Your Home’s Water: Making it Clean and Soft in Orange County

Hi, I’m Brian McCowin. For over 50 years, since 1972, my family at McCowin Water has been helping folks right here in Orange County get the best water for their homes. We know that hard water and hidden stuff in your tap water can cause big headaches. It can make your appliances break down faster, make your water taste funny, and even worry you about your family’s health.

This guide is all about making things clear. We’ll talk about what causes these water problems in places like Irvine, Newport Beach, Laguna Beach, Huntington Beach, Costa Mesa, and even down to San Clemente and Dana Point. We’ll show you how our special water systems; like whole-house filters, water softeners, and reverse osmosis; work to keep your pipes safe and make your drinking water super clean.

You’ll learn to spot hard minerals, chlorine, dirt, and even those tricky new things like PFAS. We’ll help you understand how our systems get rid of them and find the perfect fit for your home, whether you’re in Aliso Viejo, Mission Viejo, or Lake Forest.

We’ll also talk about how we put these systems in, how to keep them running great, and what they cost. We believe in being honest and clear. We’ll even show you why a quick, free test at your home is the best first step. We want you to feel good about your water, knowing you’ve made a smart choice for your health, your home, and your peace of mind.

Call us at (949) 569-5736 or schedule your free water test today.

Ready to See What’s in Your Water?

Let’s find out exactly what your home needs with a quick, no-pressure test.

What’s Really Going On With Your Water in Orange County?

The tap water in our Orange County homes, from Tustin to Fountain Valley, often has a few things that can cause problems. Things like hard minerals (calcium and magnesium) can build up, making your water heater work harder and clogging your faucets.

Chlorine, which cities use to kill germs, can make your water taste and smell funny, and even dry out your skin and hair. Then there’s dirt and rust from the pipes, which can make your water cloudy and wear out your appliances. And sometimes, we find newer things like PFAS that we want to make sure are handled.

Knowing what’s in your water helps us pick the right solution, whether it’s a whole-house filter for all your water or a special filter just for drinking water.

Here’s a quick look at the main things we often find:

  • Hard minerals (like calcium and magnesium): These cause that crusty buildup, making things less efficient and shortening the life of your appliances.
  • Chlorine and chloramines: They keep your water safe from germs, but they can make your water taste bad and leave your skin and hair feeling dry.
  • Dirt and rust: These can clog your filters, stain your sinks, and even harm your washing machine and dishwasher.
  • PFAS and other tricky stuff: These are chemicals that can be a concern over time. Special filters or reverse osmosis are needed to reduce them.

This is why a simple test is so important. It tells us exactly what we need to fix. And guess what? We offer a free in-home water test to show you just that!

Curious About Your Water?

Let’s uncover your water’s secrets together. It’s easy… and free!

What Makes Water Hard and How Does it Hurt Your Home?

Hard water simply means there’s too much calcium and magnesium dissolved in it. When this water gets hot or dries up, these minerals turn into a crusty buildup we call “scale.” You’ll see it inside your pipes, water heater, and on your faucets. It’s like a sticky film that makes soap not lather well. You might notice spots on your dishes, your soap not working as well, hot water taking longer, and even higher energy bills.

Over time, this scale can make your water heater die sooner and cause more plumbing repairs. Catching these signs early means we can get you a water softener that saves you money and hassle. Taking care of this early means fewer repair bills and better-feeling water for your laundry and showers.

How Do Chlorine and Chloramines Affect Your Tap Water?

Your city water company, whether you’re in Santa Ana or Garden Grove, uses chlorine or chloramines to keep the water clean and kill germs. They’re good at that! But chlorine can make your water taste and smell like a swimming pool.

Chloramines are a bit trickier to get rid of. Both can make your skin and hair feel dry and even give your drinking water a metallic taste. Getting rid of these from all the water coming into your home means better showers, cleaner laundry, and happier appliances. We just need to make sure we pick the right filter for what’s in your water.

A good water test helps us know exactly what kind of chlorine is in your water so we can pick the perfect filter for your whole house.

What About Those New Things Like PFAS in Orange County Water?

PFAS and other VOCs are man-made chemicals that can sometimes be found in our water, even in small amounts. They’re tough to get rid of with just any filter. For these, we often need special carbon filters or a reverse osmosis system.

The reason a test is so important here is that these chemicals aren’t everywhere. A test at your home tells us if you need these special filters or an RO system for your drinking water. If they are there, we can set you up with a system that protects your whole house and a special filter for your drinking water.

