How to install or "hook up" a water softener:

How to connect a water softener to building water piping, drain piping, & electrical power; where to locate the water softener. This article explains how to hook up a water softener or water conditioner.

We describe the piping connections for water in and out of the water softener, water softener bypass valves for maintenance, and water softener drain hookups.

This article series explains how water softeners and similar water conditioners work, types of water softeners, and the basics of what water softener controls are present and what they do, how water softeners should be installed, maintained, cleaned, and adjusted.

How Water Softeners or Water Conditioners are Hooked Up to Building Plumbing

Kinetico water conditioner installation (C) Daniel FriedmanIt is conceptually simple to install and connect-up a water conditioner or water softener.

You need to find physical space where the resin or treatment tank and controls will fit, and where the salt or brine tank will fit. Usually these two pieces are separate (except in some older manually operated water softeners), but they are installed side-by-side.

Our photo of a water conditioner installation at left shows a Kinetico Mach Series water conditioner system installed in a Dutchess County New York home.

Where space is really tight, we sometimes see the larger brine tank installed somewhere else not right next to the water softener, but of course connected to it by its flexible plastic tubing.

Guide to Connecting A Water Softener Water Piping or Input and Output Water Lines

Water sofener hookup - CulliganSince it's usually preferable to treat all of the building water supply with a water conditioner (this helps protect pipes from mineral-clogging by hard water), the water conditioner is usually placed as close as possible to where water enters the building.

Most installers place the water softener near other water equipment in the building such as close to an indoor pump and water pressure tank, or where municipal water is supplied, close to where the water supply enters the building.

The water softener hookup layout sketch shown at left is from a 1989 Culligan System 19 or 23 Water Conditioner installation manual. Be sure to consult the specific manual for your own water softener brand and model for correct hookup details for your own equipment.

The water softener is piped "in line" on the main cold water pipe entering the structure so that incoming water is treated before passing on to the building water heater, and to hot and cold water distribution piping.

If other water treatment or water sterilizing or potability system is installed (such as a chlorinator or UV light), that equipment is best placed ahead of or before the water softener to help avoid the chances of unwanted bacterial growth in the water conditioner.

If a water filter is installed, we like that to also be ahead of all other water treatment in the building to help avoid debris clogging that interferes with proper operation of other water treatment equipment. For example, dirt or silt in a water supply can quickly coat the bulb in a UV light bacterial treatment device on a private water supply system.

Incoming water is connected to the "input" side of the water softener/water conditioner, and the conditioner's output side is connected to the building water supply piping feeding the building's plumbing fixtures.

For watering gardens and lawns the installer may provide a direct connection to that building water piping taken off before the water softener so that we don't waste water softener salt treating water being used to wash a car or water the lawn.

How & Where to Connect the Water Softener Drain Line

Water softener drain line length and psi - CulliganPeriodically, depending on the water hardness and the amount of water used, the water softener or water conditioner needs to clean itself of minerals accumulated as they were removed from the water supply, and to recharge the salt used in the softener's resin chamber where water is treated.

[Click to enlarge any image or table]

On an automatic water softener the regeneration and cleaning cycle for the water softener is controlled by a simple timer or clock, or on more sophisticated systems a computer chip may monitor the amount of water used and even the hardness of water leaving the system, deciding based on that data when a backwash-regeneration cycle is needed.

Shown at left is a chart indicating the water softener drain line length limitations in feet based on an installation in which the brine tank and water softener are installed together on the same building level.

This specific chart is from a Culligan System 19/23 Water Conditioner installation manual. Be sure to check your own equipment's installation manual.

When the water softener goes through a regeneration cycle it will bypass the building water supply, often automatically, so that water stops passing through the equipment's treatment system pump water into the separate brine tank (salt tank) where it dissolves salt pump new salty water backwards through the resin tank or treatment tank where the process removes other minerals from the treatment tank, sending this product out through a (usually plastic) drain tube to a building drain.

Other water conditioner manufacturers such as Autotrol specify other drain line connection details

Warnings: Avoid These Water Conditioner Drain Connection Mistakes

Plumbing cross connection (C) Daniel Friedman



Cross connection of water softener to sewer line (C) Daniel Friedman

Watch out: Use an air gap: for elevated water conditioner drain lines that empty into an overhead sewer pipe or waste pipe you should use a sink-type trap for the connection (that is provide an air gap to avoid back-contamination of the equipment).

Watch out: Never connect the water softener drain line directly to a sewer drain (that is by an air-tight connection such as shown at left).

Doing so invites sewage and bacterial back-contamination into the building water supply system, especially if a sewer line backup occurs.

See CROSS CONNECTIONS, PLUMBING.

Connecting Water Softener Electrical Power

The water softener also needs to be plugged-in to an electrical outlet to power the equipment control.

See Steps in Starting Up A New or Newly-Installed Water Softener for details.

Setting up the Water Softener & Setting Its Controls

You'll need to set the water conditioner's clock to the proper time (and day on some models) and you may need to set the water softener controls that determine the frequency of regeneration and the salt dose.

See WATER SOFTENER ADJUSTMENT & CONTROLS.

Steps in Starting Up A New or Newly-Installed Water Softener

The following advice is adapted from water softener installation manuals from Culligan and other water conditioner manufacturers.

