Start with what you see
Is it hard water — or something else?
Hard water leaves clues all over the house. Match what you notice to the fix, and skip paying for a system that does not solve it.
Salt-based softener
White crust on faucets, showerheads and glass doors
That is calcium and magnesium left behind as water dries. A softener takes them out before they reach the fixture.
Salt-based softener
Spots on dishes and a cloudy film on glasses
Classic hard water spotting. Softened water rinses clean, and the dishwasher needs less detergent to get there.
Salt-based softener
Soap that will not lather, and a film after showering
Hardness minerals react with soap and shampoo. Soft water lathers with less and rinses off cleaner.
Softener or conditioner
A water heater that pops, rumbles or runs out sooner
Often scale and sediment in the tank. Treating the hardness slows new buildup — the tank still needs a flush.
Salt-free conditioner
You want scale protection without salt bags or a drain
A conditioner changes how minerals behave so they cling less to pipes and heaters. It does not make water feel soft.
Neither — that is filtration
Pool smell or a chemical taste from the tap
That is the chloramine disinfectant. A softener will not touch it; carbon filtration does. See water filtration.
What is in the tap water
How hard is San Diego and Big Bear water?
Very hard, in both places. City of San Diego water averages about 14 grains per gallon. Big Bear’s well water averages about 15 — and swings widely from one well to the next. On the Water Quality Association’s scale, anything over 10.5 grains is very hard.
Hardness is not a health problem — both water systems met every drinking water standard. It is a plumbing and appliance problem: minerals that turn into scale buildup, hard water stains and soap scum. Every figure below comes from each utility’s latest published water quality report.
Scale buildup in the water heater
Heating hard water drops calcium carbonate out as scale. It settles in tank heaters and coats tankless heat exchangers, costing efficiency and years of life.
Hard water stains & spotting
The white rings on shower glass, faucets and dark counters are minerals left behind as water dries. Softened water dries without them.
Soap & detergent that works harder
Calcium and magnesium bind with soap, so you use more and it leaves a film on skin, tile and laundry. Soft water fixes the chemistry.
Mineral buildup in fixtures & appliances
Clogged aerators and showerheads, cloudy dishwasher glassware, crusted valves and ice makers. Calcium buildup adds a little every day.

Whole-house water softeners
Water softener installation in San Diego
A whole-house water softener goes on the main line where water enters the house — usually in the garage or along the side yard — so every faucet, shower, water heater and appliance gets soft water. A tank of resin beads does the softening; a brine tank of salt recharges it automatically.
We plumb it so front hose bibs and irrigation can stay on hard water: no salt spent on the lawn, and no softened water on your plants.
Salt-based softener installation
A residential water softener sized to your hardness, household and flow, with bypass valve, shutoffs and a code-compliant drain.
Salt-free conditioner installation
Scale protection on the same main-line loop, with no brine tank, drain or outlet. More on salt-free.
What it takes out
The minerals behind scale, spots and soap scum — at every tap in the house.
Taste and smell are a filtration job. Softening vs. filtration.
What the install includes
Plumbed into the main line so it can be serviced without shutting the house down.
Loop, location & power
Many San Diego homes already have a softener loop in the garage. No loop? We add one.
Salt-based ion exchange
How a salt-based water softener works
Ion exchange is a simple trade. Resin beads hold on to calcium and magnesium and hand back a little sodium in their place. Every so often the softener rinses the beads with brine to reset them.
01
Service
Hard water flows through the resin tank. The beads grab calcium and magnesium, and soft water goes on to the house.
02
Metering
The control valve counts gallons and starts a regeneration only when the resin is close to full — not on a fixed timer.
03
Regeneration
Brine from the salt tank washes the resin, flushing the hardness to drain and recharging the beads. Usually overnight.
04
Refill
The brine tank refills with just enough water to dissolve salt for the next cycle. Bypass keeps water on the whole time.
Why metered regeneration matters in California
Older timer softeners regenerate on a schedule whether you used water or not. A metered valve regenerates only when needed, which saves salt and water and sends less brine down the drain — the direction California’s softener efficiency rules push. We set the salt dose for efficiency, not maximum capacity.
