Water Filtration System Installation

When it comes to water filtration system installation, it’s not a one-size-fits-all deal. Every home is unique, just like its water. That’s why we start by getting to know your water supply and what you’re hoping to fix. Whether you’re dealing with hard water, chlorine taste, or other contaminants, we tailor each installation to meet your needs.

We serve all across Ontario, CA, and the greater Inland Empire, offering expert installation and real-deal experience. No guesswork, just dependable systems set up right the first time. And we make sure you understand how it works before we leave. From whole-house filtration to point-of-use filters, we do it all—and we do it well.

Water Filtration Systems We Install

There are a lot of options out there, and not all of them are created equal. Here at All Pro, we only recommend systems that we trust—the ones we’d put in our own homes. Our range of water treatment systems is designed to fit your needs and your budget. Let’s take a closer look.

Reverse Osmosis Systems

Reverse osmosis systems (or RO systems) are a game-changer for drinking water. These powerful systems use multiple stages of filtration to remove contaminants like lead, arsenic, fluoride, and even some viruses and bacteria. What you’re left with is water that tastes fresh and pure—the kind you actually want to drink straight from the tap.

A reverse osmosis system usually sits under your kitchen sink and uses reverse osmosis filters to push water through a semi-permeable membrane. That membrane acts like a microscopic net, trapping the bad stuff while letting clean water through. It’s ideal for families who want the best water at the source they use most.

Our team installs these systems with precision, making sure they integrate smoothly with your plumbing. And we’re happy to help you maintain them over time, replacing filters and checking for issues.

Activated Carbon Filters

If your tap water smells like a swimming pool or tastes a little off, an activated carbon filter might be your new best friend. These filters work by absorbing chlorine, volatile organic compounds (VOCs), and other chemical contaminants. They’re great for improving both taste and odor without breaking the bank.

Activated carbon filters can be part of a whole-house system or a smaller setup just for your kitchen. Either way, they deliver immediate results. They’re one of the most popular choices for water filtration in Ontario, and for good reason—they work.

UV Filters

When you’re worried about microorganisms in your water—things like bacteria, viruses, or parasites—UV filters offer a high-tech solution. These systems use ultraviolet light to destroy the DNA of harmful pathogens, effectively sterilizing your water without adding any chemicals.

UV filtration is often used in tandem with other systems (like reverse osmosis or carbon filters) to create a comprehensive barrier against all sorts of contaminants. It’s especially useful if you have private well water or are concerned about waterborne illnesses.

We Also Install Water Softeners

Hard water is a common issue in Ontario, CA, and it can cause all kinds of problems—from dry skin and dull hair to limescale in your pipes and appliances. A water softener changes that by removing excess calcium and magnesium from your water. These systems can make a huge difference. At All Pro, we install a variety of high-performance water softeners designed to tackle hard water and keep your home running smoothly. Say goodbye to hard water buildup and hello to brighter laundry, cleaner dishes, and happier skin.

The Most Common Issues With Water Filtration Systems

Water filtration systems are fantastic, but like anything else, they can hit a few snags. Whether you’re using a simple under-sink unit or a complex whole-house setup, wear and tear is inevitable. The good news? Most problems are easily fixable—especially with a team like ours. Here are the issues we run into most often and what they mean for your water quality and home.

• Clogged filters: Filters do the heavy lifting by trapping sediment, chlorine, bacteria, and other contaminants. Over time, all that buildup starts to clog things up, which can reduce water pressure or even stop filtration altogether. If your water starts tasting off or your flow slows to a trickle, it might be time to swap in a fresh filter. It’s a small fix that makes a huge difference—and one of the most common issues we solve for Ontario residents.
• Leaks: Leaks can pop up anywhere—in hoses, seals, fittings, or even the filter housing itself. They might start as a slow drip under the sink or a small puddle near your unit, but they can quickly escalate into bigger plumbing issues if ignored. Hard water can speed up the wear on rubber gaskets and fittings, so regular inspections go a long way. If you spot water where it shouldn’t be, don’t wait. Give us a call.
• Bad taste or odor returns: If your water suddenly tastes metallic or smells like chlorine again, your system might not be filtering properly. This could mean your filter is past its prime, or that new contaminants have entered your water supply due to changes in your municipal system or recent plumbing work. Sometimes, the issue lies deeper within the filtration system, such as a compromised membrane or an improperly functioning carbon filter. Either way, we can test your water and get to the root of the problem.
• System not turning on: Some advanced filtration units, especially reverse osmosis and UV systems, rely on electrical components to operate. If your system isn’t turning on, the issue might be as simple as a tripped circuit or blown fuse. Other times, it could be a faulty control panel or disconnected wiring. We’ll troubleshoot it efficiently, and in most cases, we can fix it during the same visit.
• Low flow rate: Not getting enough water? A sluggish flow rate can be frustrating, especially when you’re used to a quick fill. This is especially common in RO systems, where the storage tank or filters might be the culprit. A clogged membrane, pressurized tank issues, or even incorrect filter installation can all lead to slow water delivery. We check everything to get your system flowing freely again.

We handle all of these issues and more, using a mix of experience, precision tools, and good old-fashioned know-how. If your system’s been giving you trouble, just reach out. We’re happy to help.
