    Depth below slab surface of sewer rough in California
    As a follow up to this question, I live in CA and I am putting in a bathroom (sink, toilet and shower) installed on a slab. I heard that the sewer line must start at 18" below grade nad start it's run to the main sewer. The only way i can make this (1/4" per foot) is to start with the line at only 10"below the shower (the last drain before it goes out). Since there is no chance of freezing is that OK or do i need to go 18"
