If you've noticed a chalky, scummy buildup on your plumbing fixtures, you already know how tough it is to shift hard water deposits. This common household nuisance is down to calcium, magnesium and other minerals in your water supply. Unfortunately, a stubborn residue on your kitchen and bathroom faucets is just the tip of the iceberg — a much more serious plumbing problem could lurk beneath the surface.

Water conditioners offer a possible solution to this chalky conundrum. Let's explore how much a water conditioner costs and how these units protect your plumbing system.

What Is a Water Conditioner?

Water conditioners alter the hardness particles in your water supply to prevent them from building up in your plumbing system. Some models also reduce the amount of chlorine and other chemicals in your water. They could be a good option if you live in a hard water area because calcium, magnesium and other hard minerals can accumulate inside pipes and fixtures, potentially leading to clogs and other plumbing issues.

There are several types of water conditioners available. The most common types include:

Template-assisted crystallization conditioners pass the water over resin beads, transforming hardness ions into harmless crystals.
Electrochemical conditioners treat water with an electric current to break down hardness ions and chemicals.
Electrically induced precipitation conditioners use an electric current that causes hardness ions to attach to an electrode.

Some water conditioner manufacturers claim to remove hardness minerals with magnets. However, the scientific evidence surrounding magnetic water conditioners is uncertain, and they may not work as effectively as more established systems.

Water Conditioners Vs. Water Softeners

Many homeowners confuse water conditioners with water softeners. To add to the confusion, some manufacturers refer to water conditioners as salt-free water softeners. The key difference is that water softeners remove hardness particles from your water supply, while water conditioners chemically alter them to make them less harmful to your plumbing system.

Traditional water softeners require salt to operate, and you'll need to replenish the salt from time to time to keep your unit functioning effectively. Water conditioners don't require salt, so they cost less to run and maintain.

On the other hand, water conditioners don't remove hard minerals, so you won't achieve true water softness. They can be a great option if your main goal is to prevent scale from developing in your pipes and fixtures, but a water softener may be more suitable if you experience skin irritation or other issues caused by hard water.

How Much Does a Water Conditioner Cost?

According to HomeGuide, template-assisted crystallization water conditioners cost between $400 and $4,000 (CAD 540 and CAD 5.430), excluding the cost of installation labor. Expect to pay toward the lower end of the price range for a small under-sink unit to condition the water supplying a single fixture. Whole-house water conditioners cost toward the upper end of the scale and are powerful enough to condition your entire water supply.

Electronic and magnetic water conditioners are significantly cheaper. Most homeowners pay between $160 and $600 (CAD 216 and CAD 810) per unit.

How Much Does It Cost to Have a Water Conditioner Installed?

How much a water conditioner costs to install depends on several factors, including the size of your unit and where you want it installed. Plumbers typically charge $45 to $150 (CAD 61 to CAD 203) per hour to install a home water conditioner. Expect to pay a licensed electrician $50 to $130 (CAD 68 to CAD 176) per hour if you require wiring or outlet upgrades to power your new unit.

Most homeowners pay $150 to $250 (CAD 203 to CAD 338) to have a professional install a water conditioner system. These figures include labor and equipment but exclude the cost of the water conditioner itself. Expect to pay an extra $50 to $100 (CAD 68 to CAD 135) to remove and dispose of an existing unit. You could spend more if your plumbing system is challenging to access or you need to install new pipes to accommodate your water conditioner.

You won't need to hire a professional plumber to install most electronic or magnetic water conditioning systems. That's because these units are easy to attach to the outside of a pipe, making them suitable for DIY installation.
