RODI System issue

[Dexter922]

Sorry for being needy lately. lol.

I purchesed this rod system used and knew it needed filters changed. So I changed all filters, including the membrane.

For the first 50gallons, I get 0 readings. But then after that, it spikes up and it’s almost as if filters are spent and I’m reading north of 25. So I thought in line meter was busted, so I got a handheld and still get the same readings.

Something has to be off, I’m just not sure what. I literally just changed them all. Any ideas? I can take photos and post them later.

Did you disconnect the line after the carbon block and flush it first?

Yes about 5 gallons worth

New resin too? I usually flush the carbon, rehookup the line. Unhook line after membrane, flush again. Then rehookup line. If changing the membrane when changing carbon block.

Here’s a link in case something was missed.

How to Change Your RO Membrane

The membrane is the heart of your reverse osmosis systems and is where a majority of the contaminants are rejected from the water. Based on the frequency of flushing, how much water you produce, and the quality of that source water, you will need to change your RO membrane every 3 - 5 years.
