How deep to place plumbing
My question is about a water line in our backyard. Apparently it broke/froze over the winter and on Saturday my husband dug up where the pipe originates (near the house) and where it ends on the far side of the back yard. He concluded that the pipe had broken somewhere between those two points and unless I wanted to dig a new trench the faucet out at the end of the yard (which I used to water a flower bed, trees and my vegetable garden) must be abandoned. He went ahead and cut and capped the line where it is located near the house until a decision could be reached about whether a new line would be ran out to my faucet in the yard. Hope this makes sense.
I really need that faucet out back. I use it constantly during the summer. Question being if I decide to dig the trench to run the line from A to B how deep does it have to be? We generally don't get much colder than 20 degrees out during the winter. I'm trying to work out if the digging is something I can do myself or must hire someone.
Thank you. Sorry kinda long.
