What are the Different Parts of a Water Softener?

Posted by

In order to make a smart buying decision, it helps to know the product you are buying (especially if you install it yourself). Here is a quick guide to knowing what each part of a water softener is, and a brief explanation of it!

Hard Water Supply 

This is the hose through which the hard water passes through, and enters the processing chamber. This processing chamber is also known as the resin tank or the mineral tank.

Soft Water to House

This is where your soft water will distribute to your home. Through this valve, the softened water is passed for the household tasks.


After the softening process is completed, the water softener stops working with the calcium and magnesium ions on the resin beads. To remove them, the regeneration process takes place where the brine solution is added to the mineral tank. Calcium and magnesium ions are removed from the beads, and they are drained out form this tube.

Fleck Head 5600sxt

The head is where you will put in all your calculations. It monitors water flow and manages the operation of the water softener. For example it will have you set your water hardness and how often the system will regenerate.

Mineral Tank

These are also known as resin tanks. The resin tank is where water is softened and incoming hard water passes through ion exchange resin process. Resin swaps the calcium and magnesium in the water for the sodium or potassium they are holding. When the swapping happens the water is becoming soft.

Outlet Manifold

You will find this within the mineral tank. The manifold is a tube or pipe within the tank which will get smaller pipes or channels. The manifold has a direction moving outside on this system.


These are beads that filter contaminants from your water. These beads are placed in the mineral tank, in which the primary ion exchange process takes place. The calcium and magnesium ions present in the hard water get stuck ot these beads because of the opposite charges on them. After the softening process ends, the beads are regenerated by brine solution.

Brine Tank

The brine tank is where you add the salt. This tank should be filled at least 50% of the way to ensure there is enough salt in the system to soften your water. During the regeneration process in water softeners, the brine solution passes into the mineral tank, to recharge the beads which are covered with the calcium and the magnesium ions.


This is what is present in the brine container. Its job is to help regenerate the resin beads.

Float/Valve Assembly

You will find this assembly in the brine tank system. The brine float is on top of the brine valve, it rises with the brine during brine production to prevent the brine well from overfilling. The brine valve assembly is inside the brine well and it controls the brine water level.

Brine Line

Brine (salt) is drawn into the valve with the educator and injected into the top of the softener tank. The brine flows down through the resin exchanging the sodium portion of the salt for the hardness ions collected on and in the resin bed. This cycle continues until all the liquid in the brine tank has been drawn into the softener tank.

Brine Well Tube

The brine well is inside the salt storage tank houses the brine valve assembly. The brine well prevents the salt pellets from interfering with the brine valve’s operations.
