Re: water falling from in between bowl and tank
A couple things come to mind, it is hopefully the lesser of the evils. First, the inlet/flush valve where it penetrates the tank could be leaking. Tighten the nut on the outside of the tank. The tank bolts could be leaking. Tightening may help as long as the bolts, washers, or gaskets have not been compromised. The last, and worst scenario is the tank is cracked, likely between the tank bolts and the tank grommet that seals the tank to the bowl.
