Brisbane plumbers’ advice for preventing leaking taps and toilets

As veteran plumbers serving Brisbane homes for over 20 years, we’ve seen the costly damage that seemingly minor leaks from taps, toilets and other plumbing fixtures can cause over time. While drips may seem insignificant, that constant drip, drip, drip adds up quickly – potentially wasting thousands of litres of water per year while also enabling mould growth, structural deterioration and more.

Fortunately, many of these leaks are preventable through proper maintenance and timely repairs. Here’s our professional advice for stopping leaky taps, running toilets and other plumbing fixture leaks before they turn into expensive nightmares:

Stop taps from dripping

A dripping tap may seem harmless, but each drop escaping can waste up to 20,000 litres of water annually. Not only is that expensive, but leaking taps enable harmful mould growth on surrounding surfaces over time. To prevent tap leaks:

  • Replace worn washers, o-rings and valve seats promptly
  • Use plumbing-approved tap lubricants and sealants
  • Ensure taps turn off fully and have working shut-off valves
  • Consider updated retrofit taps with ceramic disc valves
  • Install aerators to reduce leak-causing water pressure

With some taps, replacement may be more cost-effective long-term than constant leak repairs.

Stop toilets from running

Toilets that constantly run between flushes drive up water bills significantly, and can signal larger drainage issues. Stop running toilets by:

  • Adjusting or replacing faulty flush valve assemblies
  • Checking for cracked or deteriorated flush valve gaskets/seals
  • Removing obstructions or debris in the trap or flush mechanisms
  • Addressing tank-to-bowl water level imbalances

For persistent trouble toilets, replace them with new, high-efficiency toilet models that have improved flush mechanisms.

Check appliance hose connections

A lot of appliance-related leaks stem from deteriorated rubber hoses and loose hose connections on washing machines, dishwashers, refrigerators and more. Routinely:

  • Inspect hoses for cracks, kinks, blisters or deterioration
  • Ensure connection points are tight and use plumbing-approved tapes
  • Replace rubber hoses every 3-5 years as preventative measure
  • Use stainless steel braided hoses where possible for added durability

Never ignore a dripping or slow hose leak – it will worsen rapidly over time.

Inspect exterior hose bibs and siamese connections

Those hose connections on the exterior of your home allow water entry points for leaks too. During seasonal hose removal:

  • Check for cracked housings or damaged valve stems
  • Replace worn backflow preventer valves
  • Make sure shut-off valves operate smoothly

Any moisture entering exterior walls provides an entry point for termites and wood rot.

Watch for moisture stains and mould

Discolouration, moisture stains and active mould growth are some of the first signs of plumbing leaks lurking behind walls, ceilings and floors. If you notice:

  • Wood flooring that feels spongy or has darkened boards
  • Wall, baseboard or ceiling stains and moisture marks
  • Areas of active mould growth, mildew or musty odours

Call in a professional plumber to use leak detection equipment, line cameras and other tools to pinpoint the hidden leak source before costly damage spreads.
