Toilet keeps running?

Constant running, occasional refilling or an overflow?

Tell the provider which of these is happening. A tank that keeps filling is different from a bowl that is rising toward the rim or water appearing on the floor. A toilet can also lose water quietly between uses.

If the bowl is rising or wastewater is backing up, stop flushing it. Mention other affected drains at the start of the call. Keep people away from contaminated water. For water outside the fixture, describe where it appears without moving the toilet or taking connections apart. The fixture overview covers these separate repair situations.

A simple check for a quiet tank-to-bowl leak

For a toilet that drains normally and has a safely accessible tank, EPA WaterSense describes a food coloring check. Put a few drops in the tank, then leave it unflushed for ten minutes. Color reaching the bowl indicates a tank-to-bowl leak. Flush afterward to prevent staining.

Skip this if the bowl is blocked, rising, or the tank is difficult to access. Follow the fixture manufacturer's instructions. This check shows that water is passing through; it does not identify every failed component or confirm that the toilet needs replacement.

Use the symptom to describe the visit

Note whether the sound is continuous or the tank refills occasionally when nobody has flushed. Mention whether the bowl shows movement, whether water is outside the fixture and whether the problem began after recent work. Report observations from normal use rather than repeatedly flushing a troublesome toilet.

EPA identifies worn toilet flappers as one common cause of leakage. That does not make one replacement part suitable for every fixture. If you already have the make, model or earlier repair record, keep it ready. Tell the provider which symptom the previous visit changed and which one remains.

Prepare a useful repair request

1. Continuous running or the approximate interval between refills.
2. A rising bowl, slow drainage or other backed-up fixtures.
3. Any water outside the toilet and where it first appeared.
4. The model or existing part record, if already known.
5. A recent repair and what changed afterward.
6. A safe-access or building-management arrangement.
7. Any unusual usage shown on the bill, without assuming this toilet is the only cause.

Repair a component or replace the toilet?

Ask the provider to identify the fault and explain whether a compatible repair will restore normal filling and flushing. Confirm what check is included afterward and who to contact if the same symptom returns.

For replacement, ask for the exact fixture and the work included: removal, fitting, connections, disposal and any mounting or floor issue found during the job. Clarify which finish repairs are excluded. A new toilet and a small tank-component repair cover different work, so compare the scope before the total.

Confirm the assessment charge and approve any additional work before it starts. The plumbing estimate checklist sets out the questions to keep in writing.

Call about a running or leaking toilet

Explain whether the tank keeps filling, the bowl is backing up or water is outside the fixture. Confirm the visit charge and appointment details.
