🚱 1. RO Water Purifier Not Dispensing Water

Problem:
If your RO purifier is not dispensing water, the most likely causes are:

Clogged filters
Faulty RO membrane
Low water pressure
Malfunctioning storage tank

How to Fix:

Check and replace clogged filters
Inspect the RO membrane and replace if needed
Ensure sufficient water pressure (at least 40-60 PSI)
If the storage tank bladder is faulty, it might need repair or replacement

💧 2. Slow Water Flow from RO Purifier

Problem:
A noticeable decrease in water flow indicates:

Clogged pre-filters or membrane
Low air pressure in the storage tank
Sediment build-up

How to Fix:

Replace pre-filters every 6 months
Check RO membrane if it’s older than 1–1.5 years
Ensure tank air pressure is around 6–8 psi when empty

Tip: Regular maintenance avoids slow water output issues.

😣 3. Bad Taste or Odor in RO Water

Problem:
If your purified water has an unpleasant taste or odor, the causes could be:

Worn-out carbon filters
Biofilm growth inside filters
Expired post-carbon filter

How to Fix:

Replace the carbon filters promptly
Sanitize the entire RO system once a year
Always install a new post-carbon filter with the membrane change

How to Fix:

Check the automatic shut-off valve (ASO) and replace if defective
Inspect for any leakage
Replace the flow restrictor if water is draining continuously

Leaks from the purifier are usually due to:

Loose fittings or connectors
