Troubleshooting - First Sales OXY2-10 Installation Instructions And Owner's Manual

PROBLEM
Excessive pressure
drop through filter
Water is colored
from the tap
Clear water turns
colored after drawn
Oxy media fails to
raise pH sufficiently

Troubleshooting

CAUSES
A) Filter not
backwashing
B) Filter bed loaded
with sand
C) Insufficient
backwash
D) "Cementing" or
"Channeling"
E) Control Valve
plugged with debris
A) Leaking bypass
valve
B) Internal valve leak
C) Distributor not
seated properly in
control valve
D) Water usage flow
rate exceeds filter
specifications
E) Insufficient
backwash
A) Insufficient air draw
B) Plugged injector or
injector screen
C) Open or leaking
bypass valve
D) pH too low
A) Water usage flow
rate is too high to
provide adequate
contact time
B) Additional steps are
needed to effectively
raise pH

SOLUTIONS
1) Check timer motor and replace if faulty
2) Ensure uninterrupted power supply
3) Check Backwash frequency setup
4) Verify sediment being removed is less
dense than the filter media and install a
"Spin-Down" type sediment filter ahead of
the filter to remove well sand
5) Increase frequency of backwash
6) Increase length of backwash and rinse
cycles
7) Verify adequate pumping rate for backwash
8) Probe media bed to check for "Cementing"
9) Check drain line for restriction: frozen,
plugged, kinked, exceeds 15', overhead
installation, flexible drain line, drain line
diameter too small
10) Disassemble and clean control valve
1) Verify bypass valve is in service position
and inspect seal, replace if needed
2) Replace spacers and seals
3) Verify distributor tube seated securely in
control valve body
4) Verify actual water usage flow rates against
system specifications
5) Verify adequate pumping rate for backwash
6) Increase frequency of backwash
7) Increase length of backwash and rinse
cycles
1) Verify air draw check valve is functioning
properly and replace if needed
2) Check drain line for restriction: frozen,
plugged, kinked, exceeds 15', overhead
installation, flexible drain line, drain line
diameter too small
3) Verify adequate pumping rate for backwash
4) Increase air draw time
5) Remove and clean injector & screen
6) Verify bypass valve is in service position
and inspect seal, replace if needed
7) Test pH. Must be 7.0 or higher or 8.2 or
higher if Manganese is present
(also see next troubleshooting section)
1) Verify actual water usage flow rates against
system specifications
2) Add MpH Adder to media tank
3) Install a chemical feed pump system ahead
of the filter with Soda Ash
