Frequently Asked Questions

  • What areas do you service?

    Northern Plumbing provides a wide range of plumbing services for Douglas and the surrounding areas, including Annandale, Cranbrook and Heatley. Contact us to confirm whether we service your specific location.

  • Are all water leaks visible or easy to detect?

    Not all water leaks are obvious. Many occur in hidden areas like under floors, behind walls, or in roof cavities, and may not show visible signs until significant damage has occurred. Clues to hidden leaks include unexplained increases in water bills, damp smells, discoloured walls, or warped flooring. You may also hear dripping or running water when no taps are in use. Leak detection equipment such as thermal imaging and moisture sensors can locate these problems accurately without damaging property. Early detection is key to preventing mould growth, structural issues, and higher repair costs, so it’s best to act quickly.

  • Why does my toilet keep running after flushing?

    A running toilet usually means water continues flowing into the bowl due to a faulty flapper valve, fill valve, or float mechanism inside the cistern. These components regulate water flow and stop once the tank refills. If any part becomes worn or misaligned, water may leak continuously from the cistern into the bowl, wasting significant amounts of water. You may hear a constant trickling sound or notice frequent refilling. Some issues are easy to fix with replacement parts, while others require adjusting the float or flushing mechanism. If unsure, a plumber can quickly diagnose the cause and perform a proper repair to restore function and reduce water waste.

  • How do I know if my hot water system needs servicing?

    If your hot water system is producing inconsistent temperatures, making unusual noises, taking longer to heat, or causing higher energy bills, it may need servicing. Other signs include rusty-coloured water, low pressure, or water leaking from the base of the unit. Annual servicing is recommended to keep the system running efficiently and extend its lifespan. During a service, a plumber will inspect components, flush the tank (if applicable), check for sediment build-up, and test the thermostat and pressure relief valve. Regular maintenance helps avoid costly breakdowns, improves safety, and ensures you’re getting the best performance from your system year-round.
