Outside Hose Bib
 
Hi

I want to install an outside hose bib a distance from my house where
there is no water available. Where it leaves the house it will get
exposed to the sun (U.V.). Then... It will be underground until I pop
back up to the bib location.

What type of pipe should I run? I understand PVC will get brittle if
exposed to UV rays. Can I use PE (the same as a sprinkler system?) Will
CPVC work? Should I run CU all the way? Do I need a special pressure
rating?

I have searched all over but see nothing on outside pipes.

thanks!

Galvanized pipe.

My dad has white SCH 40 PVC risers that are over 20 years old down in
Texas in the hot sun and they haven't cracked yet. Maybe he has just
gotten away with it because the water pressure is not very high.

You can use gray SCH 80 pipe for the risers, and I think it is UV
resistant. You also might try using SCH 40 gray PVC electrical conduit
for the risers; it is UV resistant and compatable with PVC water pipe
fittings, but it's not pressure rated, nor certified for use with
potable water. (that wouldn't matter to me for irrigation pipe)

You could always run thinwall PVC underground, then put a threaded
fitting on the end and transition to galvanized pipe for the riser.

Best regards,
Bob

What I would do is to dig a trench from the foundation wall out to the
new hose bib location with the entire trench below the frost line for
your locality. You could then install a frost proof hose hydrant and
not have to worry about early or late frost damaging the piping before
or after you have reopened the cut off valve in the house.

If the trench will be twenty of more feet long and thirty or more inches
deep you have a good opportunity to improve the grounding of your homes
electrical system. If you tell me what your present grounding electrode
system consist of I can tell you if it would be worth doing.

No conscientious electrician ever ignores an open trench.
