7) There is a leak at the Tank ball valve connection
If you are experiencing a leak from where the tank ball valve attaches to the tank stem, you may not
have applied enough Teflon tape to the stem when you first installed the valve. To correct this issue,
please turn off the supply water to the system and turn on the drinking water faucet to completely empty
the tank. Then, unscrew the tank ball valve and apply 6-8 wraps of Teflon Tape to the tank stem and
screw on the tank ball valve back onto the tank. Please double check the connection for leaks.
8) System Slow Shut-Off: Drain water runs for hours (6-7 hrs) - but Eventually Stops
The most common cause for “slow-shut-off” is insufficient input water pressure. RO needs
sufficient input pressure to shut off promptly.
- Input water pressure too low (below 40psi). Not enough pressure to shut off RO promptly —>
Check input water pressure. If pressure is low, boost house pressure or add pump to RO.
- Feed water valve partially blocked, not opened fully, reducing input water pressure to RO —>
Check and fix feed water valve, make sure it is opened fully to allow maximum pressure to RO.
- Stages 1, 2, 3 pre-filters partially clogged, reducing the input water pressure in RO —> Check stage-1
filter to see if it’s very dirty. If this filter has turned brown or other color in just 1-3 months , that means
your input water has very heavy sediments and other clogging agents. Need to replace stage-1 filter
frequently.
- RO busy feeding multiple output points —> If your RO feeds multiple outlets (icemaker,
bathroom, aquarium), the drain water will run as long as the RO is making water to fill the tank and
other output points. In this case, it’s normal to hear drain water running.
NOTE: Very cold tap water temperature may cause slower shut off
9) System Does Not Shut-Off: Drain water runs all day - and Never Stops
- Input pressure way too low (below 30psi). Not enough pressure to shut off the RO at all —> Check in-
put water pressure. If pressure is below 30psi, need switch to Booster-Pumped RO model. Contact APEC
customer service for assistance.
- If you would like to perform a shut-off test to see if your RO’s shut-off function is working normally,
please perform the test below.
