Troubleshooting Guide
Complaint
Problem
Cause
Solution
Hydrogen Sulfide
and/or "rotten
egg" odor
Iron staining
appearing on
fixtures
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 inlet strainer
3. (Generally will only plug with the
presence of nuisance bacteria.) Clean
inlet strainer 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 recondition 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 filter tank, control valve, air
suction line, check valve and fittings for
air leaks and repair (Note: soapy water
solution works well for locating air leaks)
a. Electrical failure
a. Assure permanent electrical service
(check plug, breaker, fuses, terminal
block on control valve, etc.).
b. No Air Draw
b. Check air strainer and eductor assy.
for presence of restriction.
4. Air loss through high demand . 4. Increase reconditioning cycle
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.
