There is standing water in the brine tank which I have never noticed before. Is this normal?

Yes, it is normal to have some standing water in the brine tank of a US Water Systems Fusion. However, excessive water in the brine tank could indicate an issue, such as an improper salt setting or a plugged brine line flow control. If excessive water is present, troubleshooting steps like checking the salt setting and cleaning the brine tank may be necessary.

Page 5 Installation, Operation and Maintenance Manual How the Softener Works The principle behind water softening is simple chemistry. A water softener contains resin beads which hold electrically charged ions. When hard water passes through the softener, calcium and magnesium ions are attracted to the charged resin beads. The result is remov- al of calcium and magnesium ions which produces soft water.
Page 6: Tank Preparation
EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Pip- ing that is built up heavily with lime and/or iron should be replaced. LOCATION OF FUSION TANK AND DRAIN: The Fusion tank should be located close to a drain to pre- vent air breaks and back flow.
Page 7 It is recommended that a dust mask and safety goggles be worn to prevent possi- ble injury. A shop vacuum can be held in the area to help control the dust created by the filling process. Pour all the resin that was shipped in the tank. US Water Systems DOES NOT ship extra resin.

Then install the upper basket on the bottom of the valve by lining up the tabs then turning the basket clockwise to lock it in place. Place the upper basket over the distributor tube and push the valve on the tank.
Page 9 Installation, Operation and Maintenance Manual 7. Lubricate the O-rings on the bypass valve and 1” threaded connectors. Remove the red clips and install the bypass on the control valve. Re-install the red clips once the bypass is in place. Put the bypass valves in the bypass position (picture shows “Service Posi- tion”, see page 18 for valve position) 8.
Page 10 Installation, Operation and Maintenance Manual Note: As the picture shows, connect the inlet and outlet according to the arrow direction which can be seen from the top view of the control valve. The installation of 1“ integrated bypass valve： If the 1” integrated bypass is used instead of a three manual valve, the instal- lation method is shown in the picture below.

It is a good practice to add a sediment filter pri- or to the Fusion system between the pressure tank and the Fusion tank.
