Trouble Shooting
Issue Possible Cause Possible Solution
A. Water clear when
drawn; turns red upon
standing (stain produc-
ing) 1. Insufficient air in air tank. a) Increase Brine Time (air draw)
b) Check valve not working.
2. Bypass open or leaking Close bypass and/or repair as necessary.
3. Filter bed overloaded with precipitated
iron due to insufficient backwash Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases,
bed may chemical cleaning - contact dealer.
4. Presence of manganese or tannins Recheck water analysis
5. Flow rate excessive for model Reread "Sizing Requirements" Page 5-6.
B. Water red when
drawn from tap 1. Filter bed overloaded with
precipitated iron due to insufficient
backwash flow rate a. Recheck well pumping rate for backwash and
repair or replace as required.
b. Check for obstructions or kink in drain line
c. For improper drain line flow controller, see specs.
Upon correction of this problem, if
manually backwashing does not clear bed of iron,
filter bed may need chemical cleaning - contact
dealer.
2. Filter bed overloaded with
precipitated iron due to insufficient
backwash Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases,
bed may need chemical cleaning - contact dealer.
3. Insufficient air in air tank. a) Increase Brine Time (air draw)
b) Check valve not working.
C. Excessive pressure
loss through filter 1. Filter bed overloaded with precipitated
iron. See problem above
2. Control inlet/outlet valve(s) not fully
open Open valves
3. Sand, silt or mud collecting in filter bed Check well for these conditions
4. Filter bed not properly classified Manually backwash to reclassify
D. Milky or bubbly water
(appears to contain
small
bubbles) 1. Excess Mazzei injector air draw Check adjustment for duration of draw in
excess of 1/3 pumping cycle.
2. Excess gases in water (carbon
dioxide, hydrogen sulphide, methane) May require draining of water system or
installation of air relief control - contact
dealer.
E. Unit fails to initiate a
regeneration cycle. 1. No power supply. Check electrical service, fuse, etc.
2. Defective circuit board. Replace faulty parts.
3. Power failure. Reset time of day.
F. Low water pressure. 1. Iron or scale build up in line feeding unit. Clean pipes.
2. Iron build up inside valve or tank. Clean control and add resin cleaner to clean bed.
Increase regeneration frequency.
3. Inlet of control plugged due to foreign
material. Remove piston and clean control valve.
G. Filter media in drain
line. 1. Air in water system. Check well system for proper air eliminator control.
2. Incorrect drain line flow control (DLFC)
button. Check for proper flow rate.
H. Valve continuously
cycles. 1. Defective position sensor PCB. Replace faulty parts.
I. Flow to drain continu-
ously. 1. Valve settings incorrect. Check valve settings.
2. Foreign material in control valve. Clean control.
3. Internal leak. Replace seals, spacers, and piston assembly.