Hard water solutions, side by side
Salt-based softener vs. salt-free conditioner
Both are whole-house hard water treatment. Only one removes the hardness. The third card is here because it gets confused with both.
A straight answer on salt-free systems
A salt-free water conditioner is not a water softener, whatever the box says. The better ones — TAC systems — protect plumbing and heaters well, but the calcium and magnesium are still in the water, so glass can still spot and soap will feel the same. If spotting is what bothers you, salt-based is the fix. We skip magnetic and electronic clamp-on devices; their results are too inconsistent to recommend.
Salt-free water conditioners
Salt-free water conditioner installation
If you want to protect against scale without hauling salt, a salt-free water conditioner needs almost no upkeep. There is no brine tank, drain line or outlet, and nothing goes down the sewer, so it fits where a softener will not.
We install combination systems like the Halo 5. They pair whole-house filtration with salt-free scale control, so one system handles San Diego’s two most common complaints: chloramine taste and hard water scale.
Filtration + conditioning in one
Sediment and carbon stages remove chloramine, taste and odor. A salt-free stage keeps minerals from sticking.
No salt, no drain, no power
A simple main-line install with a bypass valve, and no salt to add each month.
How salt-free conditioning works
It does not remove calcium and magnesium. The media turns them into microscopic crystals that rinse through instead of sticking to pipes and heating elements.
A good fit when…
Salt-free is often the right hard water solution. It is not the right one for everyone.
Installation & upkeep
Installed on the main line like a softener, with less to maintain.
Big Bear: installed in heated space. Tanks and valves can freeze.
Combo system or softener + filter?
If scale protection and filtered water are enough, a salt-free combo like the Halo 5 does both with the least upkeep. If you also want water that feels soft and glass that dries spot-free, pair a carbon filter with a salt-based softener. We test your water and explain both options before you choose.
Two different services
Water softening vs. water filtration
A softener changes what the minerals do to your house. A filter changes what you taste and smell. Plenty of San Diego homes want both — and the order they go in matters.
Water softener
Treats hardness at every tap. Best when the complaint is scale, spots, soap scum or appliance buildup.
Water filtration
Treats what is dissolved or disinfecting the water. Best when the complaint is taste, smell or drinking water quality.
Getting both? Carbon goes first.
A carbon filter ahead of the softener protects the resin from chloramine and gives you filtered, soft water at every tap. Add under-sink reverse osmosis if you want low-sodium drinking water. See water filtration systems.
Water hardness testing & sizing
Sized from your water, not a sales chart
The right water softener system comes from three numbers: how hard your water is, how many people use it, and how much flows at once. The first step is a water hardness test at your tap.
4
people in the house
75 gal
per person, per day
14 gpg
San Diego hardness
4,200
grains of hardness a day
That home usually lands on a 1.5 cubic-foot softener — often sold as a 48,000-grain unit — set to regenerate about once a week at an efficient salt setting. Then we check peak flow, so pressure holds with two showers and the washer running.
Water hardness testing
We test at a tap, not from a map. It takes minutes and sets every number that follows.
Why size matters
Both mistakes cost you. We size for the middle.
Flow & pressure
A softener that chokes the main line is worse than none. Valve and tank are matched to your fixtures.
Replacement & service
Water softener replacement in San Diego
Most softeners last 10 to 15 years. On water this hard, the resin works every day, and plenty of units in San Diego garages have been running on old timer valves for far longer than that.
We tell you honestly whether it is a repair or a replacement. When the existing loop and bypass are sound, a new unit usually goes in on the same connections — often in a few hours.
Signs it is failing
Hardness gets through slowly, so these creep up.
When to replace
Replacement usually wins when the core parts are worn out.
Old unit hauled away; loop, bypass and drain corrected if needed.
Water softener service & repair
Plenty of problems are fixable, and we fix them when they are.
Maintenance
Keeping a softener working
Five minutes a month and a check-up once a year. We write the schedule down for your system at install.
Monthly
Check the salt
Keep it a few inches above the water line. Clean pellets dissolve evenly and leave less residue.
