Complaint
8. Excessive noise during
regeneration
9. Water running to drain
continuously from filter
control
10. Water running to drain
continuosly from 3/8"
bleed off tube on
aeration tank.
11. Blue green staining
22
Problem
A. Howling or whistling noise during
regeneration cycle
A. Control valve is stuck in regeneration
cycle. See specific control manual
A. Did not plug in aeration pump prior
to filling
B. Shuttle valve stuck in the open
position.
A. Corrosive water condition in cop-
per distribution piping system
Cause
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.
Faulty drive motor
4.
Foreign material lodged in piston
5.
Timer is lodged in regeneration
cycle
1. Drain port open
1. Shuttle valve fouled with foreign
material.
2. Excessive pressure from water sup-
ply system causing internal pressure
relief valve to open.
3. Solenoid vent port fouled with for-
eign material or faulty solenoid.
4. Seat on end of piston assembly
dislodged or damaged by foreign
material
5. Vent port connected to bleed off
drain line or filter
6. Faulty timer stuck in the ON position
7. Bleed off tube in aeration tank
restricted.
8. Air pump failed during air recharge
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 aer-
ated water in combination with a
specific water supply can create a
slightly corrosive condition
3. Shorten bleed off tube, reduce
recharge frequency
Solution
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.
Replace drive motor
4a.
Disassemble and clean control valve,
replace seals, spacers, and piston
assemblies
5a.
Check program wheel pins, to assure
back pins are not catching on timer
gears
5b.
Check to assure timer gears are clean
and free from foreign ma‑terials such
as solder or pipe burrs
1a. Plug in aeration pump. (See start‑up
instructions ‑ page 5.)
1b. Clean or replace shuttle valve and
piston assembly
2b. Reduce water supply pressure
3b. Clean or replace solenoid assembly
4b. Clean or replace piston assembly
5b. Vent port MUST vent to an atmospheric
drain site.
6b. Replace timer
7b. Remove aeration head and clean or
replace bleed off tube.
8b. Replace/Repair pump
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
3a.
See page 9 for recharge frequency
changes. Shorten bleed‑off tube
to 9" (Page 8‑ #17)
