Geberit Toilet Parts: Identifying your ceramic cistern Geberit parts

This is the second part of our 2 part information article about Geberit spare parts. If you need information on how to identify what spare part you need for in-wall cisterns, please click here

If not read on!

This article is based on identifying the correct spare part for external cisterns which are your more traditional toilet where you can see the cistern and the Geberit spare parts will be enclosed within the ceramic cistern. The key point about geberit is they don’t make the ceramic components of the toilet, they are the parts that are the internal working mechanisms for Companies such as Villeroy & Boch, Duravit, Caroma, RAK and Parisi.

How do I know that my exposed cistern has Geberit parts?

The first way to identify a Geberit cistern is by looking at what button you have on top of the ceramic cistern. Your toilet is likely to be a Villeroy & Boch, Duravit, Caroma, RAK or Parisi brand toilet. The two types of buttons from Geberit look like this (note they may not say Geberit on the button as you will see below

Once you have identified that you have one of these styles of button, you will then need to remove the button.

Geberit Dual Flush typ 250 Button Cisterns

If your button looks like the above then you have a typ 250 cistern which has a series of spare parts. To remove your button so you can remove the lid, you will see a little indent on the inside of either of those two buttons that is for a small flat head screw driver to pop up the button. Once one is off, the other will easily come off. You’ll then see a screw which is usually white and unscrew that to lift of the cistern lid. Now you should be able to see into the cistern to identify the issue

What if my toilet is hard to flush or when I push the buttons down it doesn’t seem to work?

This could be a few things but there are some easy ways to identify what it may be. First check that the green and black rods haven’t snapped. If they have, you need this component below

If your rods are in good condition and haven’t broken, you then need to check the cistern lid bracket which goes over and sits above the actual outlet valve. This product is shown below. In the middle of the top section is where the two rods slide through to hit the pads below on the outlet valve. Sometimes they can crack which means the rods can know longer be guided down to hit either the half or full flush. If that is the case, you only need to purchase the below product

This is the area I am talking about above where you can see the rods hit two pads separately (note yours may be green and black still)

What if all of these products are ok?

If that is the case, you need to press on the pads to see if it still flushes correctly. If it doesn’t flush correctly or continues to run into the toilet pan after flushing, you need to purchase either of the 3 products depending on how much of the cistern you want to replace. These 3 products are also the products you purchase if water continues to run into your toilet pan after flushing. The washer is the first one you replace as this is the easiest, if the flushing isn’t working properly and it is also leaking into the pan, it is best to replace the outlet valve as it comes with the washer (membrane). If you feel it could be the valve (cylinder part in the middle) or maybe the cistern lid bracket etc, you are best to replace the whole thing which is $96.00 and comes with the button, rods, cistern lid bracket, outlet valve and outlet valve washer

What if my cistern makes a hissing sound when flushing or overfills

It will be obvious if your cistern is making a hissing sound inside this ceramic cistern. You will also need to buy one of the below product if your cistern is over filling (you can tell this by watching it fill up and if it goes over the normal line it may be filling due to a faulty inlet valve). Sometimes you will only need to purchase the unifill valve and that can fix the problem. However, most of the time by replacing the intlet valve itself you will have a better chance of fixing the issue

What if my Inlet valve doesn’t look like this and doesn’t have a flexible hose?

This is a common question and is for older cistern models including the Typ 250 and the old typ 260 which is now the typ 290. If this is the part you require, buy the below product

If your button looks like the below read on

The important part about the buttons with these cisterns is that the outlet valve which connects to this button is not made anymore. Hence, if it is just that the button is broke (usually the white part at the bottom of it) then just replace this. Thus button simply unscrews so turn it and will be begin loosen up which will then allow you to remove the cistern lid. Your cistern from above will probably look like this:

The old typ 280

If your cistern is over filling or continues to run after flushing then read below

If this is happening, you can either simply try to replace the washer which is the clear rubber that sometimes gets worn and allows water to drip through. Otherwise, if it is difficult to flush and continues to run, replacing the outlet valve is the best solution. However, please note you will need to replace the entire outlet valve and the button which is also a below product and is the new model for the above older typ 280.

What is water is leaking between where the cistern and the actual toilet pan meet behind the seat.

This is a good question and you will need to replace the bolt kit and donut seal with the appropriate branded product which are both below

What if it is neither of these?

If it is neither, either send us photos to or you may have the Impuls260 outlet valve for close-coupled cisterns which can be found in some models of the following brands:
Kohler, Parisi, R.A.K. Villeroy and Boch, Vitra

It is recommended that every 5 years you replace your flexible inlet hose. If these burst, a lot of water will end up in your bathroom and possibly out through the door
