Flush constantly running and tank not filling

[Mcp975]

Hello- I’m not sure what sort of cistern we have (photo attached) but the water is constantly running after flushing and it does not seem to fill. Am wondering whether this is a job I can fix myself as we are really trying to keep to social distancing at the moment. Obviously if we need to get a professional in then that’s what we’ll do but id appreciate any advice.

At this stage I`m thinking perhaps the fill valve isn`t closing and water is overflowing into the cistern.

Bottom of the picture, white dome float on white arm, does the water stop entering the cistern if you gently pull it upwards? If yes then hold it up and see if the water stops flowing into the pan after a few minutes.

if I pull the white dome float up then the cistern starts to fill again and the water stops running when it reaches a level. If I don’t pull it up then the cistern remains fairly empty of water and it trickles constantly into the bowl?

I'm not a fan of the faulty valve you have so suggest that you change it to one from the Fluidmaster range.

Torbeck washer or replace the whole inlet valve with a viva skylo

Your flush valve is passing, either needs replacing or fixing.
Need a better picture of the flush valve. I think that's a Wirquin but not sure.

Torbeck opella. Theyre a bit Rubbish

That'd be the fill valve

Water gets into the wire on the cable to the flush. It then causes a build up of rust and prevents free moving, sometimes if you are lucky, you can put a silicone spray down the cable and free it up. Worth a try.

Thanks for all your help. Do you think the replacement is a job I can do myself? I’m ok with diy jobs - ish. We also have a leak where the sealant has gone from the pipe below the toilet basin - yuk!
Happy to give it a go if you think it’s a fairly easy job to replace the valve. Was going to buy the Viva Sanitary Skylo Dual Flush Valve?

Is your toilet a close coupled version? Cistern sitting on top of pan or can you see a pipe in between?

Yes- cistern sitting directly on pan.
