Well said Mr Tieger! 
And if you decide to use copper for your water distribution lines, make sure you use a minimum grade type L copper tube. Unfortunatley many residential contractors in my area have now elected to use a thinner walled type M copper tube in order to save a few bucks. Insist on type L…a little more expensive, but definitly worth it in the long haul. Most engineers call for a MINIMUM type L in their specifications for commercial buildings as well and there is a reason for it…. so have it done right the first time. I would also recommend getting a professionnal licensed plumber to this for you, as the proper sizing of water distribution and drainage lines is of utmost importance, irregardless of the material you choose.
