    Wouldnt isolate as chances are you will start a new leak.
    That leak you have will only leak if the toilet is flushed so if you arent there it wont leak.

    Looks like your arrow is pointing to the flush pipe cone to me .
    Under a couple quid in Plumbfix (or screwfix)

    Although look at the pipe at the very top near the cistern in the second pic,judging by the gunk I’d check there first as it looks like it has leaked there and just gone down the outside of the pipe.

    Flush pipe leaking where it comes out of the cistern.

    Best call in a plumber.

    I'll isolate the toilet drain the cistern then change the pipe from cistern I guess.

    The toilet also doesn't flush everything without using the toilet brush. Is it the way the toilet flushes the problem?

    Change the isolating valve. Change the flush cone and cistern connection. Change the internal syphon valve. Change the fill valve (while you're are at it). Change the WC connection to soil pipe if it leaks, it's a bodged connection. Empty bowl of water and check inlet to pan for partially blocked hard water lime deposits. Or get a Plumber in.:)

    That's usually a problem not seen unless one takes out the flush pipe. Best of luck.:)

    I tried to just change the washer but still leaking. I ripped out the two old ones and put new one in. I'll go plumbing change everything like you said as I guess they're all connected

    Changed flush pipe and and syphon. Can see in photos. It's now leaking where arrow is pointing where connection joins cistern. Do I need to cut the flush pipe a bit shorter when pushed up into syphon? Does the flush pipe need cutting perfectly at 90 degrees to prevent a leak? 20210902_195711.jpg 20210902_200544.jpg 20210902_195037.jpg

    It doesn’t help if it’s straining. How far into the syphon does it go? Also your arrow indicates it could be running down the syphon thread, if it is, then either the flush pipe is pulling it out of kilter, or it hasn’t sealed properly inside.

    At a guess about 3 or 4inches but would need to take it out tomorrow morning (my wet vac is too noisy at this time of night) and measure to be sure. I'll cut off another 5mm tomorrow

    Its actually dripping right off the cistern on edge of plastic thing onto flush pipe below. Out of kilter meaning coming out at an angle? Looks like coming out plumb to me. I noticed also after flushing lots of water is still left compared to previous syphon

    Yes, what I meant was, If the flush pipe is pulling it slightly, then it’ll leak. Try removing the flush pipe first, leaving the syphon in place with a small amount of water in the cistern and see if it still leaks - if it does, you know it’s bugger all to do with the flush pipe.
