% I just tried out a ram that I built from Cornell Unv. plans and % Lowes parts. The drive pipe is longer than speced and has a 45deg % turn in it, so I teed off a stand pipe below the bend. Works but not % high volume.
i assume you know this, but the pipe from source to stand pipe should be a size greater than the delivery pipe ... and the stand pipe should be at least 3 sizes bigger than the delivery pipe. well that's what i've come across when i've been researching it. % How about some more detail on your system? Why 30ft tall? 30 ft tall because of the layout of the site. i'm trying to maximise drive head into the pump in order to pump the maximum amount of water to the top of the hill. the source to the pump is about 700 ft distance with a vertical fall about 30 ft in total. pumping about 120 ft up a 30 degree slope to the top of the hill and into a tank. minimum of about 5 glns of water going into the pump in the late summer/ early autumn. hoping to get maybe 800-900 glns/day pumped, which would do just fine. since i have to put in a stand pipe just as well to keep the length of the drive pipe down to save on labour trying to make it fit in the site, so thus the stand pipe of about 30ft height. i intended to make it out of 6 or nine inch UV-resistant plastic pipe. my problems would be how to keep something that tall stable, and how to prevent leaks at the joinings. i'd manage the stability thing okay i think cos we have some 35 ft electricity poles lying around, and it would be easy to put that down, anchor it and brace the stand pipe to it.... i suppose my big problem would be keeping joints sealed, because of the constant hammering. any thoughts? ------------------------ Yahoo!
