The causes to the output problem are listed in the timeframe that you've owned your RO system. The grey background applies to systems in use for under 3 months and the white background applies to systems in use for more than 3 months.
When trying to identify the causes of slow and little output. Isolate the RO system by shutting off your dependant applicances. Such as: ice-maker, fridge and humidifier.
The causes are listed from the most frequent and probable to the least likeliest.

Defective Pump (Extremely Rare) |
Pump is not operating at full capacity: 20psi input should translate to about 62psi 30psi input should translate to about 67psi 40psi input should transate to about 70psi Add a pressure gauge after P2 and stage 2 filter. See if the pressure increase is apparent |

|
Defective Membrane Housing (Extremely Rare) |
Waste water flows non stop down the drain line and no RO water.

|
Tank bladder ruptured
