PROBLEM
POSSIBLE CAUSE
SOLUTION
1)
Water CLEAR when
drawn, turns RED
upon standing (Stain
producing).
A.
Insufficient air injection.
A.
Check for proper compressor operation.
B.
Bypass open or leaking.
B.
Close bypass valve and/or repair as necessary.
C.
Filter bed overloaded with precipitated iron due
to insufficient backwash, or failure to backwash
due to malfunction of control timer or unplugged
control valve power cord.
C.
Upon correction of problem (increase backwash
frequency if problem determined to be insufficient
frequency), manually backwash until backwash water
starts to clear (in more severe iron fouling cases, filter
bed may need chemical cleaning- contact Customer
Care Team at 855-3M-WATER (855-369-2837).
D.
Presence of manganese or tannins.
D.
Recheck water analysis.
E.
Flow rate excessive for model.
E.
Reread section 2, FACTS TO REMEMBER WHILE PLAN-
NING YOUR INSTALLATION, page 2-1.
F.
pH of treated water too low (should be 7.0 or
higher; with manganese, pH must be 8.2).
F.
Replenish MpH component in media (contact Customer
Care Team at 855-3M-WATER (855-369-2837).
2)
Water RED when
drawn from tap.
A.
Filter bed overloaded with precipitated iron due
to insufficient backwash flow rate.
A1.
Recheck well pumping rate and repair or replace as
required.
A2.
Check for obstructions or kink in drain line.
A3.
Check 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 Customer Care Team at
855-3M-WATER (855-369-2837).
B.
Filter bed overloaded with precipitated iron due
to insufficient backwash, or failure to backwash
due to malfunction of control timer or unplugged
control valve power cord.
B.
Upon correction of problem (increase backwash
frequency if problem determined to be insufficient
frequency), manually backwash until backwash water
starts to clear (in more severe iron fouling cases, filter
bed may need chemical cleaning — contact Customer
Care Team at 855-3M-WATER (855-369-2837).
C.
Aeration tank installed too far from media tank
causing iron to precipitate before media tank.
C.
Relocate to a location closer to filter inlet.
3)
Excessive pressure
loss through filter.
A.
Filter bed overloaded with precipitated iron.
A.
Refer to Section 2 above.
B.
Control bypass valve not fully open.
B.
Open as necessary.
C.
Sand, silt or mud collecting in filter bed.
C.
Check well for these conditions.
D.
Filter bed not properly “classified.”
D.
Manually backwash to reclassify.
E.
“Cementing” or “channeling” of filter media.
E.
Prod (stir) filter bed to break up hardened layer. Increase
backwash frequency to prevent reoccurrence.
4)
“Milky” or “bubbly”
water (appears to
contain small bubbles
which do not quickly
dissipate).
A.
Excess gases in water (Carbon Dioxide,
Hydrogen Sulfide, Methane).
A.
May require draining of water system or installation
of air relief control on the fillport cap of valve adapter
base, (contact Customer Care Team at 855-3M-WATER
(855-369-2837).
