Leaking Flush Tank at Bolts

[qosmioamit]

Hi
I have a flush tank that is leaking from the bolt that mounts the flush tank to the toilet. I tried tightening the bolt but that didn't help. There are two bolts, one on either side. Only one side is leaking. Any ideas on how to fix this? Can I apply some silicone sealant or do I need to take apart the whole flush tank?

Any help would be appreciated.

Thanks,

There are bolt and washer kits for rebuilding. Yes, take apart.
Make sure to only use corrosion proof materials. Brass or S.S. bolts and nuts and washers

You might also want to replace the big spongy gasket that connects the tank to the bowl.

The old gasket is often dried up and gets crumbly when the tank comes off.

If you get a tank to bowl kit it comes with a new gasket.

Only if you choose that style of kit.

You can buy tank bolts and washers kits, or just a tank to bowl gasket, or a kit with everything.

Update: I replaced the rusty old bolts with new brass ones but my problem is not resolved. The actual tank is cracked I think. I don't want to buy a new tank. Do you have any other suggestions?

Put some food coloring in the tank, preferably blue or green. If there’s a crack it will show up. If the tank is cracked it needs to be replaced. If you can’t get a new tank you need a new toilet. If its not cracked the dye will help you see where the water is coming from.
