Builders and plumbers will respond to your preference. Copper piping requires no maintenance, because the joint fittings don't break down or pull apart. Copper meets or exceeds building codes in all 50 states. It's governed by strict, long-established standards and is permanently identified for home inspectors. It's a natural, environmentally friendly material - not a synthetic.
Plumbers know how to install and test it, year-round, through a wide range of temperatures.
Since copper is rigid, it doesn't sag over long runs and requires few supports. Copper won't embrittle with age, so it can't crack or crumble years after installation. If, somehow, it does, application of open flame or electrical resistance heating for a brief time can be used to melt frozen water in copper tubing, because copper has superior thermal conductivity. Copper tubing is non-flammable. It won't melt, or burn, or give off toxic fumes in a home fire.
