You install your new shower filter with high hopes, turn on the tap… and the water comes out weak. You wonder: is this normal? Did I do something wrong? Is the filter not compatible?
Don’t worry, you’re not the only one. A shower filter losing pressure can have several causes, and in most cases, it has a quick fix.
Here we explain why it happens and how to solve it step by step, so you can enjoy a comfortable and healthy shower.
Is It Normal for a Shower Filter to Reduce Water Pressure?
Yes and no. Some filters may slightly reduce the pressure, but they shouldn’t make the water come out in a trickle. If you notice a sharp drop, there’s probably a specific issue that can be corrected.
The Difference Between Lower Pressure and Efficient Filtration
It’s important to understand that:
- A little less pressure is normal if the filter is removing sediments, limescale, and chlorine.
- A shower with almost no flow indicates a blockage or malfunction.
- A good filter, like those from Tappwater, is designed to balance performance and flow, providing clean water without affecting your shower experience.
Main Causes of Pressure Loss After Installing a Filter
Let’s look at the most common ones:
Limescale or Sediment Buildup in the Filter
Over time, minerals in hard water can clog the cartridge or the filter’s internal connections.
Clogged or Dirty Showerhead
Even if you install a new filter, if the showerhead nozzle is full of limescale or debris, the water won’t flow properly. This is a common but often overlooked cause.
Incorrect Installation or Incompatible Filter
If the filter isn’t fitted properly, or if it isn’t compatible with your shower, it can restrict water flow or even cause leaks that affect pressure.
Expired or Saturated Cartridge
If you haven’t changed the cartridge in months, it’s likely saturated. A clogged cartridge won’t let water through as it should, causing drastic pressure loss.
How to Fix Pressure Loss Step by Step
Here’s a practical guide:
1. Clean and Check the Showerhead and Filter Assembly
- Remove the filter and showerhead.
- Clean them with diluted white vinegar if there’s limescale.
- Make sure the installation is tight, with no leaks or loose parts.
2. Test Without the Filter to Compare
Remove the filter temporarily and turn on the water. If the pressure goes back to normal, the issue is with the filter or cartridge.
3. Replace the Cartridge if It’s Old
If it’s been more than 3–6 months (depending on the model and usage), replace the cartridge. A saturated cartridge is the most common cause of low pressure.
Tips to Prevent Pressure Problems in the Future
Regular Maintenance of the Filter and Showerhead
Do a simple monthly cleaning. Just check the showerhead and disassemble the filter to remove any sediments.
Choose the Right Filter for Your Water Type
If you live in an area with very hard water, pick a filter designed to handle limescale, like the Tappwater ShowerPro Diamond. It’s built to maintain flow even with tough water.
Check the Manufacturer’s Recommended Flow Rate
Not all filters are made for high-pressure systems or designer showers. Read the specifications carefully and make sure the filter is compatible with your setup.
