Softener causes air spurting from taps after regeneration.

Safety: Air in lines can cause sputtering; open taps slowly to avoid splashing.

• Check brine line: Ensure all brine line connections are airtight and the brine pickup is fully submerged during draw.
• Inspect drain connection: Confirm the drain line has an air gap and is not allowing back-siphoning of air into the valve.
• Proper startup: After installation or service, follow Hansgrohe's startup procedure to purge air from the resin tank and plumbing.
• Monitor regeneration: Observe a regeneration cycle to see if air is being drawn at any stage; correct the source accordingly.
