Softener frequently overflows the drain or backs up at the drain connection.

Safety first: Avoid contact with wastewater. Wear gloves and eye protection.

• Check drain connection: Ensure the AquaSoft drain line discharges into an approved air gap fitting and standpipe of adequate size (typically 1-1/2" or larger).
• Shorten or reroute drain line: Keep the drain line as short and straight as possible, with minimal elevation above the softener.
• Clear building drain: If the standpipe or floor drain backs up, have a plumber clear the building drain.
• Install proper air gap: If the drain line is submerged or sealed, install a proper air gap to prevent siphoning and backflow.
