I need to run (extend) a water line from a hose bib to the deck and have a
few questions.
This will be all above ground, visible, 4' down from the original bib, 26'
horizontally around the corner and 6' up to the new bib.
1 Is there some code rules I should know, is it permitted at all? The
original bib has the antisiphon valve.
2 Is PVC sch 40 OK above ground, will UV crumble it in a few years?
3 I plan to paint it gray to blend with the concrete footing. Will this help
with the UV?
4 I plan to use also copper in as short section where many turns are needed,
1/2" copper bends are less bulky than PVC elbows.
5 I plan to come down vertically to a low spot where I place a drain valve
and then go up 2% on the two 13 feet sections around the corner and up to
the deck. I figure that opening the deck faucet and the drain valve should
drain all the pipes including the vertical piece. Hope the vertical piece
will dribble dry even if the top is sealed by the bib.
Location Austin TX, it freeze every winter, but this is for watering plants
so it can be winterized.

Please point out any flaws in this plan, better know now than find out
later.

A garden hose is an alternate solution but wife does not like to walk down
the deck around the corner to shut off.

Thanks
