Why Does the Water From My RO System Seems Cloudy?
The water out of my RO system seems milky or cloudy, what is the reason for this issue?
This is generally caused by trapped air within the RO system. However, it will not affect the quality of your water. The cloudiness should disappear within a minute after water sits in a glass. This is a normal occurrence with a newly installed RO System or after a filter change. You can release the air from your RO system by draining the tank 1 to 2 more times or using RO makes humming noise air release instructions in your system manual (see below).
Instructions to Release Air Trapped in Check Valve:
- If your RO system makes a whining or humming noise, most likely it’s due to air which got trapped in the “Check Valve” during installation. So we need to get rid of the air in the Check Valve.
- The Check valve is on the left side of the Membrane Housing (see Fig. Step2). It is an internal valve encased in the L-shaped plastic fitting. It connects to the Clear line that puts out pure water from the Membrane housing.
To relief the air bubbles, do as follows: (See Pictures Below)
- Step 1: Close the Tank’s valve.
- Step 2: Tilt the RO system to the right. Put something under the 3rd filter housing to keep RO tilted. This will help dislodge the air bubbles from the Check Valve.
- Step 3: Turn on the RO spigot. Let pure water flow thru spigot for about 1 minute. This forces the air to flow directly out to the spigot, bypassing the tank.
- Step 4: Turn off the spigot. Wait for about 10 seconds. Repeat step 3 again. Perform this step around 3- 4 times.