A smart test helps us choose the right filters to keep your water safe without slowing down your water flow or making maintenance a headache.

How Can a Free Water Test Show You Your Home’s Water Problems?

Our free in-home water test is super helpful. We check things like how hard your water is, if there’s chlorine, the water’s pH, and if there’s dirt or iron. We can even check for PFAS and other VOCs if needed. We do some quick tests right there and can send samples to a lab for the tricky stuff. The results tell us exactly what kind of system you need.

For example, if your water is very hard, we’ll know what size softener you need. If you have chlorine, we’ll pick the right filter. This test takes away all the guesswork. It makes sure you get a system that fixes your actual water problems, not just what someone thinks you have.

After our test, you’ll feel confident choosing the right system – whether it’s a softener, a whole-house filter, or an RO system – to protect your plumbing and make your drinking water safe. Here at McCowin Water, Inc., we’re happy to offer you a free, no-strings-attached water test to find out what’s in your water and suggest the best solution just for you.

Your Water, Our Expertise.

Let’s get started with your free, personalized water analysis.

Why a Whole-House Water Filter is Great for Your Orange County Home

A whole-house filter, sometimes called a “point-of-entry” system, cleans all the water that comes into your home. It’s like a bodyguard for your water! It first takes out dirt, then uses special carbon to get rid of chlorine and bad tastes, and can even have extra filters for things like PFAS if you need them. This means cleaner water for your showers, your appliances, and all your plumbing.

You’ll notice less scale buildup (especially if you combine it with a softener), better laundry and dishes, softer skin and hair, and your appliances will last longer. We’ll help you pick a system that cleans your water without slowing down your water pressure.

Whole-house filters make a real difference throughout your entire home. When you’re thinking about one, we’ll help you consider how often you’ll change filters and what kind of flow you need. Here at McCowin Water, Inc., we’ve been installing whole-house filters all over Orange County, from Westminster to Orange, for a long time. We always start with a free in-home water test to make sure we pick the perfect filters for what’s in your water.

Different filters target different problems. This table helps you see what each one does:

Filter TypeWhat it Cleans / TargetsHow it Affects Water Flow & Upkeep
Regular Carbon FilterChlorine, bad tastes/smells, some chemicalsGood flow; change filter every 6–12 months
Special Catalytic CarbonChloramines (the tougher chlorine), more chemicalsNeeds a bigger filter; lasts longer but costs a bit more at first
Dirt Filter (Sediment)Sand, rust, tiny bits of stuffProtects other filters; cheap to change often
Special PFAS FilterSpecific PFAS chemicalsDesigned for tiny amounts; might need lab checks sometimes

How Do Different Whole-House Filters Clean Out Chlorine, Dirt, and PFAS?

Our whole-house systems use a few steps to clean your water. First, a dirt filter catches all the big stuff. Then, a carbon filter grabs the chlorine and other chemicals that make your water taste and smell bad. If you need it, special PFAS filters have tiny surfaces that trap those tricky chemicals.

The dirt filters keep the other filters from getting clogged, and the carbon filters make your water taste great. We make sure the system is sized right so you get clean water without losing water pressure. We’ll also show you how to keep it running well, like changing filters on time.

Picking the right filters means matching them to what’s in your water. That’s why our test is so important!

What’s it Like to Install a Whole-House Filter System?

When we install a whole-house filter, we first look at your home. We check your water pressure, where your main water line comes in, and how your pipes are set up. Then, we plan where to put the filters so they work best and are easy to get to for upkeep. We’ll turn off your main water for a bit, put in the filter tanks, connect them to your pipes (with bypass valves so we can work on them later), and then test everything to make sure there are no leaks.

We’ll also flush the system to get it ready. Most standard systems are installed in about a day. Bigger systems or adding a softener might take a bit longer. We’ll show you how to change filters and check the pressure. We promise to keep you in the loop so there are no surprises!

Good communication from the start means no surprises and a system that works perfectly for you.

How Often Do You Need to Change Filters in Whole-House Systems?

How often you change filters depends on the type. Dirt filters might need changing every 3 to 12 months, depending on how much dirt is in your water. Regular carbon filters usually last 6 to 12 months for most Orange County homes. Special PFAS filters have their own schedule, sometimes lasting over a year.

