Frequently Asked Questions (FAQs)

Why does my RO cabinet crack?

Cabinets may crack due to accidental impact, poor-quality plastic, prolonged UV exposure, or aging materials.

Can I repair a cracked RO cabinet?

Small cracks may be temporarily repaired, but replacing the damaged panel or the entire cabinet is usually the safest and most reliable solution.

How often should I clean my RO cabinet?

It is recommended to clean the cabinet at least once a week and inspect it monthly for signs of damage or leakage.

Which material is best for an RO cabinet?

ABS plastic is considered the best option because it is durable, lightweight, water-resistant, and has a premium finish.

Should I replace the entire cabinet if only one part is damaged?

Not always. If only the front cover, side panel, or accessories are damaged, replacing those parts may be sufficient. However, if the cabinet structure is compromised, replacing the entire cabinet is recommended.
