Water Running to Drain
Note:
With softeners and filter/softeners, start by testing the drain water. If the drain water is hard, the tank
currently in service has a problem with its drain valve. If the drain water is soft, start with number 1 below.
Problem
Reason
Solution
1. The balance piston
O-ring is not seated
properly.
Water will leak past an improperly seated
balance piston O-ring and out the drain.
Depress the actuator several
times to seat the O-ring.
Replace worn or non-
conforming O-ring.
2. Bad control disc.
A scored control disc will allow a fast drip
to a pencil sized stream to flow through
the drain.
Replace the control disc.
3. The drain or
control valve seals
are not seating
properly.
Foreign matter under the seals will not
allow them to seat properly.
Disassemble and remove the
foreign matter from seals.
4. Low water
pressure.
If the water pressure is less than 15 psi
(CP208-210) or 25 psi (CP213-216) at the
brine fitting the system may not operate
properly.
Test Backwashing Filters with the unit in
Backwash and 1 faucet (cold) running
water.
Increase water pressure.
5. The Main Valve
piston quad rings or
Level 4 internal quad
rings are not sealing.
The quad rings may be rolled, pinched,
torn or just dirty.
The quad rings may be chloramine or
chlorine damaged if on a chlorine treated
water supply.
Replace and re-silicone the
quad rings.
Replace quad rings with
silicone seals. Order
chloramine kit, part number
10534.
Taste, Color & Odor
Problem
Reason
Solution
1. Treated water has
a metallic or iron
taste
.
See the section entitled "Iron Bleed-
Through".
2. Treated water has
chlorine odor and/or
taste.
This is due to heavily chlorinated raw city
water.
Install a carbon filter.
