Leaking Toilet

Leaking toilets can often go unnoticed, especially if the leak is silent or out of view. But if you spot a leak or hear a hiss, don’t panic. Our plumbers are never far away and can provide a fast fix and expert advice on repairing or replacing your leaking toilet.

Common causes of a leaking toilet

If you have trouble flushing the toilet, find that it won’t stop running or discover any cracks, leaks or flooding, it’s best to get it checked before it causes any serious damage to your property. Common causes of leaking toilets include:

  • A faulty inlet valve washer that causes water to overflow from the cistern into the bowl
  • Broken seals that cause water leakage on the floor or at the base of the cistern
  • A broken outlet valve or washers that cause leaking and prevent the toilet from flushing fully.

How STS Plumbing can help

We’re happy to do all the dirty work, so you can get back to your regular routine. First, we’ll test the system to determine where the leak is coming from and replace any faulty washers, inlet or outlet valves. If your toilet needs replacing, we’ll help you select a dual-flush toilet that will give your bathroom a fresh new look and help you save on water costs.

Our plumbers have a wide range of replacement parts on hand, so we can fix any small problems on the spot. If we think it’s cheaper to replace the toilet rather than repair it, we can order in the cistern or full toilet suite and install it for you.
