Step 2. Use the filter housing wrench to unscrew the filter
housing that is leaking. Make sure the O-ring is
seated correctly inside the filter housing groove.
You may also want to apply some Vaseline around
the O-ring. This will help secure the O-ring in the
filter housing groove.
Step 3. Re-attach the filter housing to the RO head. Hand
tighten the housing, then use the filter housing
wrench and simply give an additional quarter inch
turn. Do Not over tighten the housing.
Step 4. Open the tank ball valve and feed water line.
Check for leaks. If the filter housing contin-
ues to leak, please contact APEC technician for
replacement assistance.
9) Filter Housing Is Leaking
If you are experiencing a leak from any of the pre-filter housings on the reverse osmosis system,
the rubber O-ring may be defective. The filter housing must have an O-ring in order to seal
properly. Please review the steps below to address a leaking filter housing.
Please follow the steps below:
Step 1. Shut off the feed water line to the RO unit. Turn off the tank ball valve by turning the
Blue Cap on the tank ball valve 90 degrees.
Test #1 TDS from tank: Dispense some water from the RO faucet, this water comes directly from
the tank. Test TDS, record the reading, then Do Test #2.
Test #2 TDS bypassing tank: Turn OFF tank valve. Disconnect the Yellow line from the tank’s
valve. A stream of filtered water will trickle out of the Yellow line. Let the water trickle freely for
about 1 minute, then Catch some water here and do a TDS test. The TDS here is the actual “real
time TDS”
the RO is producing before water enters the tank. Compare this TDS reading with the
tank’s TDS you get in Test #1.
If tank TDS is higher than Yellow line TDS, that means your source water’s TDS level fluctuates
over time. So, from day to day, the TDS highs and lows accumulate in the tank resulting in a high
“composite TDS” reading. This is especially true if you’re on a private well. The well pump’s
fluctuating pressure cycles also cause TDS to go up and down. In this case, the “real-time” TDS
from the Yellow line (prior to the tank) is the system’s true performance. If this number is within
10% of your tap TDS, then it is within an acceptable range, and your RO system is working fine.
Drawing more water can help stabilize the TDS. If you are only drawing a small amount of water
every time, the unit will quickly turn On and Off, not allowing the membrane to receive full inlet
pressure, causing a spike in the TDS.
