Why Mixer Taps Fail (And How to Fix or Replace Them in Birmingham)
Mixer taps are a popular choice in modern homes across Birmingham, but like all plumbing fixtures, they can develop faults over time. One of the most common reasons for mixer tap problems is the ceramic disc cartridge inside the tap.
In this blog, we’ll explain why mixer taps fail, how disc cartridges work, what makes repairs difficult, and when it may be better to replace the tap altogether. We’ll also cover the average cost of replacing a tap in Birmingham and the best tap brands for long-term reliability.
How Mixer Taps Work
Unlike old-style washer taps, most modern mixer taps use ceramic disc cartridges. These cartridges control the flow and mix of hot and cold water with a smooth, quarter-turn action.
They are designed to be durable, but over time they can wear out, especially in areas like Birmingham where limescale can build up inside the cartridge.
Why Mixer Tap Disc Cartridges Fail
There are several reasons why your mixer tap might stop working properly:
1. Limescale Buildup
Hard water in Birmingham leads to limescale deposits. These deposits can block the cartridge, making the tap stiff or preventing water from flowing smoothly.
2. Worn Ceramic Discs
Over years of use, the ceramic discs inside the cartridge can wear out. Once they stop sealing correctly, you’ll notice dripping taps or difficulty controlling the temperature.
3. Cheap or Non-Standard Cartridges
Not all mixer taps use the same size or style of cartridge. Many cheaper brands use non-standard parts, which makes it very difficult to track down the correct replacement.
Why It’s Hard to Find the Right Cartridge
One of the biggest frustrations for homeowners (and even plumbers) is that cartridges are not universal. There are hundreds of different sizes and designs, often specific to the brand and even the exact model of tap.
This means:
- It can take a lot of time to identify the correct cartridge.
- Parts may need to be ordered from abroad.
- Some cartridges are discontinued, making repairs impossible.
Because of this, many Birmingham plumbers (including us at Afterglow Heating) will often recommend replacing the entire tap instead of attempting a cartridge repair.
When Replacing the Tap Is the Better Option
If your mixer tap is leaking or difficult to use, replacing the cartridge may sound like the cheaper option. But in many cases, replacing the entire tap is more cost-effective.
Reasons to replace the tap include:
- Difficulty sourcing the correct cartridge.
- High cost of specialist cartridges compared to a new tap.
- Upgrading to a modern, water-efficient tap.
- Peace of mind with a fresh manufacturer’s warranty.
