I live in a hard water area. About 6 years ago i had a new bathroom suite fitted. The toilet system uses a bottom entry Torbeck valve.
A few years back the valve would not shut off therefore the tank was overfilling. I had a new Torbeck valve fitted. Now the same problem has returned. The tank is slowly overfilling. When i shut off the water supply the overfilling stops. This narrow it down to the Torbeck valve.
I have done a search on the internet and found it is a common problem. Something to do with dirt in the seal. Have read somewhere that it is recommended to swap it for something called Fluidmaster. Is this possible?
