Hi, I am trying to decide how to run water to my backyard for my irrigation system.
In the picture above, you see the front corner of the house, where the house mainline both enters the crawlspace to feed the house and where it splits to feed the front yard sprinkler valves. The backyard valves need to go just behind the fence you see on the right. There is currently no external hose bib or anything on that side of the house in the back yard.
I figure I have two options. The simpler option would be to tap into the house mainline in the crawlspace, since it runs close to the side of the house, and send a pipe through the exterior wall where I want to install the backyard valves. However, I've heard that one should avoid tapping into the house mainline for various reasons (noise, wear on the pipe, etc.)
The other option would be to trench along the side where all the mulch is and run PVC under the fence, all the way up the side, under the concrete pad and up to the front yard sprinkler point of connection. Clearly much more work, and I know that area also holds the sewer lateral, and probably gas too (you can see the meter in the picture).
What's the best option?
