I checked the way the water flows through the system. The old company was running all carbon without a sediment filter! My filter company said that they should have been running a sediment in front of the carbon block which is before the membrane. To make matters even worse , my system runs only 1 stage before dumping into an in line carbon then the membrane. That does not seem right. Then they run water from the tank into a carbon block which really should be the inline for a final polishing.
Not sure what is going on but my Ph is still very high & my TDS is 59! Before I did the filter change my TDS was 23! I am going to call the filter company in the morning to see if they can figure out what is going on. If I am not happy with the phone call I am just going to install a 3 stage pre filtration system in front of the whole thing with a catalytic carbon stage + carbon block with sediment, if it turns out to be rigged wrong. This way I will have a sediment + carbon block in front of the membrane.
