I have an old-style toilet that has the tank bolted to the wall; there is a leak at the bottom of the tank when the toilet is flushed and water travels through the 2" diameter pipe into the bowl. There is a slight vertical misalignment between the tank and the bowl (about 3/8" over a span of 5"), and the new neoprene washers, tightened down hard, don't quite stop the dripping when the toilet is flushed. Any suggestions?
