Toilets in Bellevue homes — leaks, running, and weak flushes

A toilet has three failure points homeowners actually meet: the flush (weak, incomplete, or doubling), the fill (a tank that never stops running and quietly wastes thousands of gallons a month), and the seal (water pooling at the base from a failed wax ring or a cracked bowl). Each has a distinct cause and a distinct fix, and most are a $10-$30 part rather than a service call. This section covers the diagnosis for each — running, weak flush, gurgling, base leak — and the one symptom, a gurgle that tracks with other drains, that means the problem is in the sewer line, not the toilet.