For new water conditioners: The water conditioner start-up procedure here is appropriate when you are installing a new water conditioner system or a new water conditioner media tank.

Watch out: as Culligan's manuals point out about new water conditioners,

A sanitizing agent has been added to the conditioner tank [the media tank or resin tank] at the factory. This sanitizing agent must be flushed out before the unit is placed into service, by initiating a recharge cycle using the steps outlined below.

  1. Plug in the power cord: Check that the water conditioner timer or control is in the "service" position, then plug in the water conditioner's power cord to an electrical outlet.

    You should use a grounded outlet that will accept a grounded electrical cord plug (a three-prong plug). If necessary you can use a three-prong to two-prong adapter to connect to a two-prong electrical receptacle, but be sure that that receptacle is itself grounded. In general, a three-prong to two-prong electrical outlet adapter includes a green metal tab with a hole in it that is used to make a proper connection to the electrical grounding system.

    The screw in the center of the cover plate for the electrical receptacle is removed and reinserted through the green tab so that the adapter is secured in place and a ground connection is made. We recommend that you ask your electrician to install a grounded, three-prong electrical receptacle in that location as soon as convenient.
  2. Set the water conditioner controls: set the timer to the correct time of day, time of recharge, recharge frequency, and set the "salt dose" or refill regulator to the proper number.

    See WATER SOFTENER ADJUSTMENT & CONTROLS for details.
  3. Open the bypass valve: with the controls set for normal service, slowly open the water inlet valve or slowly open the bypass valve if it was in the closed or "bypass" position. On a Culligan water softener this means push slowly on the blue knob on the bypass valve to put the unit into service.
  4. Allow water to fill the resin tank.
  5. Perform a water softener regeneration cycle. On a typical Culligan model this may mean rotating the cam that carries the "salt dosage" dial 1/3 turn, or pushing a red "regen" button on the water conditioner timer.

    Note: more detailed instructions in your water conditioner installation or user's manual may explain the need to move the salt dosage cam to start a regen cycle or to return the cam to a normal between-cycle position.
  6. Drain and refill the hot water tank? If hard, untreated water entered the building's hot water tank while the water softener was on bypass or turned off, then you should drain and refill the hot water tank.

    Watch out: Be sure that the water heater is turned off before and during drainage and refill.

List of Free Water Softener & Water Conditioner Installation Manuals

Watch out: because water softener and other water conditioner equipment models vary in features and functions, they also vary in their exact installation requirements. You should have or obtain the installation, operation, and maintenance manual for your own brand and model of water softener.

Most water softener owners manuals include detailed installation instructions and also a table of recommended settings. If you don't have an owner's manual call the manufacturer's tech service and give them the model number and ask for a manual as well as their setting advice.

Digital control head on Kinetico water softener (C) InspectApedia.com DawnDawn:

Right, that Kinetico water softener uses electrical power; if you ripped the power cord out or off of the control head, a new cord will need to be attached; Some dis-assembly of the control head may be required, and at that time the repairperson will check to assure that the control board to which the power cord connects was not itself damaged.

Watch out: if you are not familiar with proper and safe electrical work then you need to hire a repair tech to do the job safely as you could be shocked or killed.

It does use power it's all digital

On 2020-10-04 by (mod) - lost electrical power cord to Kinetico water softener

Dawn:

A water softener that uses electricity normally comes with a power cord and wall plug attached.

There are some water softeners that don't use electricity and that are operated entirely by water pressure.

What are the brand and model of your water softener?

I see your photos;

do we know where the no-longer-used drain line goes?

On 2020-04-11 16:45:23.915456 by Bob

Drain line above unit in original installation. Now drain line rerouted thru wall, and at least 2-3 feet down exit pipe behind wall. System seems to be working fine. I was just curious about position of drain line. I took photos. Where do I send ?

On 2020-04-11 - by (mod) -

I'm not sure, Bob - a photo or drawing would help. If we're discussing a water softener drain connection that has been abandoned you may simply want to cap it.

Also I'm not sure which "tanks" you're referring-to.

WIthout more details about your installation I can but guess that perhaps the original high routing for a condensate drain line was both convenient to install and worked acceptably because condensate was being moved with a condensate pump.

A Kinetico system is a water treatment or water softener - a system that, during regeneration cycles will produce way too much water to be handled by a simple condensate drain tube, and furthermore ought just be dumped on to the ground surface as might be done with a low volume A/C condensate disposal system.

On 2020-04-11 by Bob

I had an issue with a pipe in the wall, a hole that was the result of faulty installation of my a/c unit. The drain line for my KINETICO system drained into this pipe. Because of this I rerouted the drain line, to go further down the damaged pipe.
My question : is there a reason the original placement (exit) of the drain line, was in the wall ABOVE the tanks ? I rerouted it so that it now goes into the wall BELOW the unit, and then out into the pipe . Thanks 520-419-6735. docpoppi@aol.com

Nancy,

It's possible that the softener is not properly adjusted.

Try first running the softener through an extra regen-cycle.

Next, most softeners have a procedure that lets you start that regen cycle again but skip ahead to the final rinse cycle.

Run that rinse cycle and report back to me if that's solved the salt taste issue.

On 2020-01-24 by Nancy Golden

I just had a water softner professionally installed. Since then the tap water has a chemical/salt taste
