Ideal Standard e752 cistern won't stop running

[Azatha]

My toilet will not stop running water into the bowl after flushing! The only way to make it stop is to turn the water off completely. I've tried raising the float, but that doesn't do anything. I've got two in my house and now they are both doing this and it's driving me mad! Help! I've attached a picture of the inside, as most pictures I find online do not seem to be the same toilet type.

This is a common issue with push button "water saving" toilets. They rely on an inferior design to the traditional syphon "handle" flush.

The parts wear quicker and hence leak water constantly down the toilet. Resulting in much more wasted water!

Needless to say it requires a replacement of the valve flap. You are probably best replacing the whole of the valve unit. Parts should be available at B&Q or online.

I see. Which part is the valve flap? I have no idea what I'm doing.

Look at the pictures on that website link I gave you.

The valve in this case is that big central pillar in your toilet cistern. The flap is a piece of rubber at the bottom which acts like a plug to stop the water draining constantly. It has obviously begun to fail.

Look on youtube for "replacing toilet valve".

Should be quite simple.

That website link explains it in much more detail.
