Troubleshooting
Here are some solutions if you suspect your system is not providing soft water.
Basic:
❑ Verify that the by-pass valve is in the service mode (blue decal should be visible).
❑ Verify that the system is plumbed correctly (influent water pipe into the inlet
side of the by-pass valve and effluent water into the outlet side).
❑ Verify that there is salt in the brine well inside of the cabinet or inside the
separate brine drum (on systems so equipped).
❑ Verify that there is not a salt bridge that's preventing water in the brine well or drum from contacting
the salt pellets and generating brine. If there is a salt bridge, gently dislodge it by inserting a broom
handle or other dull object into the salt.
❑ Verify that you have not used rock salt as a regenerant by looking for evidence of rock salt or debris in
the system cabinet or separate brine drum (on systems so equipped). The dirt and rocks inherent in
rock salt will damage your system.
Advanced:
❑ Determine if there are any slow leaks in the house that the softener will not meter.
Repair any leaking toilets or faucets.
