Water Softener Installation & Whole-House Filtration
Southern California runs some of the hardest water in the country. In parts of our service area it reaches 15 to 25 grains per gallon. Water softener installation is how a home stops paying for that, in scaled pipes, short-lived water heaters, and spotted glass. All Star Plumbing installs softeners, conditioners, whole-house filtration, and drinking-water reverse osmosis, each sized to your household. The service call costs $0, and the price comes in writing first.

One honest line before the sales pitch you won’t get: a salt-free “conditioner” is not a softener and doesn’t remove hardness. Both have their place. We’ll tell you plainly which fits your home. (Treatment is planned work. A system or line actively leaking is our emergency line, 60-minute response.)
What is water softener installation?
Water softener installation is the fitting of an ion-exchange system into a home’s main water supply: a plumbing loop where the softener sits, a drain line for its regeneration cycle, and power. The softener itself removes hardness minerals, calcium and magnesium, by swapping them for sodium on a resin bed. It’s the lead system in home water treatment, alongside salt-free conditioners, whole-house carbon filtration, and under-sink reverse osmosis. All Star Plumbing installs and services all four.
No Service Call Fee
It costs nothing for us to come out, look over your setup, and talk through the options. Written estimate before any work.
Sized to Your Household
Systems are sized by how many people use the water and how hard it actually is, measured, not guessed.
A Conditioner Is Not a Softener
We describe every system by what it actually does. If the cheaper option fits your goal, that's the one we'll recommend.
Which water treatment systems do we install?
Four systems, four different jobs. Hard water treatment starts with knowing which problem you're actually solving, then matching the system that honestly does that job and no more.
Salt-Based Water Softener
The only system here that truly removes hardness. An ion-exchange resin bed swaps calcium and magnesium for sodium, then regenerates with a salt brine. Scale stops forming because the minerals are gone.
- Removes hardness, actually
- Protects heaters, pipes, and fixtures
- Needs a drain, power, and floor space
Salt-Free Conditioner
Honestly named: a conditioner, not a softener. It doesn't remove hardness. It changes the minerals (template-assisted crystallization) so they cling and scale far less. Simpler to install, minimal upkeep.
- Reduces scale, keeps minerals in
- No salt, no drain, no power
- The low-maintenance option
Whole-House Carbon Filtration
A different job than softening. A whole house water filter tackles chlorine, taste, odor, and sediment, in every tap and shower. Often paired with a softener, because each handles what the other can't.
- Chlorine, taste, odor, sediment
- Every fixture in the house
- Pairs naturally with a softener
Reverse Osmosis Drinking Water
Point-of-use purity at the kitchen sink. An under-sink RO system removes up to about 97% of dissolved solids from the water you actually drink and cook with. The finishing touch on a treatment setup.
- Under-sink, at the tap you drink from
- Up to ~97% of dissolved solids removed
- The answer to the sodium question
Repair & Replacement
Already own a system? We service what's there: softeners stuck in regeneration, exhausted resin beds, clogged filters, RO membranes past their life, and replacements when a unit is done.
- Existing systems diagnosed
- Filters, membranes, and resin serviced
- Replacement quoted honestly
What Hard Water Is Doing Meanwhile
Scale narrowing pipes and crusting fixtures. Water heaters rumbling toward early replacement. Spotted glass, stiff laundry, soap that won't lather, dry skin and hair. Hard water isn't dangerous, it's just expensive.
- Scale in pipes, heaters, and fixtures
- Shorter water heater life
- Spots, soap scum, dry skin and hair
How do we pick and install the right system?
Water treatment has a reputation for oversell: the biggest stack of tanks for every home. Our process is built to resist that. Measure first, match the system to the actual problem, size it to the household, and put the whole thing in writing.
Five steps from tap to treated.
Test the water you actually have
Hardness in grains per gallon, plus the chlorine taste and sediment picture. The measurement is the foundation. A home at the top of the local hardness range needs different capacity than one at the bottom.
Match the system to the problem
Scale damage points to a softener (or a conditioner, honestly framed). Taste, odor, and chlorine point to carbon filtration. Drinking-water purity points to RO. They're different jobs, and naming yours correctly is most of the decision.
Size it to the household
Capacity comes from people times water use times measured hardness. Undersized systems regenerate constantly and wear out. Oversized ones waste money up front. We size to the math, not the margin.
Plan the install realities
A salt-based softener needs a drain for regeneration, power, and about five square feet of space. It also needs a plumbing loop, which we add if your home lacks one. A salt-free conditioner needs none of that. Either way you'll know the full install scope, in writing, before work.
Install, commission, and hand over
The system goes in, the loop is plumbed cleanly, and we commission it: hardness verified at the tap on a softener, flow and pressure checked, filter and salt routines explained in plain words before we leave.
Salt-based, salt-free, or neither: an honest guide.
The right answer depends on what you're solving for, and sometimes the honest answer is the cheaper system, or a different one entirely. Here's the guide we'd give a friend.
Whichever way it points, the $0 visit and a written quote come before any decision.
You want hardness gone: salt-based softener.
It's the only option here that removes calcium and magnesium rather than managing them. Spotting, scale, and soap scum stop at the source. The trade: salt refills, a drain, power, and floor space.
