1st RO/DI

[Milad]

heating the water doesnt mean using hot water. I believe hot water kills the membrane

whats your TDS out of the tap? Whats the pressure before the RO/DI unit and whats the pressure before the membrane?

if you dont have pressure thing, you can get a pressure meter from homoe depot and throw a T on it wherever you need to measure at. Should be at 80psi from tap, around 60 before membrane.


TDS is high, you have good water going into the drain and bad water coming out of the hose. So you have the waste and good water backwards
If pressure at tap is low then you need to increase it
If pressure right before the membrane is low then your carbon and sediment filters are old
