No Water at Dispensing Faucet

–    Water supply is off —> Turn on the water supply, or open Needle Valve ( turn needle handle
counter colockwise)

–    Tank’s valve is closed —> Turn tank valve to an “Open” position

–    Output line is crimped —> Remove crimp

–    Incorrect installation —> See Fig.11. Verify all line connections.
–    Tank defective, no pre-charge pressure —> Set tank pre-charge to 5-7 psi.
–    ASO connection Error —> See Fig. 16A and Fig. 16B to reconnect ASO to the correct connection.

The ASO valve has 4 lines connected to it, 2 Reds and 2 Clears. C1 is labeled IN and C2 is labeled OUT on the valve. C3 and C4 are connected to the ends with the 4 screws. Please confirm connections:
•  Stage 3 Carbon:        Red tubing (point B) is connected to C1 (IN) fig.16A
•  Membrane:        Red tubing (point D) is connected to C2 (OUT) fig.16A
•  Check Valve:        Clear tubing (point E) is connected to C3 fig.16B
•  5th stage Tee inlet:    Clear tubing (point F) is connected to C4 fig.16B

Bad Taste To RO-CTOP Pure Water

If you are experiencing a bad taste in the Pure Water, the RO Membrane or Stage 2 or 4 Carbon filter may be depleted and needs to be replaced. Please follow the steps below to determine if the membrane or stages 2 and 4 carbon filters needs to be replaced.

  • Fill up a clean cup of water from the RO Unit.
  • Take a Pure Water TDS reading with the supplied TDS Digital Meter that came with the RO unit. Read more

What to Do When Drain Water Runs All the Time

Our RO systems are designed to shut off automatically when the tank is full. When the RO fails to shut off after tank is full, drain water will continue to run, possibly depleting the pre-filters, the membrane, and costing high water bills.

If the drain water is running non stop, the input water pressure may be too low (below 40psi). Not enough pressure to shut off the RO at all,  check input water pressure. If pressure is below 40psi, you may need to switch to Booster-Pumped RO model. Read more

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). Read more

Common Causes to Premature Membrane Failure:

There are 4 common causes that lead to premature membrane failure:

  1. Failing to replace the 3 pre-filters as frequently as needed:
    • If you’re on city water:  The over-depleted carbon pre-filters allow the chlorine to get through and damage the membrane.
    • If you’re on private well water:  The overloaded pre-filters allow excessive sediments and particles to get through and clog up the membrane surface. Read more

What to Do When Leaking From Ultra Violet Light Occurs

If you notice a leak at the electrical wires of the UV light after installing your RO unit, the internal glass sleeve inside the UV housing may have been damaged during shipping.

Please follow the steps below to determine if the internal glass sleeve is damaged.

  • Shut off the feed water line to the RO unit.
  • Shut off the tank ball valve by turning the blue cap on the tank ball valve 90 degrees. This step is not required for the Countertop Models. Read more

TDS Reading Is Higher Than Normal

If the Pure water TDS is higher than normal after 1-2 full tank flushes, please review the possible reasons below.

  • Membrane was not inserted > Put membrane into housing.
  • Membrane is inserted incorrectly > Re-insert membrane correctly. Refer to Manual.
  • Tap water source water has very high TDS and/or contains certain heavy dissolved elements resulting in TDS higher than usual. Read more

RO Storage Tank Takes A Long Time To Fill

If the RO unit takes a long time to fill the storage tank, please review the possible factors below.

  • Insufficient water pressure (below 40 psi for non-pump systems) > Increase house water pressure, if possible or add an appropriate pump to system. Please contact an APEC Representative for assistance.
  • Low water temperature (below 77 degree F) > Increase house water pressure or add pump to compensate for low (cold) water temperature. Temperatures can affect Read more

Tank is full of water but there is very little or no water coming out the faucet.

If you are experiencing very little or no water coming out the drinking water faucet, but have a full tank, the first thing to check is the tank. The tank may be low on air pressure or have a ruptured (torn) bladder.

Locate the blue or black plastic cap on the bottom side of the tank. Fully unscrew the cap to expose the metal air stem valve. Read more

Sluggish Or Very Low Water Flow At RO Dispensing Faucet

Once the system is installed, if you experience sluggish or very low water flow out of the RO dispensing faucet, please review the possible factors below.

  • Insufficient water pressure (see RO Basics for explanation) > Check water pressure. If the water pressure is too low for this chosen RO model, either increase your water pressure or add pump to RO system. Please contact an APEC Representative for support. Read more
