❓What Are Inline Water Filters?
Inline filters are small, self-contained cartridges installed directly into your water line. They’re a space-saving alternative to traditional filter housings and provide excellent filtration at a lower capital cost. These filters are perfect for tight spaces and systems where simplicity and reliability are essential.

Questions of Inline Water Filters
Do Inline Water Filters Reduce Pressure?
Yes, inline water filters can reduce water pressure slightly, but this is usually minimal if the filter is properly matched to your system. A pressure drop can occur as water passes through the filter media—especially if the filter is clogged, undersized, or nearing the end of its service life.
To minimise pressure loss, it’s important to:
Choose a filter with an appropriate flow rate for your application
Replace cartridges regularly as per manufacturer guidelines
Ensure proper installation using compatible fittings and pipe sizes
At Wrekin Water, our inline filters are selected for both performance and efficiency, helping you maintain good flow while delivering cleaner water.
How long do inline water filters last?
Most inline water filters last between 6 to 12 months, depending on several factors:
Water quality – Higher levels of sediment, chlorine, or hardness may reduce lifespan
Water usage – The more water that passes through the filter, the faster it will reach capacity
Filter type – Granular activated carbon (GAC) and carbon block filters may have different capacities
Application – Filters used for fridges or coffee machines may last longer than those used for whole-house pre-treatment
At Wrekin Water, we recommend checking the manufacturer's guidelines for your specific filter model and replacing it at least once a year or sooner if there’s a noticeable drop in flow or water quality.

What happens if you overuse a water filter?
Overusing a water filter—by continuing to use it past its recommended lifespan—can lead to several problems:
🚱 Decreased Filtration Performance
The filter media becomes saturated over time, meaning it can no longer effectively remove contaminants like chlorine, sediment, or taste/odour compounds.
💧 Reduced Water Flow
As the filter clogs with trapped particles, water flow slows down, potentially affecting the performance of appliances like coffee machines, fridges, or water coolers.
⚠️ Bacterial Growth
In some cases, old filters can become a breeding ground for bacteria, especially if left unused for extended periods while wet.
❌ Risk of Recontamination
Instead of removing contaminants, an exhausted filter might start leaching what it previously captured back into the water—leading to poorer water quality than before.
At Wrekin Water, we always recommend replacing inline water filters on time to ensure safe, clean water and protect your system. Most filters should be changed every 6–12 months, depending on use and water quality.
Can I Replace An Inline Filter Myself?
Yes, in most cases, you can change an inline water filter yourself—and it's usually quick and straightforward.
✅ What You’ll Need:
A new compatible inline filter
Access to shut off the water supply
Possibly a wrench or spanner (depending on fittings)
A towel or small container for any water drips
🔄 Basic Steps:
Turn off the water supply
Release any pressure by opening a nearby tap
Disconnect the old filter (push-fit, spigot, or threaded connections)
Install the new filter, ensuring arrows on the cartridge match the flow direction
Turn water back on and check for leaks
Flush the filter (typically 5–10 minutes) to remove any carbon dust or air
⚠️ Tips:
Always follow the manufacturer’s installation guide
Make sure the fittings match (¼", ⅜", or ¾")
If you're unsure or it’s part of a complex system, call a professional
