Finding the cause.
The plumber checks the cistern parts, the connections and, if the symptoms point there, the drain. A running cistern is usually an inlet or outlet valve. Water at the base is usually a seal or connection. A pan that backs up is a drainage problem in a toilet costume.
For a replacement, the existing outlet position, set-out measurement and water connection decide what fits. Two suites that look identical in a catalogue can have different set-outs, and the wrong one means pipework changes. Check before you buy.
What to send us
Note whether the problem is constant or only happens when you flush. That alone narrows it down. Photos of the toilet, cistern and connections help. If wastewater is backing up, stop using that toilet and avoid the overflow.
What moves the price
The fault, parts availability, access and repair-or-replace set the scope. For a replacement, check whether the price covers the suite, removing the old one and taking it away. They are often quoted separately. Typical toilet repairs & installation prices in Ipswich ↗ Toilet blocked right now? What to do first ↗
