Toilet flaps are easy to change , just bend the ears around the handles and undo the chain to the flush handle then install a new one the same way. If you want to change the plastic or brass over flow tube assembly then it can be a little difficult. 1 shut off the toilet stop. 2 flush the toilet and hold the flush valve open so it drains most of the water. 3 unscrew the toilet supply nut ( water will spill out from inside the ballcock). 4 vacuum out the tank so its dry and then unscrew the 2 or 3 tank bolts . 5 pull the tank then unscrew the big nut on the over flow. 6 put a bead of silicon on your new toilet over flow rubber gasket then install it and tighten the nut, then do all the steps backwards and when you put your toilet tank bolts back in just for safety put a bead of silicon on your toilet tank bolt rubber washers and you shouldn't have any problems with any leaks.

Cut off the toilet water supply somewhere. Remove old flapper and go obtain a close cousin. Put it back in the same location. Cut on the water then test your workmanship.
