Short answer
Check for continuous water flow in the toilet cistern, indicating a failing valve or seal needing immediate attention. Inspect the area around the toilet base for signs of moisture or staining. Avoid flushing repeatedly if the toilet is blocked to prevent overflows and further damage.
If the toilet is the only one in the house and fails to flush, it is urgent.

How to recognise it
- Continuous running water in the cistern typically points to a failing valve or seal needing replacement.
- Weak flushing often leaves residue in the bowl, indicating restricted water flow or partial blockages.
- Pooling water around the toilet base suggests leaks from seals or connections that require urgent attention.
- Visible cracks in the toilet pan may lead to leaks and affect the structural integrity of the toilet.
- Toilets that don't clear properly after flushing often have blockages in the soil pipe or U-bend.
- Gurgling noises from nearby drains during flushing point to possible venting or drainage issues needing investigation.
- Persistent unpleasant odours around the toilet area can be due to a failed seal or a slow water leak.
Common causes
- A faulty flush valve or siphon results in continuous water flow by failing to maintain a proper seal.
- Worn or improperly fitted pan connector seals can cause leaks at the base by allowing water seepage.
- Mineral build-up inside the flush mechanism restricts water flow, leading to incomplete flushes needing cleaning.
- Blockages from inappropriate items flushed down cause backups, leading to inefficient flushing and overflow risks.
- Stress cracks or age-related wear in the toilet pan increase the risk of leaks when under pressure.
What you can do yourself
- 01Turn off the cistern's isolating valve immediately to prevent water damage if a leak or overflow threat arises.
- 02Avoid flushing a clogged toilet repeatedly, as this reduces overflow risks and prevents potential flooring damage.
- 03Use a toilet auger gently on minor blockages to restore proper flow without adding stress to the drainage system.
- 04Regularly check seals for moisture signs to catch and address leaks before they escalate into major problems.
What the plumber does
- Repairing or replacing the cistern valve addresses continuous water flow and helps reduce water wastage effectively.
- Replacing a cracked toilet pan prevents further damage and ensures the toilet remains safe for normal use.
- Clearing blockages in the soil pipe resolves ineffective flushing and significantly reduces overflow risks.
- Installing a new flush valve or siphon improves flushing power, resolving issues with weak water flows promptly.
- Applying plumbing sealant to secure connectors can stop minor leaks, provided all components are in good condition.
How the job usually runs
- 01Inspect all toilet components thoroughly to diagnose any faults and identify repair or replacement needs.
- 02Shut off the water supply by turning the isolation valve to prevent water entry during repairs safely.
- 03Repair or replace any faulty components identified to restore full operational functionality of the toilet.
- 04Test the flushing mechanism by performing multiple flushes to confirm proper water flow and waste removal.
- 05Check for leaks by inspecting seals and joints after flushing, ensuring no drips or moisture are present.
What the price depends on
PlumberSites does not publish a fixed price. That is agreed with the firm you appoint. Differences usually come from:
- The complexity of the issue, such as concealed blockages or internal cracks, often increases the cost of repairs.
- Access difficulties in tight spaces or needing specific fixtures may require more time and specialised tools.
- Material and component quality play a significant role, with durable parts potentially reducing future repair needs.
- The age and condition of existing plumbing can increase costs if widespread upgrades or replacements are necessary.
- Labour costs vary depending on the professional's expertise and the time needed to complete complex repairs.

Questions
What should I do if my toilet won't stop running?
A continuously running toilet often points to a failing flush valve or seal. First, check the valve for visible wear or misalignment. Turn off the water supply to prevent wastage and then consider replacing the valve or seal based on observations. If you're unsure, consult a qualified plumber to inspect the flush mechanism and confirm the need for repairs or parts replacement.
Why is there water pooling around my toilet base?
Water pooling around the base usually signals a leak from the pan seals or connecting pipes. Check for visible cracks in the pan or loose seals. Moisture might also indicate a blockage causing back-flow. Avoid using the toilet until it's examined by a professional, as continued leaks can damage flooring and lead to further complications.
How can I improve weak flushing of my toilet?
Weak flushing might be caused by mineral build-up or partial blockages in the flush mechanism or pipes. Regularly cleaning or replacing the flush valve may enhance water flow. If issues persist, inspecting and possibly clearing blockages in the soil or U-bend pipe is recommended. Consult a plumber for a complete diagnosis if these steps don't resolve the issue.
Is it better to repair or replace an old, cracked toilet pan?
An old, cracked toilet pan poses significant leakage risks and potential structural issues. Repairing minor surface cracks might temporarily address leaks, but replacement ensures long-term integrity. A new pan offers modern efficiencies and reliability, preventing unexpected failures. If budget allows, replacing the pan usually offers greater peace of mind. Consult a professional to weigh repair against replacement given the age and extent of the damage.
