Talking of Spiraflex hoses, has anyone used these for the headrace or even as low head penstock. I imagine they would be quite convenient to work with, since they are flexible and can take the shape of the ground easily. How much do they cost? Are they available in large enough sizes? Any websites where we can get further information?
