Simulator — practice and planning only

Toilet Running Decision Simulator

Practice safe decisions when a toilet keeps running, refilling, or leaking.

Scenario: You hear water running from the toilet, or the toilet keeps refilling after flushing.

A running toilet is one of the most common home annoyances. It can often be documented and planned calmly — unless water is on the floor.

What do you notice?

Is water on the floor or leaking below the toilet?

Are you in an apartment or shared building?

Can you safely observe inside the tank (lid off, without forcing anything)?

Answer the first two questions to run the simulation.

This was a simulator practice — not a real diagnosis

This simulator is for practice and planning only. It does not diagnose problems, replace emergency services, or replace licensed professionals. In any real emergency, stop and call for qualified help immediately.

Know When to Call a Pro

Call a plumber for floor leaks, stuck valves, active leaks at the base, or if you are unsure.
