Complaint Problem Cause Solution
A. Dirt lodged under seat of valve
B. Faulty or defective relief valve
A. This can be expected when water
is aerated under pressure
A. See complaint #1 problem A & B
A. Inlet check valve not sealing
A. Reduced pressure in distribution
system
A. New filter backwashed during first
24 hours after installation
B. Air passing through filter during
backwash
A. Howling or whistling noise during
regeneration cycle
A. Control valve is stuck in regenera-
tion cycle
A. Corrosive water condition in copper
distribution piping system
Air spurting from filtered water
fixtures
Water leaking from relief valve
Water is effervescent
1. Pressure has exceeded rating on
relief valve and caused valve to
open
1. Water supply has been naturally
aerated under well system
pressure. As water is released
to the atmosphere, air molecules
separate from the water molecules.
1. Improper installation location
2. Foreign material preventing check
valve from sealing
3. Worn or faulty check valve
1. Service flow demand is greater than
water supply available from well
pump system
2. Water flow is restricted by supply
piping and/or water treatment
equipment
1. New filter media is shipped in a dry
condition and must soak for 24
hours to become fully saturated
before a backwash cycle
1. Excess air accumulated in aeration
tank from aeration pump
2. Excess air accumulated in filter
system from water supply or well
pump
1. Inadequate drain line size
2. Drain line is vibrating against other
pipes, conduits, pipe hangers, heat
ducts, floor joists, etc.
1. Electrical service to control(s) has
been interrupted
2. Faulty timer motor
3. Foreign material lodged in piston
4. Timer is lodged in regeneration
cycle
1. Low pH condition of the raw water
supply. On type "A" filters, the pH
correction media may be depleted
2. In rare occasions, highly aerated
water in combination with a specific
water supply can create a slightly
corrosive condition
Loss of pressure
Air spurting at outside or non-
filtered water fixtures
Loss of media through drain line
Excessive noise during
regeneration
Water running to drain
continuously
1a. Check pressure on system. Adjust
if necessary. Clean or replace
relief valve.
1a. Replace valve
1a. This natural phenomenon will typi-
cally dissipate to the atmosphere in
a matter of seconds. If preferred,
water can be drawn and stored in
an open container prior to use (i.e.
fill a pitcher and store in the refrig-
erator for cool fresh drinking water)
1a. See installation and operation
manual for proper location of inlet
check valve
2a. Clean or replace check valve
3a. Replace check valve
1a. Repair or replace well pump
system
2a. Eliminate restrictions in supply
pipings to water treatment
equipment such as iron bacteria
plugging the upper diffuser
assembly, etc.
2b. Install larger water treatment
system to provide less pressure drop
1a. Clean drain line flow control,
control valve body, seals, spacers
and piston assemblies
1a. Bleed-off valve flow control is
plugged with foreign material –
clean or replace
2a. Repair well pump system
2b. If the cause was due to temporary
loss of water main pressure; the
problem will most likely correct
itself with the return of continuous
pressure
1a. Increase drain line size
2a. Insulate drain line, specifically at
points of contact with other
materials
1a. Assure continuous electrical
service is available (check plug,
breaker, fuse, etc.)
2a. Replace timer motor
3a. Disassemble and clean control
valve, replace seals, spacers, and
piston assemblies
4a. Check program wheel pins, to
assure back pins are not catching
on timer gears
4b. Check to assure timer gears are
clean and free from foreign ma-
terials such as solder or pipe burrs
1a. On type "A" filters add pH
correction media to filter tank, see
Installation and Operation manual
2a. Install a polyphosphate cartridge
filter after the Iron Curtain Filter
System to protect the distribution
piping
