Your water softener finally quit. Maybe the control head failed, maybe it stopped regenerating, maybe it is twenty years old and you are done hauling salt bags in from the car. So you call a plumber to swap it out for a new one, and the plumber tells you something you were not expecting.
You cannot replace it.
That is how most homeowners in Ontario, Chino and the surrounding cities find out this rule exists. Standing in the garage next to a dead unit, with a plumber explaining an ordinance nobody mentioned when they bought the house. This article covers what the rule says, what you can install instead, how the removal rebate works, and what a salt-free conditioner will not do for you.
Your Softener Died and You Cannot Replace It
Here is the part that catches people. The unit in your garage was almost certainly legal when it went in. Units installed before the ordinance took effect are grandfathered, which means you can keep running one for as long as it works.
The restriction bites at replacement. The moment your unit fails and you want a new one in its place, you are no longer maintaining a grandfathered system. You are installing a new one, and that is prohibited. Same for a homeowner who never had one and wants their first.
So the practical situation is this. If yours is running, keep it. If yours just died, you need a different plan, and you probably need it this week because you are already living with the water.
What the IEUA Ordinance Actually Says
The Inland Empire Utilities Agency ordinance prohibits the new installation or the replacement of self-regenerating water softeners. Existing units are grandfathered and may keep operating.
It covers seven cities: Chino, Chino Hills, Fontana, Montclair, Ontario, Rancho Cucamonga and Upland. If your address is in one of those, this applies to you. If it is not, it does not, and we come back to that below.
The reason is brine. A self-regenerating softener flushes itself on a cycle, and every cycle sends salt down the drain. That water goes to the regional treatment system, and from there into recycled water and the Chino Basin groundwater underneath these cities. Salt is easy to put into water and expensive to take back out. IEUA reports that removing it at the treatment end costs considerably more than the salt ever cost the homeowner who bought the bag.
The agency did not invent this authority on its own. California AB 1366 is the state law that lets local agencies restrict or prohibit residential self-regenerating softeners where salinity in the wastewater stream is a demonstrated problem. IEUA acted under that framework.
Worth saying clearly: none of this is about drinking water safety. The water arriving at your house already meets state and federal standards. The ordinance is about what happens to the wastewater on the way out, not the supply on the way in.
The Removal Rebate, and How to Ask About It
If you decide to take your old unit out, ask IEUA about their removal rebate before you pay anyone to haul it away. This is the part most homeowners do not know exists.
According to IEUA, the program pays up to $2,000 for a qualifying working unit, with the amount depending on the make, model and age. The low end starts around $300. IEUA also reimburses up to $250 toward the plumbing work to disconnect and remove it.
There are conditions worth knowing before you get your hopes up. IEUA requires that the unit be connected and working at the time it is verified. A softener that has already been ripped out and is sitting in the side yard will not qualify. They also require proof of purchase. So if you are reading this because your unit just failed, do not disconnect anything yet. Call them first.
IEUA runs this program, not us. We do not control the amounts, the eligibility rules or the timeline, and IEUA can change any of it. Contact them at 909-993-1550 or softenerrebate@ieua.org to confirm what your unit qualifies for. We are happy to do the removal and the new installation, but the rebate conversation is between you and the agency.
How Salt-Free Conditioning Actually Works
The compliant option is a salt-free whole-home conditioner. The technology most of these systems use is called Template Assisted Crystallization, usually shortened to TAC.
Here is the plain version. Hard water carries dissolved calcium and magnesium. Left alone those minerals look for a surface to bond to, and they find your pipe walls, your water heater elements and your fixtures. That bonded layer is scale.
A TAC conditioner runs the water across a specially prepared media. The surface of that media gives the dissolved calcium and magnesium a place to gather and form crystals while they are still suspended in the water. Once a mineral has crystallized, it has already done the thing it wanted to do. It is no longer looking for your pipe wall. It stays in the water and washes out the tap.
No salt is involved because nothing is being exchanged. No regeneration cycle happens because there is no resin bed to flush. That absence of a regeneration cycle is exactly why these systems are permitted in the seven cities where salt units are not.
Softener just failed and you are in one of the seven cities? Call IEUA about the removal rebate before you disconnect anything, then call us about what goes in its place. We will test your water first.