Every few months
Look for bridges
A hard crust can form over empty space in the brine tank. Break it up, and check the drain line and air gap.
Yearly
Test & tune
Test hardness at a tap, clean out the brine tank, and confirm the valve settings and clock.
As needed
Resin care
Resin cleaner where iron is present, and a new hardness setting if your water source changes.
Salt or potassium?
Sodium chloride pellets are standard and cost the least. Potassium chloride works in the same softener with no sodium added; it costs more and needs a higher setting, which we adjust for you.
Big Bear Valley
Big Bear water softener installation
Big Bear’s water comes from dozens of local wells rather than imported supply, so hardness depends on which wells feed your street — anywhere from about 4 to 24 grains in the DWP’s latest testing. Big Bear hard water treatment starts with a test at your tap.
Well water
Hardness and iron vary by well
Some wells carry iron above the aesthetic limit. We test for it and size the softener and resin care around it.
Freeze-safe
Installed where it cannot freeze
Softeners, brine tanks and drain lines go in heated space — never an open crawlspace or an exterior wall at 7,000 feet.
Cabins & rentals
Set up for part-time use
Metered regeneration so an empty cabin wastes no salt, a full salt tank before winter, and a bypass for shutdowns.

Common questions
Water softener FAQ
Is a water softener the same as a water filter?
No. A water softener removes the calcium and magnesium that cause scale, spots and soap scum. It does not remove chlorine, chloramine or most dissolved solids — that is filtration, a separate system. Many San Diego homes have both: a carbon filter in front for taste and smell, then the softener.
Salt-based softener or salt-free conditioner — which should I get?
If you want spot-free glass, better lather and water that feels soft, choose a salt-based softener. It is the only one of the two that actually removes hardness. If your main goal is protecting pipes and the water heater from scale, with no salt, drain line or power, a salt-free conditioner is a good fit. It will not stop spotting.
Is a salt-free water softener worth it in San Diego?
It can be, if scale is your main concern. On San Diego water, at about 14 grains, a good salt-free conditioner greatly reduces scale in water heaters, tankless units, fixtures and pipes, with very little upkeep. It will not make water feel slick or stop all spotting. If those matter most, a salt-based softener is the better choice.
Can one system filter and condition the water?
Yes. Combination systems such as the Halo 5 put sediment, carbon and salt-free conditioning stages together on the main line, so every tap gets chloramine removal and scale control. They do not soften the water or lower dissolved solids — add under-sink reverse osmosis for that.
What size water softener do I need?
It depends on your hardness, how many people live in the house and your peak water flow. Multiply people by about 75 gallons a day, then by your hardness in grains per gallon. A family of four on 14-grain San Diego water uses about 4,200 grains a day, which usually means a 1.5 cubic-foot softener set to regenerate about once a week. We confirm it with a hardness test at your tap.
Will softened water taste salty? Can I drink it?
It should not taste salty. A salt-based softener adds a small amount of sodium — roughly 8 milligrams per liter for every grain of hardness it removes. Most people drink it without noticing. If you are watching sodium, add under-sink reverse osmosis for drinking water, or run the softener on potassium chloride instead of salt.
How often do I add salt, and what kind?
Most homes add a bag or two a month, depending on hardness and how much water the house uses. Keep the salt a few inches above the water line and use clean pellets. Potassium chloride works as a sodium-free alternative; it costs more and needs a higher setting.
Are salt-based water softeners allowed where I live?
In most of San Diego County and the Big Bear Valley, yes. California lets local agencies restrict self-regenerating softeners where brine discharge causes problems for wastewater or recycled water, so we confirm the rules for your address before we install. Either way, we set up metered, salt-efficient systems.
How long does a water softener last?
Usually 10 to 15 years, depending on hardness, iron and upkeep. The resin wears out and older control valves get harder to find parts for. If yours is in that range and the spots have come back, replacement usually makes more sense than repair.
Do I still need to flush my water heater if I have a softener?
Yes, but far less scale collects. A softener stops new mineral scale from forming, but sediment already in the tank stays until it is flushed out. We can flush the tank the same day we install the softener. See water heater services.
