Leaking & Sticking Issue With 2 Button Toilet Valve

nicenswift

Hi,

Hope everyone is well.

My 2 button valve (I have attached pictures) in my toilet is letting a trickle of water into the pan constantly (it has been doing this for a few weeks now)

In the last 3 days the valve seems to be randomly sticking open and water just flows straight into the pan and never fills the tank back up.

When it does his the buttons are not stuck down at all and the only way to cure it is to press both buttons a few times and it seems to free up and water stops running into the pan and starts filling the tank back up as normal.

I presume that to fix both the problems I need a new valve but cant seem to find one that matches mine (I have attached pictures)

If I can find one that matches I presume its a simple replacement job I could undertake myself (I am not very DIY savvy)

Many thanks for your time

It's not clear how the valve is operated by the buttons, but most likely you don't need the same and can replace it with any of the modern buttons-operated valves.

As you ask, I think you need a plumber or a handyman to chose and fit it.

You have a Geberit dual flush valve
Here is a video https://www.youtube.com/watch?v=EfgTNHULmTI showing how to dissemble and fix it.

If you need a new one they are very popular and widely available for less than £20, such as this:
