Toilet leak beneath one tank-to-bowl bolt? I replaced the flush valve on my toilet this week. ...

I replaced the flush valve on my toilet this week. I notice the tank-to-bowl bolts were pretty corroded, so I replaced those, as ably as the gasket underneath the tank. I didn't see any cracks. When I flush the toilet, it leak underneath the right bolt. I undid everything and retightened it, and it's still leak. I have NO belief why it could be doing that. Any suggestions? Thanks!
Ours did this for awhile and we could not figure it out. We stuck a bowl underneath to corner the drips while we thought about a solution. Then sometime it just stopped leak on its own. Like it sealed sour after awhile. Weird.


Turn off the dampen and flush the toilet. Drain and dry all of the parts. Make sure at hand is no residue from old washers around the bolts. Put silicone caulk on both sides of the rubber washer for the bolts connecting the cistern to the bowl. Don't be skimpy, Anything that squeezes out is OK. Let dry as recommended on the caulk tube.

Something was not cleaned properly the first time, and to be precise why you have this overflow.
Answers:    If the silicone caulk doesn't work for you, or you don't want to deal beside that, the rubber seal between the container and the bowl can be replaced quite confidently. You can buy them at most hardware stores.
