Leaking Toilet Tank Bolt

[Heallytim]

One of my toilet bolts is leaking water on the floor every week or two. Do I tighten it gently? I don’t want to crack it. If that doesn’t work, do I add a washer? Or should I just go ahead and add a washer before I tighten ? Thanks

I usually lean on the tank slowly but firmly and tighten the bolt.

It depends on the tank bolts. Some tank bolts are double nutted. One set of nuts create the seal but are concealed between the tank and the bowl and the second set that you see are to hold the tank to the bowl.

If your tank is making full contact to the bowl then further tightening is not likely going to fix the problem. If it isn't making contact then I would do as John mentions and add downward pressure to the tank and snug up the nut...

If that doesn't fix it then buy a good solid brass replacement bolt kit and redo it.
