    Default Autotrol 255/440i water low flow and brine tank backing up

    Hi There,
    I'm trying to figure out what's going on with my water softener. I do not know the age of the system. The problem started with a drop in water pressure to the house, bypassing the softener fixed the problem. In addition to this, when I do run the softener the brine tank backs up. At the beginning of the slow rinse/brine cycle, brine is initially drawn into the air check valve and then slowly you can see the direction of the water reverse.

    I have taken apart the control unit and the following has been checked:

    -Injector/screen are clean
    -everything has been rinsed for a blockage
    -brine line should be clear as it initially draws brine and backs up water just fine.
    -drain line gets good flow.
    -flapper valves look ok. One of the larger ones was a little bit rougher, but not too bad.
    -The air check valve fills with water fine. there is a bubble in there throughout the cycle.

    Any thoughts, ideas? Could the resin be the issue?

    Cheers,
    Matt

    Very likely the resin is fouled or has failed.

    If you have iron in your water iron fouling is very possible--particlarly becuase the regeneration is apparently not working. The fact that brine tank fills indicated that there is a problem internal to the control head--possible bad flappers. A rebuild is indicated.

    If you are on a chlorined municipal supply chlorine may have degraded the resin. Check by taking a sample of the resin and press between your fingers. If it is mushy it has degraded. If the resin beads are hard they are probably ok.

    Most likely you have compacted resin in your mineral tank. Bypass immediately so you don't have resin break through. This is a fairly easy repair if you are somewhat mechanically inclined. If you need more assistance please let me know.

    Hello again, so flapper valves aren't the issue.

    Jim can you give me a few steps to see if the resin is compacted?

    Thanks.
