Some say under 10.
I say 0, as if you have a value you will never know what is getting through, it could be the dreaded PO4.
So how do you guys test your Ro water and with what thingie, maybe this is where my problem lies....
My RO Unit drips a few drops a second of good water. Is this normal and how can you increase it?
I have the RO + one. There is a resin compartment but there is nothing in there yet.
So basically you have to leave the tap on the whole day to get a few litres of water?
