Need Advice, Installing Hose Bibb in Detached Garage

[MAW71]

I'm looking for some details on what is involved to run a water line to a detached garage for a outside hose bibb. I plan to run the line off an existing hose bibb from my home, distance is roughly 50-75 feet. I'm at a loss as to what type pvc tubing I would use, how deep it needs to be buried, etc. I'm not to concerned with freezing as I live in south Texas, so it should not be an issue. The bibb would be used to attach a garden hose to wash vehicles.

Any recommendations would be greatly appreciated.

thanks

If I were doing this for myself, which I have, I would Tee off the existing water supply, install a metal ball shut off valve, use metal pipe (galv. or copper) to enter the soil into the 12" deep trench, elbow off with 3/4" PVC and run to where the vertical riser is to be, elbow up using metal pipe above ground level and install a well supported brass hose bib.
The most difficult part is running the trench, otherwise pressurize the completed water line, check for leaks and then back fill the open trench. Make sure the hose bib is braced well, you don't want to crack the PVC down below when someone pulls on the garden hose too hard. You may wish to add and cap off a Tee in the hose bib riser if you wish to extend the water system in the future to a garage wash sink or something of that sort. Easier now than later.

Personally I like to sleeve any pipe I put in the ground. 4" PVC drain pipe is very inexpensive. I would run that in a trench that is at least 12" deep. I'd then run a 3/4" black polyethelene pipe (the stuff that comes in 4' to 5' diameter rolls) inside the 4" PVC. Finally when back filling the trench I'd lay a strip of plastic caution (red is for electrical but works well for anything) about 6" down from the top.

What was said about metal pipe entering and exiting the ground is a also a good idea.

I would do what Cyberbear states.....tee off main water line before it enters your house, that keeps you from coming off from a hose bibb on the house.

problem with pvc is there is no good way to secure it . i would recommend cpvc. you can get it in a 100' coil so no joints underground . next black poly pipe is available from lawn sprinkler and plumbing supply houses , this also comes in 100' coils i would suggest 1" poly as you can easily sleeve 1/2" thru this and 3/4" will also go just a little tougher. takes 2 people stretch it out and slip it through , no grease or anything just a lot of muscle. For cpvc they now offer an adapter that has a bracket to mount to the wall to secure it, one side is 1/2" ips for a hose bibb other side is cpvc. at the existing pipe you might be able to unscrew it ,screw in a ****** with a tee on it ,then reinstall the hose bibb and on the open end install a ball valve . FYI cpvc uses no primer just glue
