A caution to consumers: If you have a windmill installed by Priceville Windmill Company (Ontario, Canada), if there is anything wrong with the installation, they will not repair it unless you pay them. There is a whole culture of rural people in southwestern Ontario that will not respond to a callback. Once they have your money you are on your own. This company charges over $125 to change a couple of litres of "Windmill" Oil, and flatly tells you there is nothing wrong with the installation, despite the fact that the whole tower rattles and shakes as the pump rod goes up and down.
