<<<Copper has its own set of problems. It can't be used underground or in concrete. >>> Are you sure this is a general problem with copper, or is copper just banned from use underground and in concrete in your area?,...perhaps because of the characteristics of your ground. The majority of water connections from street main to home in Canada are 1 to 1.5 inch flexible copper set underground below the frost line. The majority of mall pad and commercial building codes also call for flexible or solid copper through concrete and under the pad to the main. I have yet to see plans for any commercial or residential building in Canada calling for plastic either above or below ground for water supply, and I have been involved in hundreds over the last ten years. Many Canadian municipalities currently ban the use of plastic for potable water supply for residential applications. I'm not taking issue with your plastic installation. Properly done there is probably nothing wrong with it, and it will last for decades of problem free service. Most street mains use solid plastic pipe now with plastic couplings. Just wondering why a municipality would ban copper pipe use in concrete or in ground.
