Ballcock valve not switching off due to limescale

Plus I think your is a bottom entry type, not side entry. Is the water pipe connection below the cistern tank?

Correct, the initial panic to get it fixed has been averted, it can survive being left overnight without it dripping but if i went away for longer then it would be a problem.

The problem i initially had was the overflow was leaking inside the bathroom on the right angle pipe before it goes through the tiles to the outside wall causing a flood and a large brown wet patch on the kitchen ceiling, but some silicon sealant has stopped that.

Start to panic again:

If the overflow is dripping during these cold nights, the overflow pipe can easily freeze and block. Then the cistern will overflow in your bathroom.

This is a reason why many homes don't have an overflow pipe to outside these days, but one that internally overflows into the toilet bowl.

The diaphram has a hole in it and I don't care what the rip off plumber has said it only needs a replacement diaphram.

No need to get so cross.

The picture posted does show metal on the flush part between the handle and the syphon. It is this that might benefit from a squirt of lubricant.

Thanks for the warning, it should survive the winter as have no plans to go out long enough and if it was going to be an issue i would turn it off in the bathroom until the ballcock valve is replaced or fixed.

Note that in the original photo, the long threaded bit of plastic "tubing" which contains the metal bar from the cistern handle to the actuator should be free from that bar in many models. Any build up of corrosion or limescale between them can cause problems.

I'd post a pic showing it rather than describing it, but I can't figure out how to since we lost our VM webspace.

Update...

I seemed to have fixed it just by spraying limescale remover all over the ballcock switch, this has caused it to initially stop the threat of it overflowing as well as make it fill the cistern a lot quicker, so i will leave it like this for now seeing there doesn't appear to be a threat of it overflowing.

Thanks for all advice from everyone.
