Signs Your Water Filtration System Isn’t Working Properly

Something about your water feels different lately. Maybe it’s the taste. Maybe it’s the way it looks when you fill a glass. Or maybe you can’t quite explain it… you just know it isn’t the same.

The question is, is it really your imagination, or is your water filtration system starting to fail? More importantly, how can you be sure before the problem gets worse?

There are certain clues most people miss until their water quality has already dropped. If you know what to watch for, you can catch the issue early and decide whether a water filtration repair is all you need or if it’s time to start thinking about a replacement.

Let’s take a closer look at the warning signs a plumber sees all the time.

1. When the Water Tastes Different

If you’ve been drinking your tap water for years, you know exactly how it should taste. The moment something changes, even slightly, it’s worth paying attention to. Sometimes it’s a metallic tang, other times it’s a strong chemical taste. Some people describe it as almost earthy or stale.

That change could be your filtration system no longer removing certain minerals or chemicals. A clogged or worn-out filter lets more of those elements pass through. The longer it goes unchecked, the more likely it is that you’ll need more than a simple repair.

This is one of those times when calling in a plumber right away makes sense. We can test the water, check the system, and let you know if a repair will get things back to normal or if a new filter setup is the safer move.

2. Changes in Smell

Water shouldn’t have much of a smell at all. If you notice an odor—whether it’s chlorine, sulfur, or something musty – it’s a sign the filtration system isn’t catching certain contaminants.

We’ve walked into homes where the smell was barely noticeable at first, but over time it became stronger. In every case, the filter wasn’t doing its job anymore. Sometimes it’s just a matter of replacing a worn filter cartridge. Other times, the entire filtration unit needs to be replaced because it’s no longer effective.

A water filtration repair can be quick and affordable if you catch it early. Waiting too long can make replacement your only option.

3. Cloudy or Discolored Water

Clear water is non-negotiable. If your water looks cloudy or has a tint to it, that’s a sign that something is making its way past the filter. Sediment, rust, and mineral buildup are all possible culprits.

We’ve seen this happen in homes where the filter was left unchanged for too long, and in systems that were simply too old to keep up. Cloudy water isn’t just about appearance—it can point to bigger plumbing issues if the source is within your pipes.

When we inspect a system with this issue, we not only check the filter but also the plumbing that brings water into your home. That way you know exactly where the problem is coming from before deciding on repair or replacement.

4. Drop in Water Pressure

If you’ve noticed it takes longer to fill a pot or your shower pressure has dipped, your filtration system might be part of the problem. When filters become clogged with debris, they can choke the water flow.

The tricky part is that low pressure can also come from other plumbing issues, so it’s not always the filter’s fault. That’s why it’s important to have a plumber check the system as part of the diagnosis. If the filter is the cause, we’ll let you know whether a quick cleaning or filter change will fix it, or if the system itself is past its prime.

5. Health Changes in the Household

It’s not something most people connect right away, but if you or your family start having unexplained stomach problems, skin irritation, or other health symptoms, it could be linked to water quality. If the filtration system isn’t blocking contaminants like bacteria or heavy metals, those can end up in your drinking and cooking water.

We always recommend testing your water in these situations. Once we know what’s in it, we can make a plan. Sometimes it’s a repair. Other times, especially if the system is old or damaged, replacement is the safest choice.

Repair or Replace?

A water filtration repair makes sense if the problem is limited to worn seals, clogged filters, or a faulty valve. Those fixes are straightforward and affordable. But if the system is leaking, corroded, or more than a decade old, a water filtration replacement is usually the better long-term investment.

When we visit a home, we always start with an honest assessment. Our goal is to make sure you’re not spending money where you don’t have to, but also not holding onto a system that can’t give you the clean water your home needs.

Don’t Wait Until the Problem Gets Worse

Water filtration is one of those things you don’t notice until it’s not working. By the time the signs are obvious, you may already be dealing with water that isn’t safe or pleasant to drink.

If you’ve spotted any of these changes or even if you’re just suspicious that something’s not right, call Acacias Plumbing. We can inspect your water filtration system, run quality tests, and guide you on whether a repair will do the job or if replacement is the smarter option.

Clean water is worth acting on quickly. Waiting will only give the problem more time to grow.
