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.

I have black polypipe that's been in the sunlight for up to 20
years. The biggest danger to my black polypipe has been from my
garden fork and frost popping the connectors off.


quoteBlack HDPE pipe containing 2 to 2.5% carbon black can be
safely stored outside in the sun without damage from UV exposure.

Some poly pipe can take it and some apparently can not.

It'd be as useless as tits on a man's back if it couldnt' be used out
in the sun in Australia.

Even in Seattle?

Seattle isn't in Australia. And from my limited knowledge of Seattle, I
thought it got lots of rain??????

Only 9 months out of the year. Summer (the other season) is dry-ish.

Mad dog Republicans to the right. Democratic spider webs to the left. True conservatives, and liberals not to be found anywhere in the phantasmagoria
of the American political landscape.

America is not broke. The country is awash in wealth and cash.
It's just that it's not in your hands. It has been transferred, in the
greatest heist in history, from the workers and consumers to the banks
and the portfolios of the uber-rich.