You’ll know it’s time when your water pressure drops, you start smelling chlorine again, your water looks cloudy, or you see dirt. We’ll show you how to watch your pressure gauges to help you know when. Regular check-ups from us can also make your filters last longer and keep your water clean. A simple routine keeps your system working great!

Keeping up with maintenance means fewer emergency repairs and better care for all your home’s appliances.

Let’s find the perfect whole-house solution for you.

How Water Softeners Fix Hard Water Problems in Irvine and Beyond

A water softener is a real game-changer for hard water. It works by swapping out those hard minerals like calcium and magnesium for something harmless, usually a tiny bit of sodium or potassium. This happens inside a tank filled with special beads. When the beads get full of hard minerals, the system cleans itself using a salt solution from another tank.

The big win for you? No more crusty scale, your appliances last longer, and your soap works so much better! We’ll help you pick the right size softener based on how hard your water is and how much water your family uses. We’ll also help you choose one that saves on salt and works best for you.

Picking the right system means knowing your water’s hardness and how much water you use. That’s why a free in-home test and our expert advice are so important before you buy. McCowin Water, Inc. gives you a custom plan, including a free test, to make sure your system is perfectly sized and runs just right.

Softener TypeHow it WorksGood ThingsThings to Consider
Salt-Based SoftenerSwaps hard minerals for sodium/potassiumReally gets rid of hardness; works greatNeeds salt, cleans itself with salty water going down the drain
Salt-Free ConditionerChanges minerals so they don’t stickEasy to care for, no salt neededDoesn’t remove hardness; just helps stop scale
Hybrid SystemsMixes softening with filteringOffers a bit of both, depending on how it’s set upCan be more complex and cost more at first

What is Ion Exchange and How Does it Get Rid of Hard Minerals?

Ion exchange is the fancy name for how a water softener works. Water flows through special beads that have sodium or potassium on them. When hard minerals (calcium, magnesium) touch these beads, they stick to the beads, and the beads let go of their sodium or potassium. So, your water comes out soft!

Over time, the beads get full of hard minerals. That’s when the system uses a salty water solution (from the brine tank) to clean the beads and get them ready to soften again. This process really makes your water much softer, often bringing it down to almost zero hardness. Just remember, it adds a tiny bit of sodium to your water, and you’ll need to add salt to the tank now and then.

Knowing how it works helps you understand why it’s so good at making your water soft and what you need to do to keep it running.

Salt-Based vs. Salt-Free Water Softeners: What’s Best for You?

Salt-based softeners are champions at making water truly soft. They make your soap work better and stop scale buildup completely. The trade-off is you need to buy salt and the system flushes salty water when it cleans itself.

Salt-free conditioners don’t remove the hard minerals, but they change them so they don’t stick and form scale. No salt, no salty water going down the drain! But they might not stop *all* scale if your water is super hard. Your choice might depend on local rules, how much upkeep you want, and how hard your water really is. If you have very hard water or fancy appliances, salt-based is usually the way to go. If you want super low maintenance, salt-free might be for you.

Our water test and expert advice will help you decide which type is perfect for your home, your appliances, and your cleaning needs.

How Do You Pick the Right Water Softener for Your Home?

Picking the right softener is easy with our help! First, we test your water to see how hard it is. Second, we figure out how much water your family uses each day. This helps us know how big your softener needs to be so it cleans itself at the right times.

We want to make sure it’s not too small (so it works well) and not too big (so you don’t pay for more than you need). We’ll also look at the quality of the softener and if you want a system that combines softening with whole-house filtration. Our experts will make sure the one you choose gives you soft water without wasting salt or lowering your water pressure.

Getting the right size means your system lasts longer and saves you money on energy and repairs.

Tips for Keeping Your Water Softener Running Great

Taking care of your softener is simple! Once a month, check the salt level in the tank. Make sure the salt isn’t stuck together in a “bridge.” Once a year, we can check the special beads inside and make sure the system is cleaning itself correctly.

To stop salt bridges, use good quality salt and break up any crusty layers. If your water starts feeling hard again or your water flow changes, check your salt, or give us a call. Regular service from us, including checking the pressure and cleaning the beads if needed, helps your softener last longer and work perfectly. A little care goes a long way!

A quick monthly check and a yearly visit from us mean your softener will work great, giving you peace of mind.

Tired of Hard Water Headaches?

Let’s get you the soft water you deserve, from Anaheim to Orange.

