I had to replace my valve did not have to remove the toilet to do this I think it just depends on the make/model of the toilet.. but my leak was from the joints in the piping. Until I could get it fixed I took a 2 liter/quart milk jug (paper) opened one long side like a door and placed it under the toilet so the flap was against the wall and it dripped into the milk jug.. remember to empty it every day if you do this till you get it fixed .. I now leave it under there just in case...
