I have gotten along pretty well with orchard tubing, sometimes called flattube but not the same thing as layflat. It is a black plastic pipe with a blue stripe on one side and comes in sizes 1/2" up to 2". It runs 10--20 cents per foot depending on thickness and length. It handles being occasionally kinked or run over by equipment pretty well but does not do as well being run over by bushhogs. If you take care of it it can last 5 or more years. The thing I like about it is the ease of putting pieces together with compression fittings. Taking it apart is a little harder but not all that bad if you are fairly strong. Certainly not as bad as with HDPE, insert fittings and hose clamps.

i've wondered for some time if LDPE (black somewhat flexible water
lines) would be better than our current mainline system of layflat.
layflat is ok. . . certainly cheap, but between vehicles and rodents
it's got a 3 year life at best. are LDPE mainlines a better
alternative? for this coming season i'll likely have 1400' of 1.5"
layflat mains where it's convienent to hit with various mowers (sickle
bar works well). i'd like to get some buried water lines, but the
500$/day rental on a ditcher keeps it a low priority. seems like a
more rigid plastic would be easier to repair, and less vulnerable to
damage. . . but can you leave it out all winter without worries?

thanks

Sarah,

LDPE or low density polyethylene plastic pipe is typically used for
the black plastic pipe that one can see coiled up and for sale in
building supply stores. We use it both under and above ground to move
water. HDPE is used in such things as gallon milk containers. I
would think that HDPE would be a bit rigid for water piping.

Has anyone heard of anyone using HDPE for their underground piping in
agriculture? I know people are using it in other applications but
wondering about its efficacy in ag systems....