Why Reverse Osmosis (RO) is Your Best Bet for Pure Drinking Water in Orange County

Reverse osmosis, or RO, is like a super-filter for your drinking water. It pushes water through a very fine membrane that blocks almost everything dissolved in it – things like PFAS, heavy metals, and many chemicals.

First, other filters clean the water to protect this special membrane. Then, the RO membrane does its magic, making your water super pure. Finally, another filter makes sure it tastes great. The big benefits? You’ll drink much cleaner water, it tastes amazing, and it’s cheaper than buying bottled water all the time. We can put these systems right under your kitchen sink or wherever you get your drinking water.

RO systems need new filters and membranes now and then, and they usually have a tank to store your clean water. Sometimes, we can even add minerals back in for taste!

How Does Reverse Osmosis Make Your Drinking Water So Pure?

RO works by using pressure to push water through a super-tiny filter, called a membrane. This membrane has holes so small that only water molecules can get through, leaving behind all the bad stuff. Before the water hits this special membrane, other filters take out dirt and chlorine to keep the membrane safe.

Then, the RO membrane removes things like PFAS, heavy metals, and other dissolved stuff. Finally, a last filter makes sure your water tastes perfect. The RO process makes super clean water, but it also creates a little bit of wastewater. We make sure your system is set up to be as efficient as possible. Changing filters and the membrane on time keeps your water pure.

Understanding these steps helps you see why RO is the top choice for truly pure drinking water right from your tap.

What Are the Good Things About RO Systems for Your Health and Taste?

RO systems get rid of so many things that can affect your health and the taste of your water – like PFAS, lead, nitrates, and many chemicals. This means you’re drinking much safer water, and it tastes so much better than regular tap water. You won’t need to buy bottled water anymore, and your coffee, tea, and food will taste better too!

Since RO removes minerals, we can add a special filter to put back good minerals for a perfect taste. Over time, RO is much cheaper than buying bottled water, and changing filters is easy to keep track of.

If clean, safe drinking water is important to you, an RO system is a fantastic addition to your home, working great with whole-house filters and softeners.

How Do We Install and Take Care of an RO System in Your Home?

We usually install RO systems right under your kitchen sink, with a special faucet just for pure water. We connect it to your cold water line and add a storage tank that’s the right size for your family. Installation involves putting in the filters and membrane, connecting the tank, running the line to your new faucet, and checking for leaks. It usually takes just a few hours.

For upkeep, you’ll change the pre-filters every 6 to 12 months, the RO membrane every 2 to 5 years (depending on your water), and the final taste filter once a year. We’ll show you how to keep an eye on your water quality and pressure, and we’re always here if you notice any changes.

Regular care keeps your RO system working perfectly and makes the membrane last a long time.

How Much Does a Water System Cost in Orange County?

The cost of installing a water softener or filter system can change a lot. It depends on what kind of system you need, how big it is, what special filters it uses, and if we need to do any extra plumbing work in your home. Systems with special filters for things like PFAS or bigger multi-stage systems might cost more upfront.

But remember, the real value comes from getting the right system for your water, not just the most expensive one. To get a clear price, we need to know a few things: how hard your water is, how much water your family uses, your water pressure, and where you want the system installed. We believe in giving you honest, clear prices.

The table below shows you some common systems, what they might cost (including installation), and what makes the price go up or down.

System TypeTypical Price (System + Install)What Changes the Price
Basic Whole-House Filter (Dirt + Carbon)$2,000 – $5,000+Size of filters, type of filters, how much work to install
Whole-House with Special PFAS Filter$3,900 – $10,000+Cost of special filters, size of filter bed, testing needed
Salt-Based Water Softener (Home)$3,990 – $10,000+Size of softener, type of controls, plumbing work needed
Working Under-Sink RO System$1,500 – $2,500+Quality of membrane, size of tank, how hard the faucet install is

What Makes the Price of Whole-House Filters and Softeners Change?

A few things can change the price. It depends on the type of system and how big it is, if you need special filters (like for PFAS), if we need to change your plumbing or add bypass valves, and any local rules or permits. Sometimes, we might need to add something to control water pressure, or if space is tight, we might need custom parts.

The type of control on a softener also affects how much salt and water it uses. And don’t forget about the ongoing costs like changing filters and yearly service. If you have your water test results and some details about your plumbing before you get quotes, you’ll get much clearer and easier-to-compare prices.

Having a checklist of what we need helps you get accurate prices from us.

