I need to replace my torbeck bottom entry [snigger] cistern valve. I've found the entire unit for sale at Screwfix for Â£9.99. Do I also need to buy a new fibre washer for it? If so, does anyone know what size - Â½" or Â¾"?
Yes - always replace a fibre washer even if it looks OK they're so cheap it makes little difference. Whilst on that subject buy both (as they are so cheap) or take the valve with you when you buy. It's probably 1/2" though.
