I just noticed these cracks in the bowl of my toilet. It is not leaking water. Can I assume that these are just cosmetic cracks in the glazing? Or, should I worry about a catastrophic failure?
I installed this toilet myself about 20 years ago. It is on tile over a concrete slab; it is solidly mounted, there is zero rocking. It is an expensive pressure-assist toilet so I would rather not replace it.
Edit: Found a crack on the outside.
