Koenders Windmill Specs

The Keonders windmill is a very simple unit to troubleshoot for problems. If it's not pumping air it could be one of the following reasons:

  • Diaphragm worn and has a hole
  • Check valves not closing properly
  • Bearings are worn out and have too much play
  • Air leakage from loose clamps or a hole in the airline going to the pond
  • The check valve at the air stone is damaged
  • Put your ear against the leg while you are standing there and listen. You can hear a lot of the problems down at the bottom. The noises will vibrate down to help you troubleshoot the problem.

If a problem arises that you can’t fix, we can put you in contact with the equipment dealer in Ontario. The problem can be fixed while the windmill is still standing, or it can be laid down quickly for easy repairs.
