I am looking at buying a new house and one of the main differences I see in these new subdivisions is the plumbing systems. In the cheaper subdivision they are using plastic for the hot and cold water. It is a semi-opaque clear tubing.
The other system also apears to be plastic. It is 2 different colors, blue and orange.
The more expensive homes are using underground copper.
Are these all tried and true plumbing systems? What have been the problems with each? Does it depend on the skill level of the sub to get a good system? Are the costs between the systems significant?
