Why Is Your Hansgrohe Raindance Valve Leaking?
A leaking valve on your Hansgrohe Raindance shower from 2018 might be caused by a degraded cartridge, loose fittings, or limescale buildup affecting the seal. After years of use, these issues creep up, but you can fix the drip with some effort. Here’s a detailed repair guide.
Tools You’ll Need
- Adjustable wrench
- Phillips screwdriver
- Replacement cartridge (Hansgrohe #92730000)
- Plumber’s tape (Teflon)
- Vinegar and brush
Step 1: Shut Off the Water
Prevent a flood.
- Locate the main water shut-off valve (usually under the sink or in the basement).
- Turn it clockwise until fully closed, then test the shower.
Step 2: Remove the Valve Handle
Get inside the mechanism.
- Find the small screw under the Raindance handle (often hidden under a cap).
- Use a Phillips screwdriver to remove it, then pull the handle off gently.
- Set it aside carefully.
Step 3: Replace the Cartridge
The cartridge is often the leak source.
- Unscrew the retaining nut with a wrench (turn counterclockwise).
- Pull out the old cartridge—note its orientation.
- Insert the new Hansgrohe cartridge, aligning it properly, and tighten the nut.
Step 4: Clean Limescale
Buildup can weaken seals.
- Soak the valve area in vinegar for 15 minutes using a cloth or bag.
- Scrub with a brush to remove deposits, then rinse.
- Check seals—if cracked, replace with new O-rings.
Step 5: Reassemble and Test
Finish the job.
- Wrap plumber’s tape around threaded parts for a tight seal.
- Reattach the handle, screw it in, and turn the water back on.
- Run the shower—if no drip, you’ve fixed it!
Your Raindance valve should now be leak-free. For low pressure, see this guide. For limescale issues, check this fix.
