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 our dependant applicances. Such as: ice-maker, fridge and humidifier.

The causes are listed from the most frequent and probable to the least likeliest.

Clogged Membrane
Bad Pump
Tank pressure too low


Use pressure gauge to monitor the tank. Ideal pressure is 5psi for the 4 gallon tank and 7psi for he 14 gallon tank


Tank bladder ruptured
Locate the pressure valve on the tank to see if water is leaking out. If water is leaking out, then the tank needs to be replaced. Furthermore, a raptured tank tends to be very heavy compared to regular full tank.
Check valve clogged

Test the filter
