Complaint Problem Cause Solution
Iron bleed-
through or
staining.
A. Inadequate backwash of
filter
1. Plugged drain line flow
control
1. Clean or replace drain line flow control
2. Insufficient water supply
from well.
2. Check for minimum specified flow and
pressure requirements of filter system.
3. Plugged aeration tank
inlet diffuser or pick-up
tube.
3. (Generally will only plug with the presence
of iron bacteria.) Clean aeration assembly
and shock treat the water supply with
chlorine as needed to control iron bacteria.
4. Media bed fouled. 4. Rebed filter and correct the cause of
fouling.
B. Fails to regenerate 1. Interrupted electrical
service.
1. Assure continuous electrical supply (check
plug, breaker, fuses, etc.).
2. Faulty circuit board. 2. Replace circuit board.
3. Faulty drive motor. 3. Replace drive motor.
4. Circuit board set
incorrectly.
4. Reset circuit board.
C. Water contaminant
levels are greater than
limits established by the
manufacturer
1. It is not uncommon for
local water conditions to
change.
1. Consult manufacturer.
D. Inadequate aeration 1. Loss of air through inlet
check valve.
1a. Check installation position of check valve
- Consult Installation and Operation Manual
for proper position.
1b. Check for foreign material in seat of check
valve, clean or replace as required.
2. Loss of air through air
leak.
2. Check aeration tank assembly and air
recharge line and fittings for any air leaks
and repair (Note: soapy water solution
works well for locating air leaks)
3. Faulty aeration pump.
a. Electrical failure a. Assure permanent electrical service (check
plug, breaker, fuses, terminal block on
control valve, etc.).
b. Pneumatic failure b. Check for adequate pressure and volume
production from air pump.
c. Damp environment c. Clean, repair or replace aeration pump,
ventilate environment or provide external air
source.
4. Air loss through high
demand .
4. Increase regeneration frequency of filter.
E. Exceeding recommended
filter system flow rate.
1. Service flow rate demand
is higher than filter
system design flow rate.
1a. Install a flow control at filter system outlet
equal to or less than the design flow rate of
filter system.
1b. Install additional filter(s) or a larger
single filter system which meets both the
service flow demand and backwash flow
requirements available.
