Troubleshooting

Complaint
1. Iron or manganese* bleed‑
through or staining
Sulphur odor bleed‑through
*Manganese can be slow to oxidize when the pH is less than 8.5
20
Problem
A. Inadequate backwash of filter
B. Fails to regenerate
C. Water contaminant levels are
greater than limits established by
the manufacturer
D. Inadequate aeration
Cause
1. Plugged drain line flow control
2. Insufficient water supply from
well
3. Plugged aeration tank inlet dif-
fuser or pick‑up tube
4. Media bed fouled
1. Interrupted electrical service
1. It is not uncommon for local
water conditions to change
1. Loss of air through inlet check
valve
2. Loss of air through air leak
3. Faulty aeration pump due to:
a. Electrical failure
b. Pneumatic failure
c. Damp environment
4. Air loss through high demand
5. Relay does not energize air
compressor
Solution
1a. Clean or replace drain line flow
control
2a. Check for minimum specified flow
and pressure requirements of filter
system
3a. (Generally will only plug with the
presence of iron bacteria) Clean aera-
tion assembly and shock treat the
water supply with chlorine as needed
to control iron bacteria
4a.
Rebed filter and correct the cause of fouling
1a. Assure continuous electrical supply
(check plug, breaker, fuses, etc.)
1a. Consult dealer
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
2a. Check aeration tank assembly for
any air leaks and repair (Note: soapy
water solution works well for locating
air leaks)
3a. Assure permanent electrical service
(check plug, breaker, fuses, terminal
block on control valve, etc.)
3b. Check for adequate pressure and
volume production from air pump.
Repair or replace air pump
3c. Clean, repair or replace aeration
pump, ventilate environment or pro-
vide external air source
4a. Increase air recharge frequency of
filter. See page 6
5a. Verify correct programming‑see page 9
5b. Wired incorrectly from PC board. See
wiring diagram‑page 14
. Faulty relay. Verify 12V DC power at
terminals 1 & 5.
5d. Faulty PC Board. No power to rly 1
and common or rly2 and common
