible to the human eye. And im sure you could go even higher... Dont wanna try though
