How to Install a Water Softener. Doing your own plumbing may not be for everyone, but it can be for you. Projects such as installing a water softener, are not as difficult as they may appear. Read the directions, have the proper tools and exercise a great deal of patience. You are all set to successfully install your water softener.

Prepare to Install a Water Softener

Step 1

Open the box and read all the directions to install a water softener. Assemble your tools and get ready to impress your spouse with your plumbing skills.

Step 2

Turn off the water at the main shutoff valve. Also turn off the electricity to your hot water heater. Verify that the shutoff valves work properly by attempting to turn on the faucet.

Step 3

Drain your water lines by opening all the plumbing fixtures, even those that are outdoors.

Step 4

Situate your water softener in an area that is dry, safe and level. In the case of a two tank softener, position the brine (the larger one) and the resin tanks near one another.

Install the Water Softener

Step 1

Insert the distributor tube into the mineral tank. Flush the open end (top) with the tank and rest the screen intake on the bottom's center point.

Step 2

Tape open the tubes to prevent the tiny beads (media) from entering the distributor tube.

Step 3

Pour enough gravel (if included) slowly through a funnel into the tank to cover the screen intake.

Step 4

Add softener resin to fill the tank between one-half and three-quarters full, then take the tape off the distributor tube.

Step 5

Affix the top basket to the control valve's underside and then to the mineral tank. Lubricate the inner o-ring prior to attaching the head to the tank. The hole in the middle of the valve should fit over the distributor tube. Tighten the valve by hand in a clockwise motion.

Connect the Water

Step 1

Attach the bypass valve to the control valve by aligning their in and out arrows. Tighten the screws so that the stainless clamps on the valve and bypass are seated.

Step 2

Join the softener's water connections to the bypass. After affixing three-eighth-inch plastic tubing to the brine tank's fitting, run it into a drain.

Step 3

Fill the brine tank with about four gallons of water and plug in the control valve. Add 40 pounds of sodium chloride or potassium chloride salt.

Step 4

Set your softener to the backwash stage and the bypass valve into the service position. Open the water supply valve one-quarter of the way to permit air to run off from the drain line.

Step 5

Open the water supply valve completely once a steady flow of water from the drain appears.

Step 6

Run the softener through an entire backwash cycle.

Step 7

Examine your softener for leaks and/or loose fittings.
