I replaced the gasket and tank bolts of a 10+ year old toilet. The tank bolt kit included rubber-fiber and stainless washers. The kit warned about tightening the bolts too much and potentially cracking the porcelain but I still tightened them a fair bit - enough to deform the rubber washers.
When I filled the tank, water dripped out in a steady stream from both sides. Tightening the nuts a bit more didn't seem to make much of a difference.
I don't see any crack in the porcelain and the contact surface around the washers seems pretty flat without any noticeable pits, bumps, or cracks.
- Is there any "trick" to making the joints leak tight or do I just need to keep tightening?
- How likely am I to crack it if I tighten more?
- Am I better off adding some pure silicon caulk to make it watertight or do I just keep tightening until the leaking stops and hope the porcelain won't crack?
- Any other suggestions?
Thanks
