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.
