copper vs pvc under patio slab
I am in the process of landscaping our backyard pretty much with a clean sheet of paper. I have the opportunity to run the main feed from the house to the irrigation system & several hose bibs under a as yet unpoured concrete patio slab. In SoCal so freezing not an issue. My options would be 3/4 copper sleeved in plastic or schd 40 pvc. Which would be more durable over time? I've had many issues over the years with pvc systems and while repairs are usually simple this run will be inaccessible after the slab is poured.
