Direct answer
A leaking toilet can waste water from the cistern into the bowl, leak from the supply connection or release wastewater at the base. Identify where and when water appears before choosing a repair.
What can cause the problem or change the decision
| Possible factor | What to record safely |
|---|---|
| Inlet valve not shutting off | Dry visible surfaces and observe |
| Flush seal leaking into bowl | Add no chemicals to the cistern |
| Supply hose or isolation valve leak | Listen for refilling without use |
| Pan connector or base failure | Stop using if water appears at the base |
Safe checks before professional work
