2 Reasons for The Hansgrohe Shower Valve Leaking

Below are two reasons why your shower valve is leaking:

1. Defective Shower Valve Cartridge

A shower cartridge located inside the shower valve controls water temperature and volume. It looks like a small shower valve and protrudes typically from the shower valve while connecting to the exterior handle.

The cartridge is usually made of plastic, which wears or cracks over time, and when it does, it lets water seep through it even when the shower water is turned off. 

In this case, you will hear a trickling sound coming from your shower head when no one is using the shower. 


If the problem is a defective shower cartridge, the solution is to change it. Get a quality Hansgrohe shower valve cartridge and fix it there.

How do I change a Hansgrohe shower cartridge?

Here’s how to replace the Hansgrohe shower cartridge:

The Tools

  • A replacement shower cartridge
  • The right size spanner
  • Pair of pliers

The Steps

  • Turn off your shower water off
  • Locate the screws that hold the shower handle to the wall and unscrew them slowly
  • Once you remove the shower handle, you can now access the shower cartridge
  • Loosen the nuts that hold the shower cartridge into position
  • Pull the shower cartridge out using a pair of pliers
  • Slide in the new Hansgrohe cartridge and fasten it into position
  • Put the handle back and turn on the water to see if the leaking has stopped

2. Worn Out Shower valve

If the shower valve continues to leak after replacing the shower cartridge, it means that your Hansgrohe shower valve could be faulty.  

Remember, the Hansgrohe shower valve sits behind the shower faucet. Its job is to direct cold and hot water to your showerhead. 

Over time, a shower valve may become clogged with mineral deposits or get damaged. If that happens, its effectiveness reduces, and one way it shows for it is through the leakage.


If the issue is a faulty or worn-out Hansgrohe shower valve, its fix is finding a replacement.

Remember, however, that though many Hansgrohe shower valves have the same fitting, it’s always a good idea to confirm the size to get the perfect fit.

How Do You Fix a Leaky Hansgrohe Shower?

There are different reasons why the Hansgrohe shower may leak. Two are those we’ve discussed; shower valve and calve cartridge. The other, however, is the showerhead. 

If your Hansgrohe shower continues to leak after changing the shower valve or the shower cartridge, you should check the showerhead. The chances are that it might be faulty or just worn out and needs replacing.

Cause and Fix

Often, the Hansgrohe showerhead starts to leak if it is clogged with grime or dirt. If that’s the case, you should consider washing it first, which you can do with vinegar solution and a regular toothbrush.  However, be careful not to damage the thread nozzles.

How about a faulty showerhead?

Inside the showerhead is an O-ring or rubber washer that seals the shower hose and the showerhead to prevent water leakage.

Over time, the rubber or O-ring may wear out, making water leak through your shower head. If you are dealing with a worn-out rubber washer or O-ring, you can replace it.

But, if, after all, nothing seems to correct the water leakage, it’s now time to replace your shower head.

You can do it by simply following the steps below:

The Tools 

You’ll need these two tools:

  • Replacement shower head
  • screwdriver

The Steps

Here are the steps to follow:

  • Turn your bathroom water supply off
  • Remove the old showerhead and replace it with the new one
  • Turn on your shower water supply and check if there are notable leaks
  • If not, congrats! You installed the new showerhead correctly
