Maintenance Tips
- If you notice backflow or draining, inspect the flapper and sealing surfaces for debris or scale buildup.
- Use the clear lid to visually confirm the check mechanism moves freely during operation.
- When servicing, replace worn seals/O-rings instead of overtightening the lid.
- Keep water chemistry balanced to reduce calcium scale that can prevent a positive seal.
