My Kinetico softener runs constantly. I had it in to the shop here about 6 months ago to have the carbon replaced in it. This system has the double tanks on each side. When I got it back it seemed to recharge fine, however one side didn't seem to be doing as good a job of softening the water as the other. Now it seems to be stuck in a re-gen cycle?

I have an older Kenmore model 348491 that is not sucking brine. I have cleaned and replaced the gasket in the Venturi as well as all gaskets in the control head. I have not replaced the rotor disc. The unit pulls suction in the brine position but seems very weak. Not enough to pull liquid fully up the tube. Looking at the manual specs it shows a water flow of .6 liters per min in brine mode. Measuring the discharge hose I get about 1/3 of this. I'm guessing the low flow is not pulling enough vacuum. Should I replace the rotor or does anyone think the resin bed is plugged as a possibility? This unit is about 10yrs+ old and on City water. Looking for help. Thanks
