PROBLEM CAUSE CORRECTION
1. Water clear when
drawn; turns red
upon standing (stain
producing)
2. Water red when
drawn from tap
4. Milky or bubbly
water (appears to
contain small
bubbles)
3. Excessive pressure
loss through filter
A. Insufficient air drawn by the Mazzei
injector
B. Bypass open or leaking
C. Filter bed overloaded with
precipitated iron due to insufficient
backwash
D. Presence of manganese or tannins
E. Flow rate excessive for model
F. Check valve located between
Mazzei injector and pressure tank,
disrupting water flow.
G. Pumping cycle too short
A. Check Mazzei injector adjustment. If
unable to adjust for long enough draw,
check pumping rate.
B. Close bypass and/or repair as
necessary
C. 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.
D. Recheck water analysis
E. Reread "Facts to Remember While
Planning Your Installation" Page 3
F. Relocate check valve.
G. Lengthen pump cycle time.
A. Filter bed overloaded with
precipitated iron due to insufficient
backwash flow rate
B. Filter bed overloaded with
precipitated iron due to insufficient
backwash
C. Mazzei injector drawing too much air
causing early precipitation of iron
D. Mazzei injector installed too far from
pressure tank or pressure tank
located too far from filter tank
E. Solenoid valve malfunction or
inadequate supply system
pressure/flow rate
A. Excess Mazzei injector air draw
B. Excess gases in water (carbon
dioxide, hydrogen sulfide, methane)
A. Filter bed overloaded with
precipitated iron.
B. Control inlet/outlet valve(s) not fully
open
C. Sand, silt or mud collecting in filter
bed
D. Filter bed not properly classified
A. a. Recheck well pumping rate 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.
B. 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.
C. Reduce Mazzei injector air draw
D. Contact dealer for proper location of
Mazzei injector and pressure tank
E. Replace solenoid valve, check specs for
proper pressure/flow rates
A. Check adjustment for duration of draw in
excess of 1/3 pumping cycle.
B. May require draining of water system or
installation of air relief control - contact
dealer.
A. See problem above
B. Open valves
C. Check well for these conditions
D. Manually backwash to reclassify
