Toilet repair & installation, with a clear plan.

A toilet that runs between flushes can waste water quietly. A toilet that rocks, leaks, or repeatedly blocks may need a different approach. Describe the symptoms separately so the assessment can focus on the tank, the fixture connection, and the drain as appropriate.

  • Running toilet and flushing faults
  • Leaks around the tank or base
  • Toilet replacement and fit checks
  • Recurring toilet blockage assessment

Running, leaking, or not flushing properly

Tank components, water supply, and the toilet connection can each cause different symptoms. Note whether water appears only after flushing or remains present continuously. If the bowl is rising, stop flushing and avoid using it until the blockage is addressed.

Choosing a replacement toilet

Measure the available space and discuss the existing connection before buying. Bowl shape, seat height, accessibility needs, and water use all affect everyday comfort. A replacement may also reveal work needed at the shutoff valve or floor connection.

When a clog is more than a toilet problem

If the shower or nearby sink backs up when the toilet flushes, the issue may extend into shared drainage. Mention other affected fixtures when you call so a repeated toilet blockage is not treated as an isolated symptom.

Your questions, answered.

Can a new toilet use the existing connection?

Often it can, but fit and the condition of the flange, floor, and supply valve should be checked before installation.

Should I keep flushing a blocked toilet?

No. Repeated flushing can overflow the bowl. Stop using the fixture and arrange help.
