BWT softener installed but water remains untreated because the unit is in permanent bypass

Safety first: Confirm which valves control the softener before adjusting. Sudden changes can affect water supply.

• Identify positions: Refer to the BWT connection block diagram to identify Service, Bypass, and Closed positions.
• Set to service: Move the bypass lever or valves to the Service position so water flows through the softener.
• Check for stiffness: If the lever is hard to move, gently work it back and forth. Do not force; internal damage may occur.
• Test water: After a few minutes, test water hardness at a tap to confirm softening.

If the bypass valve will not move or leaks in service position, it may need replacement.
