Drain Line Flow Control—Service
Located on the drain connection of the valve, the purpose of the drain line flow control 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.
The flow washer pictured above is installed within a special nipple. Occasionally, the Drain Line Flow Control 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
1. WATER LEVEL in the brine tank
a. Empty
b. Below level of safety valve
c. At level of safety valve float
2. SAFETY VALVE in brine tank
a. Fiberglass rod travels up and down freely (approximately 1/2”)
b. Fiberglass rod is rigid
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 con-
trol. 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 specifi-
cation in Appendix C,
.