What You Actually Get
Scale protection is the main event. Manufacturers report that TAC systems substantially reduce new scale forming on pipe interiors, water heater elements and fixtures. That is the damage that shortens appliance life, and it is what you are buying.
The rest follows from what the system does not need. No salt to buy and carry. No brine tank to check monthly. No drain line to route, which matters more than people expect on a hillside lot or where an HOA restricts drain runs. No electricity. No wastewater from a regeneration cycle.
Running cost is the one that surprises people. Manufacturer figures put the annual operating cost of a salt-free conditioner at roughly $20 to $40, which is essentially the replacement filter cartridge once a year. The comparable figure for a salt softener, once you count the salt itself, generally runs about $190 to $240 a year. Over a decade that gap is not trivial.
Our systems pair the scale protection with whole-home carbon filtration, so the water at every tap is filtered for chlorine taste and odor as well. To be precise about the language: whole-house treatment filters the water. Purified is a word that belongs to reverse osmosis, which treats drinking water at one tap.
What Salt-Free Does Not Do
This section matters more than the last one, because this is where people get disappointed if nobody tells them up front.
A salt-free conditioner does not remove hardness minerals. The calcium and magnesium are still in the water after treatment. They have been changed in form, not taken out.
That means if you test your water after installation, it will still test hard. The grains per gallon reading will not drop. Some homeowners see that and think the system failed. It did not. It was never going to move that number.
You will not get the slippery soft-water feel in the shower. That sensation comes from ion exchange in a salt system, and it is not part of this technology.
And it will not eliminate every spot on your glassware and shower doors. Reduced, in many cases noticeably. Eliminated, no. The minerals are still in the water, so when that water evaporates on a surface, something is left behind.
It conditions. It does not soften. We will not call it a softener and neither should anyone selling you one. If a company tells you their salt-free system softens your water, they are either confused or hoping you are.
Who Should Still Buy Salt, and Where They Legally Can
If soft water is the thing you care about most, the slippery feel, the spotless glass, an actual drop in the hardness reading, then you want a salt softener. We will say that plainly even though we sell the other thing.
The question is whether you are allowed to install one, and that comes down to your address. The prohibition covers seven San Bernardino County cities. It does not cover the rest of our service area.
Homeowners in the Temecula Valley, including Temecula, Murrieta, Menifee and Lake Elsinore, can install a salt softener. So can homeowners in Corona and Eastvale, both of which are in Riverside County and border the restricted zone without being in it. Redlands is in San Bernardino County but is not an IEUA city, so salt units are permitted there too. And all of San Diego County is clear.
That catches people regularly. You can stand in an Eastvale driveway a few minutes from Chino, where a homeowner cannot install what you can. Same region, different rules.
How Hard Is the Water Around Here?
Hardness is measured in grains per gallon, and anything above 10 grains is classified very hard.
Temecula and Lake Elsinore measure 15 to 25 grains per gallon. That is roughly double the very hard threshold and among the hardest water in Southern California. San Diego County averages about 16 grains. Bonita, on the Sweetwater Authority system, measures 10 to 15 grains, which works out to 172 to 248 parts per million.
For the Inland Empire cities we have not published a figure, because we have not measured hardness there consistently enough to stand behind a number, and readings across the Chino Basin vary by well field. So we test at your hose bib before we quote anything. It takes a few minutes and it is worth more than any citywide average.
One honest note. At 20 grains a salt-free conditioner is being asked to do a lot. It still protects against scale, which is the expensive damage. But if you have that kind of hardness and you are allowed to install salt, a softener will give you more.
What to Do Next
If you are in one of the seven cities and your unit just failed, do two things. Call IEUA at 909-993-1550 or email softenerrebate@ieua.org before you disconnect anything, because the unit generally has to be connected and working to qualify for a rebate. Then call us and we will look at the install.
If you are outside those cities and deciding between salt and salt-free, the factors are your hardness reading, whether you can route a regeneration drain, and whether you are on septic. We will test and tell you which way your house points, including when the answer is that you do not need a system.
Either way you get a flat written price before we start. Call Pipe Dream Plumbing at (858) 330-2881.
