Drain Line Flow Control—Service
Located on the drain connection of the valve, the purpose of the drain line flow controller is to regulate the up flow
backwash required to expand and agitate the resin in the softener. The softener will allow maximum expansion
of the resin, while preventing any loss to the drain.
The flow control principle is simple and trouble free. The specified rate of flow will be constant regardless
of inlet pressure variations.
Occasionally, the Drain Line Flow Controller may become plugged with scale, rust, or other foreign material.
If this occurs, cleaning is required. This can be done while the softener is in SERVICE and under pressure.
Brine System Analysis
If the brine system is functioning properly, there will be water in the brine tank, but the level should be
below the safety valve float and the fiberglass rod should travel freely. If these conditions do not exist,
one of the following conditions will indicate the nature of the problem:
1. NO WATER IN BRINE TANK—ROD TRAVELS FREELY. The flow control is plugged.
Remove refill flow control. Clean or replace.
2. NO WATER IN BRINE TANK—ROD IS RIGID. Air or water slammed the safety valve closed before
water could enter the tank. Clean parts at the base of the brine safety valve and also make sure that
the seat of the check valve in the brine line is clean. Check for possible air leaks in the brining system.
3. WATER IN BRINE TANK UP TO SAFETY VALVE FLOAT—ROD IS RIGID. There are possible causes:
a. Brine piston is not in service position when control is in service or brine piston seals are defective. Remove
brine line while in service. There should be no flow to brine tank.
b. Refill flow rate is too high or refill time length is too long. Check refill flow rate
and compare to specification in
c. Brine tank is smaller than the recommended size. Refer to
