Is your Geberit wall-hung toilet having trouble flushing into your bowl?

Hello, it's Stan!
If your toilet bowl flushes poorly, that is to say that the force of the flush is not powerful enough to properly flush everything into the bowl... It is because your bowl has a blocked water passage, like a bottleneck.
Let me explain, this problem can come from two things:

Either your toilet has a pebble, which has a filter clogged with limescale/mold




It is removed by gently pulling it while making small clockwise rotations, from right to left. If the filter is dirty, the problem comes from there… Simply clean it and put it back in place.

Either your toilet bowl is clogged with limescale from the inside.
If you don't have a pebble, you'll have to remove the toilet bowl to clean it from the inside. Don't worry, it's easy to do. Follow my steps:

Turn off the water supply!
Turn off the water supply using the small shutoff valve in your tank or at the main faucet, then flush the toilet to empty your tank. Automatically flushing the toilet without a bowl... I'll let you imagine!

1. Remove the bowl:
• Unscrew the two nuts located on the right and left of the bowl. These nuts are often hidden by caps. You will need a 19 mm open-end wrench or an adjustable wrench. (If you don't have one, I've included an open-end wrench in the articles, below this text.)
• Cut the silicone around the bowl using a cutter. (Sometimes there is no silicone.)
• Detach the toilet bowl from the wall.

2. Clean the pipes and the bowl:
• You will discover two pipes that connect the frame to the bowl. Remove them, clean them, discard their gaskets and keep them to one side.
• Now, reach into the back of the bowl and clean the limescale buildup in the water injection passage. This is where the blockage is, creating a bottleneck that reduces the flushing power.

3. Replace the 4 seals:
• When you replace the cuffs, it is important to change their Geberit seals.
• There are two gaskets installed on the sleeves (the ones you already removed) and two other gaskets installed on the frame side that need to be replaced. These gaskets are standard at Geberit. I created a kit with all 4 gaskets below this text. Replace them all to avoid leaks when reinstalling the toilet. The old gaskets are marked and may leak.

4. Lubrication and reinstallation:
• Apply Geberit lubricant to the inside of the seals to facilitate insertion of the sleeves on the frame side.
• Then gently place the bowl back against the wall and tighten the nuts.

These are basically the steps to solve the problem of low hunting power.
