How to Install a Water Softener System? & Other Water Softener FAQs

If you’re considering installing a water softener, you likely have questions like “How do I install a water softener?” and “What size water softener do I need?” To help you make the most informed decision when deciding on (or selecting) a water softener system, we’ve answered the most frequently asked questions we get from our clients about water softeners. From water softener system installation to long-term maintenance, these nine FAQs will help you get started!

1. How Does a Water Softener Work?

A water softener removes minerals like calcium and magnesium from your water supply. These minerals cause hard water, which leads to scale buildup in pipes and appliances. The system uses a resin bed that attracts and traps hard water minerals while exchanging them for sodium or potassium ions. Over time, the resin bed needs to be cleaned through a regeneration process, which flushes the trapped minerals and replenishes the sodium or potassium (see FAQ #7 below: How to Maintain a Water Softener).

2. Do I Need a Water Softener?

A water softener can improve your home’s plumbing and water quality if you have hard water. Benefits of softened water include:

• Prevents scale buildup in pipes, appliances, and fixtures.
• Extends the lifespan of water heaters, dishwashers, and washing machines.
• Reduces soap scum on dishes, sinks, and showers.
• Provides softer skin and hair by preventing mineral deposits.
• Improves soap efficiency, making it easier to lather and rinse.

3. How Much Does a Water Softener Cost?

The cost varies depending on the system’s size (see #4 below: What Size Water Softener Do I Need?) and features. A basic water softener typically costs between $150 to $1,500, while high-end systems with advanced features may cost more.

4. What Size Water Softener Do I Need?

The right size depends on your household’s water usage and hardness level. A typical home needs a softener with a grain capacity of 24,000 to 48,000 grains per cycle. Larger households or homes with extremely hard water may require a higher capacity. Additionally, some people opt to install a water softener for their whole home, while others may want just a single system for their preferred sink or shower.

5. How to Install a Water Softener?

If you’re wondering how to plumb a water softener, follow these general steps:

1. Shut off the water supply and drain the pipes.
2. Determine the location (see #6 in the next section: Where to Install a Water Softener).
3. Cut into the main water line and install a bypass valve.
4. Connect the water softener using plumbing fittings.
5. Attach the drain hose to a proper drainage point.
6. Add salt to the brine tank and run a regeneration cycle.

For best results, follow the directions on the water softener system you purchased (obviously!). Alternatively, you can use a professional plumber to ensure a proper and leak-free water filtration system installation.

6. Where to Install a Water Softener?

This really depends on what type of water softener system you install. Like we mentioned earlier, some people install a filter in their primary sink or shower while others opt for a whole-home solution. If the latter, often the ideal location is near the main water line entry point, typically in a basement, garage, or utility room, and it should be near a drain for regeneration discharge (and near an electrical outlet, if needed).

7. How to Maintain a Water Softener?

Regular maintenance ensures your water softener system runs efficiently. First and foremost, check the instructions that came with the system (or follow the instructions given by the plumber who installed it). In general, here’s what you’ll likely need to do:

• Check and refill the salt in the brine tank as needed.
• Clean the brine tank every 6-12 months.
• Inspect for salt bridges (hardened salt formations) and break them apart if necessary.
• Schedule professional servicing by a plumber for optimal performance.

8. How Long Do Water Softeners Last?

Most water softeners last 10 to 15 years, depending on water hardness, usage, and maintenance. High-quality systems with regular upkeep can last even longer.

9. How to Replace a Water Softener?

If your water softener has reached the end of its lifespan, here’s how to replace a water softener:

1. Turn off the water supply and disconnect the power.
2. Drain and disconnect the old unit.
3. Install the new softener, connecting it to the same plumbing and drainage lines.
4. Run a regeneration cycle before using the system.

Again, for a seamless, leak-free replacement, hiring a professional plumber is highly recommended.
