Hi, I live in a small block of flats and recently the main toilet has started making a REALLY load 'fog horn' noise when flushing (the toilet in the en suit doesnt do it) Ive also noticed I can hear the same thing happening in the flat below. Is that just a coincidence thats happening the same time as me or is it a fault with a water tank in the loft or something? Any help would be much appreciated.

its just your Float Operated Valve (ball valve) washer. its gotten too hard. as the mains water gets colder (this time of year)it hardens up the washers and as they cant flex properly they vibrate with the water pressure against it. you can get the washer changed or some plumbers prefer to replace the whole FOV depends who you get. should be looking at minimum call out approx £35 plus the washer, if its a torbeck they're about £5 or £6! or give it a go your self, then get a plumber out when you cant stop the drip lol!
its probably a part 2or part 3 float valve, these have a diaphragm washer in them , get to your local merchants or b and q whatever and get one, easy to fit , 5 min job, dont forget to turn off the water first though !! there may be a isolating valve under the cistern on the supply pipe
