I have to run about 75 feet under a slab in san francisco. It is a storefront that I will use for light use. Anyhow I trenched it out and I am ready to run the line but I don't know what to run. I have been told I have to run L copper Silver Soldered/ braised (which I have never done) with the corrosion protecting sleeve, taped at penetration and covered with drainable fill. I have also been told to run schedule 80 pvc... I read that as of Jan 1 in california you can run Pex in California but I have also never used that before.. I am not having it inspected so I am not so worried about what is SF code (though I would prefer to comply). I just want some more educated ideas on what I should do. As it will be under a slab of concrete I want it to last as long as possible.. Thanks for any and all help..