How to Keep Your Water System Running Great for Years

Keeping your water system in top shape means doing a few simple things regularly. This helps your system keep cleaning your water well and prevents problems. Each month, check the salt in your softener, look at the pressure gauges on your whole-house filters, and change filters on your RO and whole-house systems when the time comes.

Once a year, we recommend a professional check-up where we look at the softener beads, check the pressure, and make sure everything is working perfectly. You’ll know it’s time for service if your water flow slows down, you start seeing scale or smelling chlorine again, or your water looks cloudy.

Fixing these things quickly stops bigger problems from happening. A simple plan of homeowner tasks and our yearly check-ups means you’ll always have great water and fewer unexpected costs.

Here’s a simple checklist to help you:

  • Every Month: Check salt levels, look at pressure gauges, and visually inspect tanks and filter housings.
  • Every 6–12 Months: Change dirt and carbon pre-filters; we can re-test your water for key things.
  • Every Year: Get a professional check-up from us for calibration, softener bead assessment, and a full system performance check.

Regular care keeps your system working perfectly and makes it last longer, saving you from emergency repairs and keeping your plumbing and drinking water protected.

How Do You Know When to Change Filters or Replace Your Softener?

There are clear signs! If your water pressure drops a lot, you start seeing scale or soap scum again, you smell or taste chlorine, or your water looks cloudy, it’s probably time. Testing your water after maintenance helps confirm if a change is needed. Our service records also help us predict when things are due.

If fixing something costs almost as much as getting a new one, a new system is often the smarter choice. Acting fast prevents damage to your appliances and keeps your water clean.

Keeping track of how your system is performing helps you make smart decisions about when to replace things.

How to Manage Salt and Keep Your Softener Working Perfectly

Keeping your softener happy means always having enough salt in the tank. Make sure the salt isn’t stuck together in a “bridge” by using good quality salt and breaking up any crusty layers. We’ll also make sure your softener is set to clean itself at the right times for your family’s water use, so you don’t waste salt or water.

Monthly checks and our yearly professional calibration keep your softener beads healthy and your water soft. If your water stays hard after the softener cleans itself, it’s time to call us.

Doing your part and having us check things yearly means consistent soft water and efficient salt use.

What Are the Benefits of Regular Professional Service from McCowin Water?

When McCowin Water takes care of your system, you get the best performance because we make sure everything is set just right. Your equipment lasts longer because we do preventative care, and you’ll have clear records for warranties or if you ever sell your home.

Preventative maintenance means fewer emergency repairs and helps us spot problems early, like dirty softener beads, which can stop costly appliance damage. For example, our scheduled service can catch a problem with your softener before it causes your water heater to break down. Professional service also gives you peace of mind, knowing experts are there to help and replace parts when needed.

Our long-term support means your system will be reliable and save you money over its lifetime.

You’re Not Just Tired of Hard Water. You’re Tired of the Runaround.

Most Systems Sell Simplicity. We Deliver Protection.

I’ve been doing this for decades. And I can tell you, most systems aren’t built wrong.
They’re sold wrong.

They don’t test your pressure. They don’t check your copper. They give you the same setup they give everyone else.

At McCowin Water, we slow it down, test your actual water, and build a system matched to your house, your pressure, and your needs.


 

What You’re Probably Dealing With (And No One Told You)

  • Pinhole copper leaks from chlorine that’s never removed
  • Scale buildup torching your heater, dishwasher, and fixtures
  • Dry skin and flare-ups from chloramines and hard minerals
  • Bottled water habits because you still don’t trust your tap

If that sounds familiar, you’re not crazy. You’re just ready for clarity.


 

What We Actually Do

  • Reverse Osmosis + Whole-Home Filtration
  • No sodium sludge, no cookie-cutter kits
  • Real installs done by certified techs, not sales guys
  • Systems built for longevity, not callbacks
  • Every install starts with a free, in-home test

We’re not trying to sell you something.
We’re here to protect your plumbing, your people, and your peace of mind.


 

Here’s What You’ll Get With Us:

  • Real conversation, not a pitch
  • The same system I use in my own home
  • Custom-calibrated setup for your PSI and contaminant profile
  • Under-sink RO if needed; installed clean and tested before we leave

Up to 25-year warranty, registered by us before you even ask

Follow-up call to confirm: no leaks, no issues, no nonsense

We’ve been doing this since 1972. And the truth hasn’t changed:
