Thanks for previous advice on boiler choice.
Todays problem is my toilet cistern overflows usually overnight and i am looking for advice on a replacement ball valve.
The existing is very old plastic crudded up with scale,noisey when refilling and leaks.
So please can someone reccomend an up to date ball valve to fit this plastic cistern,its not close couple and is side inlet,mains water supply.
Thanks.

'Torbeck' and 'Fluidmaster' equilibrium valves are popular replacements for conventional ball valves.

Well thanks again for advice.
Fluidmaster now fitted and its really a 1000% improvement from existing valve.
