Brine Pump Replacement
The brine pump has been specifically designed for this application. All metal parts in contact
with brine are made of Hastelloy, which is a nickel-based alloy impervious to brine. The
pump is magnetically coupled to the motor. To avoid brine leakage into the magnetic
coupling housing, all seams are sealed.
The fluid connections to the pump are made with 3/8” diameter polypropylene tubing via
John Guest type push-in tube fittings. The fittings are 1/4” male NPT threaded connections
into the pump head. The inlet and outlet ports of the pump are identified by the flow arrow
stamped into the end of the pump head. The inlet port has a push connect swivel elbow and
the arrow head end is the outlet end.
Removing The Old Brine Pump
1. Put the system in standby by pressing the red mushroom button on the control panel.
2. Wait for the system to complete purging and go into standby status.
3. Disconnect the electrical connector by following the cable from the pump to the top of
the plumbing enclosure. While pushing the back of the cable towards the top of the
enclosure, pull the locking collar and the plug out of the receptacle.
4. Remove the 3/8” poly tube from both sides of the pump head with the push-in fitting.
The tube is removed by holding the gray collar against the body of the fitting, and
pulling the tube out of the fitting.
5. With a #2 Phillips head screwdriver, remove the 4 screws that hold the pump to the
panel in the plumbing compartment. Remove the pump.
