A running tank, an external leak, and a blocked drain call for different assessments. Describe the symptom before choosing repair, replacement, or drain clearing.
Running water or repeated refilling
If the toilet sounds as though it is filling between uses, include that detail in the request. Water moving through a toilet can be less obvious than a drip on the floor. EPA WaterSense includes toilet leaks in its home-maintenance guidance.
A repair estimate should identify the component being serviced, the proposed parts, and the checks after repair. You do not need to choose a replacement part before contacting a provider. If the make or model is available in your records, keep it for the service conversation.
Water near the base or supply connection
Describe exactly where the water appears and whether it follows a flush, appears while the fixture is unused, or has an unclear pattern. A photo may help the attending provider, but its location alone does not establish the cause.
If removing and resetting the toilet is proposed, ask whether the price includes a new seal, assessment of the mounting condition, and any additional work if a problem is found underneath. Clarify finish or floor repairs separately.
Repair or replace the fixture
A repair option should explain the fault, parts, and labor. A replacement option should name the model and include delivery, installation materials, removal of the old toilet, and any access or mounting work that applies.
For a customer-supplied toilet, ask who checks compatibility and how product defects or missing parts affect a return visit. Compare the full installed scope with the repair option on the estimate worksheet. We have not verified a like-for-like local published toilet-repair range.
Common questions
Does a running toilet always need replacement?
A running symptom alone does not establish that the whole fixture needs replacement. Ask for the diagnosis and the repair option before comparing a new fixture.
Will clearing the toilet fix other slow drains?
That depends on where the restriction is. Describe every affected fixture and ask which line the proposed work covers.
What should I include in the request?
State whether the issue is running, leaking, or flushing; when it happens; whether other fixtures are affected; and the property ZIP code.
