I am making a simple hand pump to bring river water to my vegetable garden. I bought some pvc pipe from a local recycled materials place. It turned out to be electrical conduit pipe. I asked the volunteer if it would ok to use for irrigation water, and he thought it would be fine. But, in reading about elec. conduit pipe online, I'm now wondering if there are chemicals used in pvc conduit pipe (stiffeners, etc.) that could possibly leach into the garden water. Is this a valid concern?
Thanks for any suggestions. If there's any risk, I'll just find some pvc plumbing pipe instead.
