Re: quite toilets
No mate! This is a very valid question, I recently replaced a noisy ball cock in a WC cistern with a "Fluidmaster" float valve. They're not cheap, about €20 odd, but it's virtually silent and you can adjust the amount of water the cistern takes on after each flush- which might be of interest if you are green minded and want to conserve some water. I bought it at a local independent plumbers merchant. They're a great idea in an ensuite bathroom.
