What This Problem Means
Understanding Toilet Problems
A clear, honest explanation of what is happening so you know what you are dealing with.
Toilet problems cover the range of issues that beset a toilet: a toilet that runs constantly, flushes weakly, blocks easily, leaks at the base, or has a cistern that will not fill or shut off. A running toilet is one of the most common and most wasteful water leaks in a home, while a toilet that leaks at the base can damage the floor and the room below. All of these are fixable, but the repair depends on identifying the failing part.
A toilet is a relatively simple mechanism, but the causes of a problem can be several. A running toilet is usually a worn flapper or a faulty fill valve. A weak flush can be from a blocked rim, a low water level or a poor flush design. A leak at the base is more serious, as it can signal a failed wax seal or cracked bowl, which should be dealt with promptly to avoid water damage.

FAQs
Toilet Problems — Frequently Asked Questions
Straight answers to the questions customers ask us most about this problem.
Why does my toilet run constantly?
A running toilet is usually a worn flapper or a faulty fill valve that cannot seal. Replacing the worn part is a simple, cost-effective fix.
Is a toilet that leaks at the base serious?
Yes. A leak at the base can damage the floor and the room below. It is usually a failed wax seal or a cracked bowl and should be fixed promptly.
Why does my toilet flush weakly?
A weak flush can be from a blocked rim, a low water level or a poor flush mechanism. We check the cause and restore a proper flush.
How much water does a running toilet waste?
A running toilet can waste many thousands of litres a year. Fixing it usually pays for itself quickly through lower water bills.
Should I repair or replace my toilet?
If the toilet is sound and a single component has failed, repair is cheaper. If it is old, cracked or inefficient, replacement is often the better investment.
