Replaced the valve and float assembly in our toilet cistern, since it had gotten blocked up or something and was taking forever to fill the cistern. Whoever designed that toilet should be shot; it does a wonderful job of hiding pipes from people who're offended by such sights, but leaves almost no room to work with when trying to screw and unscrew things, which is a bit of a a bugger when the seals have welded themselves to the toilet/pipes and need a wrench to loosen them. The old valve also used to take ages to refill the cistern and made a terrible racket while it was doing so, to the point that me and mum had to raise our voices to be heard when trying to talk to each other in the next room while it was refilling, even when it was brand new, and the new valve assembly is much quieter and quicker.
You seem to be lost in your own thoughts.
