how toilet works

wazza

i have a modern toilet system. not the old type which has a large ball on a rod which shuts the water supply off in the tank. the new mechanism is different. the thing is during the day it works fine. the water supply cuts off when the tank is full. however during the night when one flushes the toilet the water supply takes ages to shut off. the tank gets full but it keeps filling. the excess water drains away in the pan. from what i can deduce is that at night the water pressue is at its highest and the tank mechanism finds it hard to shut it off. if i were to turn on the bath and basin taps on this helps in shutting off the water supply early in the tank.

Try ringing the local plumbers merchant's to see if they have any ideas, otherwise it sounds like you need to ask them for the name of a reliable plumber. _pale_

This is a common problem with these chesp plastic workings. Try spraying the mechanism with silicone spray or get a replacement mechanism.

Sounds as though you have a Fluidmaster valve. Alot of guys don't bother to remove the top from these to flush the debris through when they fit them, and it can interfere with them. It's quite awkward to do and even more awkward to explain how it's done. The top twists off of them and then you need to put a cup over remaining mechanism and then restore the water supply to flush it. It may be least hassle to confirm that it is a Fluidmaster (other possibility is a Torbeck valve) and simply replace, following the commissioning procedure in the instructions.
