First thing comes to mind, is sunlight and the UV rays. So,
what you use should be UV resistant.

White PVC tubing might work for a while. The cost of
fittings might add up. Typically sold in 10 foot lengths,
and the tubing is relatively rigid.

The new "Pex" stuff they sell for indoor water tubing may
work, but not sure how UV resistant it is.

They also sell some grey tubing for electrical conduit,
which might be more UV resistant, but not sure it's used for
outdoor water.

As to winter, may be able to to blow it out with compressed
air, and leave it dry.


I laid a "temporary line" some 200 ft with a 50' side branch with
mostly 3/4" PVC (white) on top of the ground to water newly planted
trees in 1977. Pulled it about 15 years later. Had a few leaks each
spring but fittings are very cheap and patching is nothing but a
hacksaw and tube of glue. Currently using pieces of that same pipe
for another 'temporary' line to bypass a busted frost free hydrant
(can't replace without digging through a mass of tree roots). That
lien is also above ground and only needed one patch this spring
(usually there are several). Line has been in place over 10 years.
