First off I want everyone to know that this fix will only work on an Australian toilet as I have no idea whether modifications have been made to exported models to comply with overseas specifications. So, if you have a Caroma Dual Flush toilet that was made between 1981 and 2000 that leaks, then this should work for you.

It’s very important that you fix the leak because apart from being very wasteful it’s also costing you  money. There are two causes of leaks in your toilet, one being the seating washer and the second being the head seal ballcock washer and this solution fixes the second one. You know you need to replace the ballcock washer when the water rises to the extent that it rises over the overflow tube.

First thing you need to do is remove the cover from the cistern by lifting it off. You know you’re on the right track if what you see resembles this photo.


If your loo looks like the one in the photo you can proceed with the next step which is to turn off the tap located on the wall somewhere below the cistern otherwise you’re going to have water pissing out everywhere. Once you’ve done that flush the toilet and then you need to pull out the little metal pin.


Use a pair of pliers if you can’t do it manually. Your next step is to lift the float arm off it’s cradle and then to lift the plastic locking ring. You may have to pry the pointy section on the left from it’s seating.


From there you simply screw off the plastic cap and remove it which will reveal the following.


Now that little gizmo that you see there is what holds your head seal, red rubber washer, and your ballcock which is the smaller black rubber. You can buy the new parts at any reputable hardware store. You simply replace the old ones with the new and then follow all the steps in reverse. Once you’ve done all that simply turn the tap on again and you should be good to go.
