Broken toilet flush / valve?

hopperdennis

Have purchased a property and the first flush seems to have broken it. The button won’t work and the water fill constantly drains away, have had to prop it up with a plunger to stop that contact flow. Any thoughts on what I need to buy to replace this, would it be just any cable flush valve?

Would this do the job? https://www.screwfix.com/p/fluidmaster-push-button-cable-dual-flush-valve/51173?kpid=51173&cm_mmc=Google-_-Datafeed-_-Heating%20and%20Plumbing

Looking at the description, it suggests it's 'twist & release' installation which would be great news - no need to actually remove the cistern. 

Check whether it's the same as the one in hopper's link. If so, buy and read :-)

It might even be repairable, but you'd need to remove it first and have an idea of what you are doing. Is there an isolating valve on the supply pipe to the inlet? If not, you'd need to cobble something together to stop the cistern continually filling when you remove the flush mech.

It's hard to tell, but you seem to have propped up the inlet valve. Before you change the flush valve, are you sure it's not the inlet valve that's faulty? If that kept on filling, the excess water would overflow through the flush valve into the toilet, so it might look like the flush valve is faulty.

It might be better to tie up the valve arm with a piece of wood across the cistern using string or a cable tie.

It might just need adjusting using the screw on the top.

Yes this is what’s happening. The flush button seems dead, and the water is constantly flowing down into the toilet. Have had to prop of the release lever (not the correct term) with a plunger to stop it

What do you mean by ‘across the cistern’? I think I know what the valve arm is but thus sounds above my pay grade possibly.

What can happen with fluid master valves (like you have ) is the wire that goes to the button gets stuck and doesn't release properly holding the float up and you get constantly running water into the pan 

Release the button from the cistern and relax the cable and see if that solves it , if it does then re route the cable , if not the valve that's been linked to from Screwfix should be a direct swap and should fit onto the base of your valve

Had this problem with mil toilet, a good dose of WD40 down the cable inside seems to have worked for now, time will tell

If you put a piece of wood from one side of the cistern to the other or front to back as long as it cant slip off, it doesn't have to be thick just the size of a ruler or coat hanger,

Then tie a piece of string under the little arm with the screw on top on to the wood so it is holding the float up to stop the water flow.
