Who fixes a toilet that keeps running?
A plumber is the right first contact for a cistern that does not stop filling, a trickle into the bowl or a toilet that starts refilling by itself. Water Corporation recommends a plumber when a toilet leak is found; its guidance describes the inlet and outlet controls as possible areas to check, not a diagnosis from a symptom.
Tell the business whether the water stays inside the bowl or escapes onto the floor, whether the cistern is visible or concealed, and when the problem started. Ask it to confirm that it takes toilet repair work and can access any concealed cistern. Do not buy a replacement toilet on the assumption that the whole suite has failed.
What can I do while arranging the visit?
If water is running continuously, check whether the toilet has an accessible isolation tap and whether you can close it without force. Water Corporation explains that the property main shut-off is usually near the meter; if you cannot safely stop significant escaping water, phone a plumber or your water utility for guidance. Avoid forcing a stuck valve or opening concealed plumbing.
If the floor is wet, keep people away from nearby electrical fittings. A running cistern wastes water even when nothing is visible on the floor; do not leave it unchecked for days because the bill can rise. In a rental, tell the property manager promptly and ask who will arrange the plumber.
What should the repair quote cover?
Ask the plumber to separate the initial visit, parts, labour and any extra work that needs approval. A visible-cistern repair may differ from work behind a wall. Ask whether the business can obtain suitable parts for your cistern and what it will test before leaving.
The optional answers above go into one enquiry for the eligible businesses you select, with your confirmed job suburb. Review the recipients and brief before sending. If water is escaping now, phone a business directly rather than relying on an online quote reply.
Good questions. Plain answers.
Is a running toilet a plumber job?
Yes. A plumber can inspect the cistern, water supply and flush controls and tell you what repair is needed.
Does a running toilet mean I need a new toilet?
No. A symptom alone does not establish whether a part, cistern or whole suite needs replacing. Ask the plumber to assess it before approving a replacement.
What if water is on the floor?
Stop using the toilet and phone a plumber directly if water is spreading. Keep clear of wet electrical fittings.
Can I contact several plumbers?
For work that can wait for replies, select eligible local businesses and send one reviewed enquiry with your observations and suburb.
