Leak on pipe into cistern

    Hi. Fairly new to this but I have changed the syphon in the toilet which has worked well but I have an issue with a leak when reattaching the side entry float valve to the inlet pipe. I have used teflon tape on the thread, wrapped around it clockwise up to 10 times but still have a slow leak.

    Is a rubber bung/washer required inside the nut (see attached) or should the teflon tape be enough to provide a waterproof seal. There seemed to be a small broken washer inside. I have tried the teflon tape a few times and tightened more each time but the leak persists.

    Thanks

    To me that looks like you have cross threaded it.

    I agree. The threaded section doesn't protrude far enough from the cistern meaning the water inlet pipe is at an angle to it. If it hasn't been totally messed up you might be able to rescue it by slackening off the nut on the inside of the cistern, re-tightening the one on the outside thus moving it out a little.

    Its the fibre washer inside the nut that creates the seal.

    Ok thanks so no rubber washer needed inside the nut? Will I clear out the broken washer/bung inside? Is the teflon tape enough to form a seal? I have a spare threaded section I can use

    I may have too much tape on it (x10 times around) as each time I tried to tighten the nut it went on at an angle. I'll try to make sure that the threaded section is straight and not at an angle. There isn't any spare threaded section inside the cistern - see attached

    Fibre washer required inside the nut.putting tape on the thread section does nothing to seal it.There should be no tape fitted to the threaded section

    You need to replace the threaded section, now it's damaged - the pipe might burst off otherwise
