If your Long Beach home has hard water spots on the glassware, scale crusting the shower head, dry skin after every shower, or a chlorine taste at the kitchen tap, you're dealing with the reality of Southern California municipal water. Alliance installs whole-house water softeners, carbon filtration, and reverse osmosis drinking water systems for single-family homeowners across Long Beach. We're a family-owned plumbing company based in Fontana, serving Los Angeles and Orange County, and we solve the problem the first time with upfront pricing and same-day service when your schedule needs it.
What water treatment system installation involves
Long Beach water comes in hard — typically 10 to 17 grains per gallon — and treated with chloramine. A proper water treatment install starts with matching the equipment to your actual water and household size. For most single-family homes we install a two-stage system: a whole-house carbon tank or cartridge filter to pull out chlorine, chloramine, and sediment, followed by an ion-exchange water softener sized to your bathroom count and peak flow.
The physical install ties into the main cold water line, usually where the service enters the garage or side yard. That means cutting in a bypass loop, running a drain line for the softener regeneration cycle, adding a 120V outlet if one isn't nearby, and setting up a brine tank on a level pad. If you also want treated drinking water, we add a four- or five-stage reverse osmosis unit under the kitchen sink with its own faucet and a dedicated line to the fridge. Every install ends with a pressure test, a leak check on every fitting, programming the softener head to your hardness reading, and a walkthrough so you know how to add salt and when to change filters.

Our water treatment installation process
- Phone consult. Tell us your address, number of bathrooms, and what problem you're trying to solve — spots, taste, scale, or all three.
- On-site water test and walkthrough. We test hardness and chlorine at your tap, look at the main line location, drain access, and electrical, then recommend a system.
- Written estimate. Flat price for equipment and install, in writing, before we schedule the job.
- Installation day. We shut down the main, cut in the bypass, set the softener and filter, run the drain and electrical, and mount the RO unit if included. Most whole-house installs finish in 4–6 hours.
- Startup and programming. We charge the resin, run a manual regen, program hardness and regen schedule, and sanitize the RO membrane.
- Walkthrough. You learn where the bypass is, how much salt to add, and when to swap the sediment and carbon cartridges.
- Follow-up. We check back after the first regeneration cycle to confirm soft water at every fixture.
What water treatment system installation typically costs
Whole-house water treatment is a wide price range because the equipment and the plumbing situation both vary. A basic single-tank softener installed on an accessible main line is a very different job from a twin-tank softener with a carbon backwash filter and a reverse osmosis drinking station. Estimates in Long Beach range based on the system type (softener only, softener plus carbon, salt-free conditioner, or full softener + RO combo), the grain capacity you need for your household, whether we need to add a drain line or electrical outlet, and how the main line is configured at your home.
Included in every Alliance quote: the equipment, all fittings and shutoffs, the bypass valve, drain and electrical hookup, startup, and cleanup. Not included: repairs to unrelated existing plumbing we find behind the wall. Request a free on-site estimate and we'll price the exact system your water and home need.

Frequently asked questions
Do I really need a whole-house softener in Long Beach?
Long Beach water regularly tests in the "hard" to "very hard" range. If you're seeing white scale on faucets, spotting on dishes, or short water heater life, a softener will noticeably change all of that.
Softener or salt-free conditioner — which is better?
A traditional ion-exchange softener actually removes hardness minerals and gives you slick, soft water. A salt-free conditioner changes the crystal structure to reduce scale but doesn't soften. We'll show you both on the estimate and let you choose.
Where does the softener drain go?
Regeneration wastewater usually ties into a nearby laundry standpipe, condensate drain, or exterior drain within code-approved distance. We handle the routing during install.
Will a softener affect my drinking water?
Softened water contains a small amount of sodium. Most homeowners who want pure drinking water pair the softener with a reverse osmosis system at the kitchen sink, which we can install in the same visit.
How long does the install take?
A whole-house softener with carbon filter is usually a half-day job. Adding an under-sink RO adds about 90 minutes.
Do you offer any current promotions?
Yes — free estimates on new water treatment installations, plus Senior and Veteran discounts year round.
