Been using coway so far stratified with their service. but last Friday did a PH test on the water found out the drinking water from the machines is acidic (around 2). water from tap is PH 6-7. Not sure what is the problem, saturday talked to a coway people suggest me to file a report to coway. Tomorrow go back will do a final test will see how is the result.

QUOTE(pakmulau @ Oct 31 2016, 10:21 AM) Normally RO water when exposed to air it will have pH around 5-6. but this pH is very stranged. your pH meter okay? you got reference standard or solution to test your pH meter? already do 3 test with 2 different PH kit. the result is acidic. later afternoon will go buy another ph test kit to test. even the waste waster from the machine is neutral around 6-7 lah.... not sure they fix the wrong pipe or not when service

QUOTE(whilly @ Oct 31 2016, 10:26 AM) pH = 2 ? Not sure if you are trolling or failed your chemistry back in school. i'm not stupid lah.... i'm serious here, the result is orange red.... that is why i'm surprise not sure where is the problem. water from the tap is light green did a few test with different PH kit is result is the same. pls don't disturb me if u are looking for trouble This post has been edited by myasiahobby: Oct 31 2016, 10:37 AM
