My push button toilet keeps filling

[Monogram]

Hi all!

I've got a weird situation where after the toilet fills up after flushing, it'll keep trickling water out. Even though the float/shut off lever is all the way up.. Then if I go to a tap and give it a short burst on cold it shuts it off?! Anyone know what's going on here and how I could fix it?

Might be worth mentioning that when the shower is on in a different room this toilet makes the same trickling noise, until the shower stops and it cuts off.

Any advice would he much appreciated, I cant cope with standing by the bog ery time I flush it to make sure the water isn't constantly running!

Heres a vid of what happens..

Cheers,
Tom

The black top coloured valve is a Fluidmaster and is faulty.
A new Fluidmaster diaphragm washer might sort it, and just involves turning water off to cistern and giving the cap part a slight twist to remove to top and replace the washer.
But probably best to have entire valve replaced with a Fluidmaster Pro45B valve (it has brass tail) or a similar brand.

Ok great, thanks mate. Are they pretty straightforward for swap out? If so ill give it a go myself. Cheers.

It should be fairly easy to remove the valve on your toilet cistern as it is not a back to wall loo.
It might require a new seal washer on the water supply connection to fill valve, so first check what type of connection you have. If it is a copper fitting with brass nut, then replace the washer.

Or your easiest way to replace your valve is to just buy an identical Fluidmaster valve and only replace the valve part inside the cistern, leaving the stem part.
The valve is telescopic and is height adjustable by sliding up or down on it’s stem. Only thing holds it together is a round collar clip that you just slide up to be able to pull the valve off. Then push new valve on to same height as old valve was and push the round collar down to lock valve height.
Take a look at new valve first to see how it all goes together.
Note there are different versions of the Fluidmaster valve and best to get identical valve so to suit the stem.

Fluidmaster valves have a really simple cleaning routine, always worth doing before replacing.
Turn water off.
Undo the little threaded plastic rod from the lever by gently popping it out to the side where they connect.
Lift the lever to horizontal and turn the top black plastic cap a quarter turn and lift the cap off.
Check rubber for debris.
Hold a cup over the newly exposed valve top and turn the water back on for 5 seconds. Water will shoot out into the cup - be ready for it
Re-assemble.
Turn water back on.
This will often sort out a fluidmaster that is not shutting off properly.

Just noticed yours is the kind with a metal rod, not plastic, exactly the same but just lift the lever and twist, ignore line 2 of the above routine.

Hello mate.

Thanks for your advice! I tried cleaning the washer at the top but it still was happening so I ended up buying a flush and refill set and replaced them both. All pretty straight forward and I managed to not flood the place! All fixed.Thanks all for you help!
