Common Questions
Are windmills still relevant today?
Windmills are still highly relevant today. They remain one of the most practical and dependable ways to pump water on rural, remote, and off-grid properties. As one of the original forms of renewable energy, a windmill can provide ongoing water supply without electricity, fuel, or complex electronics. When correctly maintained, windmills continue to offer a reliable, long-term solution for stock water, property water security, and sustainable rural infrastructure.
How long does a windmill last?
A well-built windmill can last for many decades when it is properly maintained. Across rural Australia, there are windmills still operating after 50, 80, and even 100 years of service. Longevity depends less on age alone and more on the quality of the original build, the conditions it has worked in, and how regularly it has been serviced and repaired over time.
How often does a windmill need servicing?
We recommend a service once a year to check oil levels, tighten mechanical components, and inspect the integrity of the tower and head. The pump itself should be inspected and buckets/ seals replaced every 3-5 years.
Do windmills work without electricity?
windmills operate without electricity. They use the power of the wind to drive a mechanical system that lifts water, making them a practical solution for rural, remote, and off-grid properties. When properly maintained, a windmill can provide reliable water pumping without relying on mains power, fuel, or electronic controls.
Can old or damaged windmills be repaired?
Many old or damaged windmills can be repaired, depending on their overall condition and the extent of wear or damage. At Fetlock Windmills, each windmill is assessed individually to determine the most practical and reliable path forward. In many cases, repairs can return a windmill to safe, dependable working condition, while in others a more extensive restoration or partial rebuild may be the better long-term option.
Are spare parts still available?
Some genuine windmill parts are still available, and wherever possible this is our first preference. At Fetlock Windmills, we also carry a large range of refurbished parts and components to support older and harder-to-source windmills. Where genuine or refurbished parts are not available, we can fabricate and manufacture parts to order for all windmills, helping keep working systems operating reliably for the long term.
Mechanical Indicators of Required Servicing
Regular maintenance is critical for a smooth and functional windmill. Watch for these mechanical signs that your infrastructure requires professional field service:
- Gearbox Noise: Rhythmic clunking or high-pitched squealing from the wheel head.
- Seal Integrity: Oil or lubricant streaks appearing on the tower frame or gear casing.
- Pumping Rate: Significant decline in water volume or intermittent flow.
- Wheel Vibration: Visible shuddering or imbalance during mill operation.
- Furling Response: The tail vane failing to turn smoothly or lock safely in high wind.
