conducting water supply to detached garage
 
can somebody shed some light on running pipe underground from a house to a detached garage/shed, i.e. what all is needed to prevent freezing ? some type of insulation, i presume.

thanks,

Ayuh,....
No insulation should be needed,....

It depends on Where you live......
The farther North,.. The Deeper you Dig......
Up in this country,.. about 4' is usually enough,.... 6' if it's crossing a driveway.....
And,...
If you're not coming back Up into a heated structure,....
Get yourself a Frost-Proof hydrant......

washington DC
 
if NY is 4 ft, DC shouldn't need deeper than 3, huh ?

so basically, just bury the pipe with nothing surrounding it, as if it were inside ?

of course, i am not heating the garage
 
what is a frost-proof hydrant ?

is a frost-proof hydrant a glorified sillcock ?
 
so even if i bury the water line 3 ft under, it eventually will come out into an unheated garage. what do i do to prevent it from freezing there, if any (other than heat) ?

or should i say
 
is there a break-resistant special pipe i should get that will at least prevent breakage amid freezing ?

check your building dept for correctdepth.
A frost proof hydrant (you can find at many farm supply stores) has the actual valve mechanism below the frost depth and is set in gravel. A vertical pipe with outlet and valve control handle come out of the ground. When you shut off the water, the excess in the verticel pipe drain into the gravel. That way nothing freezes as everthing is below the frost level.

Check with your building dept regarding approved pipe but freezing is not an issue because it is below frost depth.

also
 
i will have a single faucet at the end, maybe tow maximum (if i decide to have one inside and one outside). normally, if it were indoors, 1/2 pipe would suffice. since i am going outside and burying, any reason to go bigger, e.g. 3/4 ?

thanks,

Ayuh,....

For the underground run I would use 1" Black Plastic Pipe,......
And,.....
If you use Anything but the Frost-proof Hydrant,.....
You're going to have to manually Drain everything above the frost line.....
Probably including the plumbing inside the shed....
