Common Toilet Problems
Toilets contain several moving components that naturally wear over time. Fortunately, many faults can be repaired quickly before they develop into larger plumbing problems.
Some of the most common issues we repair include:
Constantly Running Toilets
A toilet that continues to run after flushing wastes significant amounts of water and can noticeably increase your water bill.
Common causes include:
-
Worn outlet valve seals
-
Damaged flush valves
-
Incorrect water level adjustment
-
Faulty inlet valves
-
Debris preventing the valve from sealing correctly
We'll identify the cause and replace the faulty components to restore efficient operation.
Blocked Toilets
Blocked toilets are one of the most common plumbing callouts.
Blockages may be caused by:
-
Excess toilet paper
-
Foreign objects
-
Sanitary products
-
Wet wipes
-
Children's toys
-
Tree root intrusion
-
Damaged drainage pipes
-
Sewer line blockages
Our plumbers will locate the cause of the blockage and safely clear the obstruction while checking for any underlying drainage issues.

Faulty Inlet Valves
The inlet valve controls how the cistern refills after flushing.
When an inlet valve begins to fail, you may notice:
-
Slow filling
-
Constant trickling
-
Water overflowing into the pan
-
Noisy cistern filling
-
Inconsistent water levels
Replacing a faulty inlet valve restores reliable flushing while helping reduce unnecessary water consumption.
Leaking Flexible Hoses & Water Pipes
The water supply connecting your toilet can also develop leaks over time.
We repair and replace:
-
Flexible braided hoses
-
Copper water supplies
-
Isolation valves
-
Compression fittings
-
Toilet connection pipework
Addressing these leaks early helps prevent damage to flooring, cabinetry and surrounding finishes.
Worn Outlet Valves, Flush Seals & Cone Rubbers
The outlet valve allows water to leave the cistern during flushing before sealing again.
Over time, seals and cone rubbers can deteriorate, causing water to continuously leak into the toilet bowl.
Signs include:
-
Constant water movement inside the pan
-
Water running long after flushing
-
Increased water bills
-
Frequent cistern refilling
Replacing these components is often a straightforward repair that restores the toilet's efficiency.
Faulty Mini Stops (Isolation Valves)
Mini stop valves allow the toilet water supply to be isolated for servicing or repairs.
Older valves can become difficult to operate or begin leaking around the spindle.
Replacing faulty isolation valves improves safety and makes future maintenance much easier.
Toilet Repairs & Servicing
Routine servicing helps keep your toilet operating efficiently and can prevent unexpected breakdowns.
Our servicing may include:
-
Inspecting internal cistern components
-
Replacing worn seals
-
Adjusting water levels
-
Checking flush performance
-
Inspecting inlet valves
-
Testing isolation valves
-
Checking for leaks
-
Tightening loose fixtures
-
Inspecting pan stability
Preventative maintenance can significantly extend the life of your toilet.

Repair or Replace?

In many cases, replacing worn valves, seals or pipework is all that's required to restore reliable operation.
However, replacement may be recommended where:
-
The toilet is heavily cracked
-
Replacement parts are no longer available
-
Water efficiency can be significantly improved
-
Multiple components have failed
-
You're renovating your bathroom
-
You'd like to upgrade the appearance of your bathroom
We'll always explain your options and recommend the most practical, cost-effective solution.
