How much water does a running toilet actually waste?
Depends how badly it's running, and the spread is enormous. A flapper seeping just enough to trickle is a small daily number you'd never notice. A fill valve stuck wide open moves more water in a day than a household of four uses on purpose.

Water around the base — is that the wax ring or the flange?
Both feel identical from above, and the difference decides whether it’s a short job or a real one. The wax ring seals the toilet to the drain. The closet flange is the collar bolted to the floor that the toilet fastens to. Wax fails with age. A flange failure means the thing the wax seals against is broken.
The tell is movement. If the bowl is solid and you only see seepage after a flush, a fresh wax ring usually handles it. If the toilet shifts when you sit, stop using it — every rock breaks the seal you’d be paying for. In Red Oak houses built before the mid-1980s we find cast iron flanges rusted thin enough that the bolt slots have crumbled, and those get replaced rather than re-sealed.
What does a rocking toilet do if you leave it?
It leaks a little every flush, into whatever is under it. On a pier-and-beam house that's a subfloor, and rot spreads out from the flange until the floor around the toilet goes soft. Press near the base with your thumb — if it gives at all, the damage is already past plumbing.
On the slab foundations most of Red Oak sits on there’s no subfloor to rot, which sounds better than it is. The water goes sideways instead, under vinyl or laminate and into the vanity and the baseboards. Either way, the fix costs less the week you notice the wobble than the month you notice the smell.
Why does the same toilet clog over and over?
A toilet that clogs once is a toilet that had something in it. A toilet that clogs every few weeks is telling you about something else — a partial blockage further down the branch line, a vent problem starving the flush of air, or a low-flow model from the first generation of them that never moved solids well to begin with.
We'd rather find out which before selling you a new toilet. If the same bathroom also has a slow tub or sink, the problem isn't the fixture at all, and it's a drain cleaning call. If the bowl itself is cracked, or it's an early 1.6-gallon unit that's never worked right, toilet installation is the better spend.
