In residential settings, rainwater tank pumps provide water for tasks such as watering gardens, filling swimming pools, and flushing toilets.

Reasons for Safety Switch Tripping

Despite their reliability, rainwater tank pumps may experience issues that lead to safety switch tripping. Some common reasons include:

  • Electrical Overload: Excessive electrical load or short circuits can cause the safety switch to trip as a protective measure.
  • Motor Overheating: Overheating of the pump motor due to prolonged operation or insufficient cooling may trigger the safety switch.
  • Blockages or Mechanical Issues: Blockages in the pump or mechanical issues such as seized bearings can lead to increased motor resistance, prompting the safety switch to trip.

Understanding Water Tanks

A water tank is a container designed to collect and store rainwater or water from other sources, such as wells or boreholes. These tanks come in various shapes, sizes and materials, including polyethylene, steel and concrete. They are used to supplement mains water supply, reduce reliance on external water sources and conserve water during periods of drought.

The Benefits and Types

  • Water Conservation: Harvesting rainwater reduces the demand on mains water supply, conserving precious resources and lowering water bills.
  • Self-Sufficiency: With a water tank, you have a reliable source of water for various purposes, including gardening, livestock and emergency use.
  • Environmental Impact: Using rainwater for irrigation and other non-potable purposes reduces runoff and pollution, benefiting the environment.
  • Water Quality: Rainwater is naturally soft and free from chemicals, making it ideal for watering plants and washing clothes.

What’s Popular?

Some of the popular brands of water tanks in Australia include Bushman Tanks, Pioneer Water Tanks and Kingspan Water Tanks. These brands offer a wide range of sizes to suit different needs, from small residential tanks to large-scale commercial systems.

Common sizes of Water Tanks

  • Slimline Tanks: These tanks are tall and narrow, making them suitable for tight spaces or along the side of a building.
  • Round Tanks: Available in various diameters and heights, round tanks offer versatility and can hold large volumes of water.
  • Underground Tanks: Buried beneath the ground, these tanks are ideal for properties with limited space or aesthetic considerations.

Common Issues with Water Tanks

  • Leaks or Cracks: Over time, tanks may develop leaks or cracks due to age, wear and tear, or improper installation.
  • Blockages: Debris, sediment, or algae can accumulate in the tank, causing blockages in the inlet, outlet, or overflow pipes.
  • Pump Malfunctions: Issues with the pump, such as loss of pressure or failure to prime, can affect the tank’s performance.
  • Overflow Problems: Inadequate overflow systems or clogged overflow pipes can lead to water overflow and potential water damage.
