Re: Polypipe for furrow irrigation....pics
There used to be a guy in town who did nothing but repair aluminum gated pipe and related paraphernalia. He had a pretty good thing going until sprinklers took over. It's been many moons since we've had anything to do with furrow irrigation (and you couldn't pay me to go back), but when I was a kid I made several trips to the shop with Dad or Granddad to get something fixed.
Plus you have gates that get brittle in the sun and break, gaskets that leak, pipe trailer tires that are invariably flat from sitting outside all the time. Once we had lightening strike a 1/4mile string of aluminum and it put a hole on the female end of every joint right under the gasket of the adjoining pipe; not really a problem, but think if we were running a surge valve. It would have been toast. And don't get me started on PVC. Every try to pick up a 30ft joint of plastic with wet sand in the bottom? Now imagine a half mile of that. Not going to be a fun morning. We sold the last of our aluminum pipe for scrap several years ago, now we just need someone to take the plastic.
