    Copper to PVC
    My house has all copper pipes. However, I noticed that from the street main before the house there is a tee that connects copper to PVC. The PVC branch is connected to my sprinklers and nothing else.

    I am worried that the PVC wasn't meant to be under constant water pressure from the main and that I will have a problem later. Should I replace the PVC with copper. There is about 30 feet of pipe and roots to work through/around.

    I wouldn't worry about it. Even if you have a pressure regulator reducing the pressure inside the house, I am sure both the copper outside and the PVC are rated for 150 psi, well below the delivery pressure. The PVC you have exposed may have the pressure rating on it, or schedule 40. As long as it isn't marked DVW, it should be fine.

    Here in Florida all our water supplies are 3/4" Schedule 40 PVC from meter to house. Your PVC will last much longer then copper. Don't worry, you're fine. Cheers Tom
