I am running hot and cold water lines from my house to our detached studio apartment and about 20' of the run needs to be buried across the yard between the house and studio. My plan is to dig a trench about 16" deep, add about 4" of pea gravel, places the pipes, add more pea gravel, and then fill the rest with soil. I'm planning to use 3/4" schedule L rigid copper pipe and am just wondering foilks' thoughts on this approach? None of it will be buried under concrete or otherwise be obstructed from easy excavation if I needed. I live in far-northern coastal California (near Eureka) where it is really wet all winter and spring but rarely do we get more than a mild freeze. The hot water will be provided from the tankless hot water heater in our house, which is sized large enough to handle all of the load.
Any issues anyone can see with any of this? I'm planning to insulate the pipes where they are exposed above ground but otherwise just simply bury them in a bed of pea gravel where underground. Any thoughts, suggestions etc. on this would be appreciated.
