We have a GE Smartwater Reverse Osmosis System ( Model # GXRV10ABL01). We have an under sink unit with the storage tank...it is hooked up to the the normal dispenser that goes on the sink and we also have a link to the icemaker. We started noticing that the water pressure was getting low out of the RO water dispenser and the ice cubes were coming out hollow. We changed all the filters and it seemed to work real well for a few days. We are now back to very low pressure and hollow icecubes. We checked the H2O in supply line and there are no problems there. We pulled each of the connections off and cleaned the lines. No visible problems there. The supply tank doesn't seem to be filling all the way either.
Thanks for any suggestions!
