REVERSE OSMOSIS TROUBLE SHOOTING GUIDE
Problem Possible Cause Solution
Low quantity of Reverse
Osmosis Product Water from
Holding Tank Reverse Osmosis Feed Water Ball
Valve is plugged or closed. Open Valve or unclog.
Clogged Sediment Pre-filter or
Activated Carbon Pre-filter. Replace Reverse Osmosis filters.
Low water pressure. Reverse Osmosis Feed Water
pressure must be above 40 psig.
Reverse Osmosis. Membrane is
fouled. See Reverse Osmosis Feed Water
operating limits. Correct cause of
fouling, replace Membrane.
Plugged In-Line Activated Carbon
Post Filter. Replace Post Filter.
Air pre-charge pressure in Holding
Tank is too high. Empty water from Reverse
Osmosis Holding Tank, and with
the faucet open, adjust air pressure
to 5 – 7 psig (35–48 kPa) range.
Air pre-charge is too low
Air Bladder in the Holding Tank is
ruptured. Replace Reverse Osmosis tank.
Holding Tank Valve is closed. Open Valve.
No drain flow, the Drain Restrictor
is plugged. Clear or replace Drain Restrictor.
The Check Valve is stuck. Free check.
The ASO Valve is malfunctioning. Replace ASO Valve components.
Low pressure at the Reverse
Osmosis Dispensing Faucet In-Line Activated Carbon Post Filter
is plugged. Replace Post Filter.
Air pre-charge in the Reverse
Osmosis Holding Tank is too low. Empty water from Reverse
Osmosis Holding Tank and with the
faucet open, adjust air pressure to
5 – 7 psig (35-48 kPa) range.
Check for leakage at the Reverse
Osmosis Air Valve Stem.
Reverse Osmosis Holding Tank
Valve is partially closed. Open Valve
The dispensing Faucet is out of
adjustment or faulty. Repair or replace Reverse Osmosis
Dispensing Faucet.
Heavy water use, Reverse
Osmosis Holding Tank is depleted. Allow Reverse Osmosis Holding
Tank to refill (adding a second
Holding Tank will increase storage
capacity).
Low Water Production. See Low Quantity of Product Water
from Holding Tank section above.
High Total Dissolved Solids
(TDS) in the Product Water Clogged Sediment Pre-filter or
Activated Carbon Pre-filter. Replace Reverse Osmosis Filters.
Low Water Pressure. Reverse Osmosis Feed Water
Pressure must be above 40 psig.
Check Feed Water Ball Valve.
Reverse Osmosis Membrane O-
ring is crimped. Check O-ring.
Reverse Osmosis Membrane brine
seal is not sealing up into the
manifold head. Check the brine seal.
Reverse Osmosis Membrane is
expended. If Reverse Osmosis Membrane life
is unusually short, find and correct
the problem. Replace Membrane.
