BWT Perla Maintenance guides

Delayed maintenance can affect not only flow but also hygiene and treatment performance.

What should be checked?

• Keep a record of pre-filter and membrane replacement history.
• Watch for reduced tap flow, taste/odour changes or unusual pump noise.
• Check filter housings, connections and tubing for leaks.
• For tank systems, follow manufacturer instructions for tank pressure and sanitisation.
• Apply sanitisation steps when recommissioning after long periods of non-use.
• Assess filter life using water quality and consumption, not just the calendar.