You want less scale with zero upkeep: salt-free conditioner.
No salt bags, no drain, no power, and meaningfully less scale on heaters and fixtures. What it won't do is remove hardness, and we won't pretend otherwise. It's the honest middle option.
Your complaint is taste, smell, or chlorine: carbon filtration.
A softener won't fix taste, and a filter won't fix scale. Chlorine, odor, and sediment are filtration's job, whole-house, at every tap and shower.
You care most about drinking water: reverse osmosis.
An under-sink RO delivers the purest water in the house exactly where you drink and cook, removing up to about 97% of dissolved solids. It's the precision tool, not the whole-house one.
You're on a low-sodium diet: know this trade-off.
A salt-based softener adds some sodium to the water. For most households it's minor. If sodium matters in yours, the standard answer is an RO tap for drinking water, or a salt-free conditioner instead. We'll lay out both.
Your heater is already scaled up: treat, and service the heater too.
Treatment stops new scale, it doesn't remove years of sediment already baked into a water heater. Pairing a new system with a heater flush is how the improvement actually shows up in hot water.

Quick and knowledgeable. They walked me through the process and were great to work with
John and his crew were amazing. I had a problematic service. He didn't give up. I appreciate all he did to restore my water for me and my daughters! Thank you John!!
Super great service and friendly workers. It was super easy to set up a time for them to come and they completed the work in a timely manner. Will continue to recommended them to my family and friends and will use them in the future if anything else happens!!
What sets the price of a water treatment system?
Treatment pricing is mostly the system itself plus the install scope, and both are visible before you commit. The $0 visit is the service call and a visual assessment of your setup. The written estimate itemizes the equipment and the plumbing work separately. Here's what moves the number.
What the estimate is built from
Which system, and how many
A single conditioner is the simple case. A softener is more. A full stack (softener plus whole-house carbon plus an RO tap) is the top end because it's three systems doing three jobs. You choose the ambition level with the numbers in front of you.
Capacity
Bigger households and harder water need higher-capacity units. The size comes from your household's water use and your measured hardness, so the quote reflects your water, not a default.
The plumbing work your home needs
A home with an existing loop, a nearby drain, and power at the spot is a clean install. Adding a loop or running a drain line is honest extra scope, and it appears as its own line on the estimate.
New install, or service on an existing system
Reviving a good unit with fresh resin, filters, or a membrane costs a fraction of replacement, and when that's the smarter money, it's what we'll quote first.
Does a salt-free water conditioner actually soften water?
No, and anyone who says otherwise is selling, not explaining. A salt-free conditioner changes hardness minerals (template-assisted crystallization) so they form far less scale. But the calcium and magnesium stay in the water, so hardness isn’t removed. Only a salt-based softener removes hardness. Conditioners are still a genuinely good option, they just deserve their real name.
How does a water softener actually work?
Ion exchange. Water passes through a tank of resin beads charged with sodium. The beads grab calcium and magnesium and release sodium in trade. When the resin fills up with hardness minerals, the system regenerates. It rinses the beads with salt brine and flushes the hardness down the drain. That cycle is why a softener needs salt, a drain, and power.
What size water softener does my home need?
It’s a calculation, not a shelf pick: people in the household, times daily water use, times your measured hardness in grains per gallon. Around here hardness commonly runs 15 to 25 gpg. That’s exactly why sizing starts from your real measured hardness instead of an assumption. Undersized units regenerate constantly and die early. Oversized ones just cost more up front.
Does softened water taste salty, and how much sodium does it add?
It shouldn’t taste salty: the sodium added is modest, proportional to how hard your water was. But it’s real, and for low-sodium households it’s worth taking seriously. The standard solution is an under-sink RO tap for drinking and cooking water, which removes the sodium along with everything else. Or choose a salt-free conditioner instead. We’ll walk you through both honestly.
What's the difference between a water softener and a whole-house filter?
Different jobs entirely. A softener removes hardness minerals. It fixes scale, spotting, and soap scum, but does nothing for taste. A water filtration system (whole-house carbon) removes chlorine, odors, and sediment. It fixes taste and smell, but does nothing for hardness. That’s why homes with both complaints often run both, in series, each doing its own job.
Is an under-sink reverse osmosis system worth it?
If you care about the water you drink and cook with, usually yes. RO removes up to about 97% of dissolved solids at the one tap where purity matters most. It’s also the cleanest answer to the softener sodium question. What it isn’t: a whole-house solution. It’s a precision tool for the kitchen sink, usually the final piece of a treatment setup.
Will a softener help my water heater?
Going forward, substantially. Hard water packs a heater with sediment, steals its efficiency, and shortens its life. Softening stops that accumulation at the source. What a softener can’t do is remove the scale already baked into an older tank. Pairing the install with a heater flush is how you actually feel the difference.
What does installing a water softener involve?
Three connections. A plumbing loop on the main line where the system sits, and we add one if your home lacks it. A drain line for the regeneration cycle. And a power outlet. Plan on roughly five square feet of floor space, usually in the garage. A salt-free conditioner skips the drain and power entirely, which is much of its appeal. Either way, the full scope is written down before work starts.
